DGMS Annual Report,2009A-1 1.0 Introduction Under the Constitution of India “Regulation of Labour and Safety in Mines and Oilfields” is a central subject (Entry 55 of the Seventh Schedule of Article 246). The matter is regulated by the Mines Act, 1952 and the Rules and Regulations framed thereunder. It extends to whole of India including territorial water i.e. upto 12 nautical miles in the sea measured from appropriate base line. These statutes are administered by Directorate-General of Mines Safety (DGMS) under the Union Ministry of Labour & Employment. 1.1 Historical Background Although exploitation of minerals has been going on in the country from pre-Christian era, it was only towards the end of 19th Century that attempts were made by the state for regulation of employment and working conditions therein. Following the International Labour Conference in Berlin in 1890, the then Government of UK through the Secretary of State for India asked the Government of India to consider the desirability of undertaking legislation for inspection of mines in general and coal mines in particular and for regulation of employment therein of men, women and children. Accordingly in 1894, Mr. James Grundy was appointed as first ever Inspector of Mines in India within the organization of Geological Survey of India. Mr. Grundy recommended that provisions be made for the minimum age of employment; notice of opening and of accidents, first-aid, management and supervision etc. Major disasters at Kolar Gold Field in 1897 and at Khost Coal Mines, Baluchistan (presently in Pakistan) in 1898 expedited finalisation of the first Mines Act which was enacted on 22nd March, 1901. A Bureau of Mines Inspection was started in Calcutta on 7th January 1902 to administer the provisions of the Mines Act, 1901. The organization was renamed as Department of Mines and its office was shifted to Dhanbad in 1908. In 1960, the organization was renamed as Office of the Chief Inspector of Mines. Again in 1967 the name of the organization was changed to Directorate- General of Mines Safety (DGMS). In 1988 DGMS was declared a Scientific and Technological Organization. Apart from administering the Mines Act and legislation framed thereunder, DGMS also administers certain allied legislation. A list of legislation administered by DGMS is given at Appendix-I. 1.2 Organizational Set-up of DGMS Directorate-General of Mines Safety is a multi-disciplinary organization with Inspecting Officers from Mining, Mechanical and Electrical engineering and Occupational Health disciplines. Officers appointed to different technical posts in DGMS are selected by U.P.S.C. They are required to have Degree in Mining or Mechanical or Electrical Engineering with several years of experience, varying from seven to ten years of working in responsible capacity in mines or allied industry. Besides, officers of mining cadre posses First Class Mine Manager's Certificate of DGMS Annual Report,2009 A-2 Competency. The Occupational Health cadre is manned by qualified and experienced medical personnel. The organization has its headquarters at Dhanbad (Jharkhand) and is headed by the Director- General of Mines Safety. At the headquarters, the Director-General is assisted by specialist staff-officers in mining, electrical and mechanical engineering, occupational health, law, survey, statistics, administration and accounts disciplines. The headquarters has a technical library and S&T laboratory as a back-up support to the organization. Extensive computerization has been done in head office and in the field offices to upgrade the standard of work. The head office and some of the field offices have access to the internet enabling these to place themselves at par with other developed countries of the world so far as the communication with the use of computer is concerned. DGMS has a plan to establish a network for all its offices through Internet. A web page on DGMS has already been launched during the centenary year. The field organization has a two-tier network of field offices. The area of jurisdiction of DGMS covering the entire country is divided into 8 zones, each under the charge of a Deputy Director- General. There are three to four Regional offices under each zonal office. Each Region is under the charge of a Director of Mines Safety. There are in all 29 such Regional Offices. Sub- regional offices have been set up in important areas of concentrated mining activities away from Regional office. There are 3 such sub-regional offices, each under the charge of a Deputy Director. Each Zone, besides having inspecting officers of mining cadre has officers in electri- cal, mechanical engineering and occupational health disciplines. Organization chart of DGMS are at Appendix-IIA & IIB. Table - 1 shows the discipline-wise strength of inspecting officers as on 31.12.2009. A statement showing posting of Group „A‟ & „B‟ officers in DGMS during the year 2009 are given at Appendix-III.

Setting standards, by overseeing compliance thereof as intensively as the resources permit and through a variety of promotional initiatives and awareness programme, the officers of DGMS exercise preventive as well as educational influence over the mining industry. DGMS is also promoting the concept of „self-regulation‟ as well as 'workers' participation in safety management. With changing scenario, attempts are being made to superimpose its traditional role of seeking compliance by legal sanctions and work prohibition optimally, with advisory and other safety promotional initiatives; thereby creating an environment in which safety is given due priority. Current functions of DGMS broadly include: 1. Development and updating of legislation and issue of guidelines and circulars periodically. 2. Inspection – overseeing compliance of the statutes by the management through sample inspection as and when required 3. Investigation into: (a) accidents (b) dangerous occurrences - emergency response (c) complaints & other matters and (d) taking corrective action and action against delinquents 4.

While the onus of providing for and ensuring safety in mines rests with the mine management, DGMS has the DGMS Annual Report,2009 A-5 responsibility to see that the safety statute is kept updated to absorb the technical advancements as well as to make the same comprehensive, practicable, legally sound and also to carry out periodic inspection of mines to oversee compliance of safety laws. The Mines Act and the subordinate legislations framed thereunder is periodically updated for the purpose. Each and every accident involving fatality is enquired into by an officer or a team of officers of DGMS. A few accidents involving serious bodily injury and most of the important dangerous occurrences are also investigated by DGMS Officers. Arising out of inspections and enquiries conducted by DGMS, one or more of the following actions, as appropriate, is taken: - (a) drawing the attention of the mine management about the contraventions of the statutes etc.; (b) withdrawal of statutory permission, approval, relaxation or exemption granted ; (c) serving an improvement notice ; (d) imposition of a prohibitory order ; (e) suspension of statutory certificate of competency held by managerial and supervisory personnel, if found negligent in the discharge of duties; (f) prosecution of person(s) held responsible; (g) punitive action taken departmentally by mining companies. Mine management is also addressed to take steps as are considered necessary by the inspecting/enquiry officer to rectify the defects or deficiencies in working condition or system. 1.6 Inspection & Enquiries Discipline-wise number of inspections and enquiries made by the inspecting officers are given in table:3.

DGMS Annual Report,2009 A-17 2.2.3B.1 Ground movement During the year 2009, ground movement accounted for 26(31%) fatal accidents and 57(9%) serious accidents. Further break-up of fatal accidents due to ground movement is given in table 22.

Experience of the past clearly brings out that roof fall is one of the predominant causes of fatalities in belowground coal mines and that trend continues even today. There were 26 accidents due to ground movement involving 32 fatalities and 07 serious injuries during the year 2009, out of which 17 accidents were due to fall of roof, 7 accidents were due to fall of side and 01 each due to landslide and over hangs. Roof fall accidents accounted for 20% of all fatal accidents in coal mines and it contributed 44% of all fatal accidents in belowground operations. Further critical analysis of roof fall accidents for the last five years 2005 to 2009 revealed the following: I. Physical and Working Condition factors - 1. Method of work: Accident mainly occurred in Bord and Pillar districts. 45% of the fatal accidents occurred in B&P development, 45% in depillaring districts (35% in caving districts and 10% in stowing districts), 2% in longwall stowing and 7% in other places. 2. Height of working: 80% of the fatal accidents occurred in gallery height upto 3m, 20% in 3m to 5m. 3. Width of gallery: 2% of the fatal accidents occurred in width of galleries between 0 - 3.0m and 4% in width between 3.01 -3.5m, 17% between 3.51-4.00m, 40% between 4.01 -4.50m and 35% occurred in width of galleries above 4.50 m. 4. Distance from face: 42% of the accidents occurred within 5m of the working face and 15% each between 5.01 to 10m and 20.01m & above, 8% in 10.01m to 20.00m. DGMS Annual Report,2009 A-18 Thus 57% of the accident occurred within 10m of the freshly exposed roof from the face of working. 5. Type of support: 18% of the fatal accidents occurred in areas supported by timber support only, 4% in timber & steel supports, 22% in roof bolts & others and 56% in other supports. However, areas supported by roof bolts were more prone for roof fall. Steel supports, especially roof bolts, are more stable if they are fixed properly and in time. 6. Adequacy of support: Accident analysis revealed that in 60% of cases supports provided was inadequate, which means sufficient number of supports were not provided before engaging persons at work and majority of the accidents could have been averted had proper supports were provided before engaging the persons at work and front line supervisors been attentive for providing adequate supports. It also reveals that in 36% cases accident occurred although adequate support was provided. 7. Operation at the time of accident: 15% of the fatal accidents occurred during loading (manual) operation, 12% during dressing, 7% during supporting and 4% during dressing & supporting, thus 38% of the accidents occurred during primary job of face preparation and manual loading. This can be avoided by adequately training the face workers for paying more attention towards identification of bad roof and testing for its weakness and by providing temporary supports before erecting permanent support. 11% each of the fatal accidents occurred during withdrawal of support, 13% occurred during loading by machine and 20% due to other activities. 8. Time elapsed after blasting: 26% of the roof fall accidents occurred within 30 minutes of blasting operation which correlates with the operation at the time of accident as mentioned above. This also means that sufficient time was not allowed for the roof to settle before engaging persons. 6% of the fatal accidents occurred between ½ - 1 hour, 11% between 1 to 2 hours and 29% of the fatal accidents occurred beyond 2 hours of blasting operation and in 28% of cases no blasting operation was carried out. II. Geological factors - 9. Thickness of seam: 40% of the fatal accidents occurred in coal seam having thickness upto 3.0 m., 33% in 3 to 6 m. and 11% in seams with thickness between 6- 9m. Thus roof fall occurred in all types of coal seams irrespective of their thickness. 10. Depth of cover: 33% of the fatal accidents accounted in depth of cover upto 100 m, 36% in 101 to 200m. and 22% between 201 to 300. Practically roof fall accidents occurred at every place irrespective of the depth in proportion to the working plan at various depths except for depth of cover above 401m. 11. Thickness of fall: 17% of the fatal accidents occurred having thickness of fallen strata varying between 0 to 0.15m, 32% between 0.16 to 0.30 m. Thus 49% of DGMS Annual Report,2009 A-19 accidents had thickness of fall between 0 to 0.3m. 33% of fatal accident occurred having thickness of fallen strata between 0.31 to 1.0 m thick and 18% occurred beyond 1.00m thick. Fall of roof was mainly due to geological reasons such as presence of slicken sides, hidden slip planes, or due to weathering of strata etc. which could have been effectively controlled had adequate and timely supports been provided. 12. Nature of fallen strata: 46% of the fatal accidents occurred due to fall of sand stone roof, 20% due to shale and 18% due to coal and rest of the fatal accidents occurred due to combination of any two. It indicates that practically all types of roof are likely to fall in absence of adequate supports. III. Personal factors - 13. Designation: 38% of the persons involved in roof fall accidents were loader, 18% timbermen, 10% subordinate supervisory staff, 9% dressers and 3% shotfirer/explosive carrier. Mainly face workers were involved in the accidents as they are first to approach the face and stay beneath the green roof areas for longer duration. 14. Age: In 28% of the total accidents persons involved were in the age group of 46-50 years, 15% between 41-45 years, 17% between 56-60 years, 13% between 36-40 and 12% between 51-55 years. 15. Shift of working: 60% of the fatal accidents took place in 1 st shift, 22% in 2 nd shift and 18% 3 rd shift. Thus it is observed that roof fall occurred mainly in first shift due to more number of persons employed during day time. 16. Hours at work: 18% of the roof fall accidents occurred each in 3.01 – 4.00 and 4.01 – 5.00 hours of the work, 15% between 5.01 – 6.00 hours and 7% between 6.01 – 7.00 hours. Thus 36% of the roof fall accidents occurred between third and fifth hours of the shift. IV. Management factors - 17. Responsibility: 44% of the fatal accidents were caused due to fault of management and Subordinate Supervisory Staff; 17% of the fatal accidents due to fault of Subordinate Supervisory Staff alone, 5% due to fault of management and others and in 4% of the cases subordinate supervisory staff and other were held responsible. In 5% of cases deceased was responsible. 18. Company: Company-wise analysis indicates that 73% of roof fall accident occurred in CIL whereas 20% occurred in SCCL. CIL subsidiary-wise 24% of fatal accidents occurred in BCCL, 18% in SECL, 11% in ECL, and 14% in WCL.

Spontaneous Heating In total 12 (twelve) cases of spontaneous heating were reported and all 12 were in belowground workings. Three of them resulted into blazing fire. There was no incidence of spontaneous heating in opencast workings. There was one case of spontaneous heating inside the caved goaf under shallow cover. There was one case of spontaneous heating due to leakage of air inside sealed off area. There was one case of spontaneous heating as the area was not kept sectionalised and the ventilation was not adequate. There was one case of spontaneous heating due to more loss of coal. There was one case of spontaneous heating due to lag in stowing. There were three cases of blazing due to spontaneous heating. Contributory factors for spontaneous heating: The primary contributory factors which lead to spontaneous heating and thereby fires: Non-sectionlization / improper sectionlization of old workings. DGMS Annual Report,2009 A-36 Not cleaning the old galleries and return airways off fallen coal and not treating thoroughly with stone dust. Sluggish ventilation in old workings and depillaring areas. Working the depillaring panel beyond the incubation period. Not filling up the surface cracks formed due to subsidence and causing leakage of air into the sealed off areas and old workings. Not making and maintaining the isolation stoppings as prescribed. Non provision of latest carbon monoxide gas detecting devices. Corrective measures: Rate of extraction has to be made faster by deploying well maintained loading machines and loss of coal in the goaf has to be minimized. Isolation and sectionlization stoppings have to be regularly inspected as per statute to detect early stage of spontaneous heating. Strengthening of old stoppings. Fallen loose coal has to be cleaned off regularly. Surface area above the goved out panels shall be filled up to avoid breathing of air. All the galleries exposed on the side of entries to the belowground workings in the seam shall be covered effectively to avoid breathing of air through those galleries. Rib of coal left as barrier between opencast working and belowground working need to be covered to prevent formation of return circuit through the cracks/fissures developed at the surface. B. Other Fires There was a case of fire in dry vegetation extended upto the old tyre stock yard of the excavation workshop. There was a case of fire in shale debris as carbonaceous material dumped in haul road caught fire due to fire in dry vegetation. There was a case of fire in conveyor belt of rapid loading system. There was a case of fire in drill m/c during the break down maintenance in an open cast mine. There was a case of fire in 550v cable due to three phase short circuiting at the cable joint box. Corrective measures: Timely action has to be initiated if active fire is known be existed behind the stoppings. Reinforcement of stoppings and cleaning of return airway to prevent choking shall be done. Adequate precautions shall be taken as per statute while using flame or electric welding or repairing apparatus belowground as well as in opencast workings. Proper code of practice for prevention of fires in HEMM should be framed and implemented. DGMS Annual Report,2009 A-37 Availability of Fire Tender in the mine must be ensured. C. Premature collapse of workings or failure of pillars/benches In one case top three benches including the embankment made against a nallah slided (quantity is about 18,000m3). In one case there was a major roof fall in the depillaring area where „Limited Span Method‟ was in practice. In another case roof fall occurred where „Wide Stall‟ method was in practice. D. Influx of Noxious Gases There was no case reported. E. Ignition or occurrence of inflammable gas There was one case of ignition of inflammable gas and one case of accumulation of inflammable gas as reported. F. Irruption of water / Landslide There were two cases of irruption of water due to pot holing reported. G. Subsidence / Potholing There were one case of subsidence due to low cover and one case of pot holing due to shallow depth reported. DGMS Annual Report,2009 A-38 2.4 Technical Developments During the year 2009, 11.97% of the total production came from underground workings and 88.03% of the total production came from opencast mines. As far as average daily employment was concerned 50% were employed belowground, 21% were employed in opencast workings and the remaining 29% were employed for other surface operations. During the 2009, 1320 Excavators, 5324 dumpers capacity varying from 35T to 170T, 920 drills of 50 mm to 250 mm, 40 draglines were used in opencast mines.

Percentage wise there were 15 (35% of the total) fatal accidents due to ground movement in the year 2009 as compared to 14 (25% of the total) fatal accidents due to ground movement in the year 2008. 3.2.2.1A Roof fall Accidents There were 4 (7.41% of total accident) fatal accident occurred due to roof fall during the year 2009 in non-coal mines. 3.2.2.1B Side fall Accidents There were 9 (16.67% of total accident) fatal accidents occurred due to side fall during the year 2009 in non-coal mines. 3.2.2.2 Transportation machinery (Winding) There was no accident reported due to transportation machinery (winding) during the year, 2009. DGMS Annual Report,2009 A-61 3.2.2.3 Transportation machinery (other than winding) There were altogether 11 (25% of all fatal accidents) accidents involving 11 fatalities due to transportation machinery (other than winding) during the year 2009. The cause-wise details may be seen from the following table:- TABLE-40 FATAL ACCIDENTS DUE TO TRANSPORTATION MACHINERY IN NON COAL MINES IN YEAR 2009 Sl. No. Causes Fatal Persons Killed 1. Rope Haulages - - 2. Conveyors 1 1 3 Dumpers/Tippers 8 8 4 Wheeled Trackless(Truck,Tanker etc.) 2 2 5. Others (Wagon) - - Total 11 11 The analysis of causes revealed the following: Transportation machinery (other than winding) Conveyor: One person died due to crush between running drum and belt. Dumpers/Tippers: Eight accidents occurred causing eight killing due to truck and tanker contributing (72.7%) of total accidents due to this cause: Two accidents due to brake failure of dumper and tipper. Six accidents due to ran over of dumper and tipper. Truck & Tanker: Two accidents occurred causing two killing due to truck & tanker contributing (18.1%) of total accident due this cause. Other (Wagon): There is no accident due to this cause during the year 2009. 3.2.2.5 Accidents due to machinery other than transportation machinery.

DGMS Annual Report,2009 A-83 6.0 National Safety Awards (Mines) 6.1 Introduction During the post-independence era, the mineral industry in India has achieved tremendous growth and also imbibed the latest mining technologies. Along with this growth, there has been corresponding awareness of the need to protect the health and lives of workers. The Constitution of India casts an obligation on all of us to ensure just and humane conditions of work. To give due recognition to outstanding safety performance at the national level, the Ministry of Labour, Government of India, instituted the National Safety Awards (Mines) in 1983 for the contest year 1982. 6.2 Scope The scheme is applicable to all mines, which come under the purview of the Mines Act, 1952. Such mines have been classified into 7 groups as given below: i. Coal mines - Below ground with difficult mining conditions ii. Coal mines - Belowground (others) iii. Coal mines - Opencast iv. Metal mines - Mechanized opencast v. Metal mines - Manual opencast vi. Metal mines - Belowground vii. Oil mines 6.3 Schemes Among different indices available, the following two have been accepted as indicator of safety performance: 1. Longest accident free period (LAFP) in terms of manshifts worked during three consecutive years ending with the contest year. 2. Lowest injury frequency rate (LIFR) during three consecutive years ending with the contest year. It is expected that every mine shall endeavour to improve its safety performance. A bad mine has a high injury frequency rate. After obtaining a breakthrough, its next attempt should be to achieve longest accident-free period in terms of manshifts worked. 6.4 Awards Committee The awards committee is constituted by the Ministry of Labour & Employment with Director- General of Mines Safety as its Chairman, eight representatives of mine managements, eight representatives of trade unions and an officer of DGMS as its Member-Secretary. DGMS Annual Report,2009 A-84 6.5 Mode of operation An advertisement is released through DAVP in English, Hindi and other regional languages inviting applications in prescribed proforma for National Safety Awards (Mines). An entry fee of Rs.100/- per application is charged through a crossed IPO drawn in favour of the Administrative Officer/DDO, DGMS and payable at Dhanbad Post Office. The prescribed application form is jointly signed by the mine management and a workers‟ representative. 6.6 Presentation of awards National Safety Awards (Mines) for the contest year 2007 was given away on 23 rd October 2009 at New Delhi by the Hon‟ble Vice President of India. 7.0 Conference on Safety in Mines The Conference on Safety in Mines is a tripartite forum at the national level in which the employers‟ representatives, the trade unions‟ representatives, the Government represented by Ministry of Labour & Employment, DGMS, various administrative ministries/departments and State Governments and associated institutions, professional bodies, service associations, etc. take part. They review status of the safety in mining industry and the adequacy of existing measures in a spirit of mutual cooperation. The conference also suggests measures for further improvement in safety, welfare and health of mine workers. The first such Conference was held in the year 1958 followed by the 2 nd in July, 1966, the 3 rd in 1973, the 4 th in 1978, the 5 th in 1980, the 6 th in 1986, the 7 th in 1988, the 8 th in 1993, the 9 th in 2000 and the 10 th Conference was held on 26 th & 27 th November, 2007 in New Delhi. DGMS Annual Report,2009 A-85 8.0 Plan Schemes In order to provide in-house technical support to field offices, DGMS is implementing following Plan Schemes namely: Ongoing schemes: (1) “Mine Accident Analysis and Modernization of Information Database (MAMID)” (2) "Strengthening of Core Functions of DGMS (SOCFOD)” 8.1 “Mine Accident Analysis and Modernization of Information Database (MAMID)” This is the restructured plan scheme after merging of the two Plan Schemes of Tenth Plan (2002-07) namely (i) Study of Mines Accidents and Development of Mines Safety Information System (SOMA) and (ii) Modernization of Information Database in DGMS (MID) as per the Report of Working Group on Occupational Safety & Health for 11 th Five Year Plan 2007-12 of Ministry of Labour and Employment, Government of India. - Oct 2006. Keeping the objective of integration in view, these schemes were merged into one scheme “Mine Accident Analysis and Modernization of Information Database (MAMID)” Objective of the Scheme: (A) Mine Accident Analysis and Information Database To eliminate risk of disasters and accidents in mines through detailed analysis of accidents and dangerous occurrences using risk assessment and risk management techniques; Development of standard Safe Operating Procedures (SOPs) and Code of Safe Practices (COPs); Identification of mines having potential of accidents/disasters through detailed investigation into the operating systems and environment in the mine; Development of mine data acquisition system and analysis through computerized databases and processing system; Dissemination of mine information system through various reports, technical instructions/guidelines, circulars on electronic as well as other conventional media; Identification of mines having high accident potential and formulation of risk elimination/management plan; DGMS Annual Report,2009 A-86 (B) Computerized Mine Safety Information System Computerization of process and procedures on Mine Safety Information in DGMS; Establishment of Communication Network using LAN and WAN in DGMS; The major activities taken up during the year included – Publication of Annual Report, 2008 and compilation of Annual Report for the year 2009. Publication of Standard Note on DGMS as on 1.1.2009 Analysis of data for Identification of accident-prone mines in respect of coal & lignite mines. Compilation of statistics and preparation of manuscript for – o Statistics of Mines in India, Vol.I (Coal), 2008 o Statistics of Mines in India, Vol.II(Non-Coal), 2008 o Monthly Review of Accidents and o Report on Monthly Inspection Analysis National Safety Awards (Mines) for the contestant years 2007 was given away. Accident Prone Mines: A modified approach for identification of accident-prone mines was adopted; data from all the mines of eleven coal companies were collected. In-depth analysis of all fatal and serious accidents that occurred in all 519 coal mines and 10 lignite mines of the country during the periods 2005-2009 were made and based on the outcome of the study, the accident-prone mines were identified. This was done with a view to identify hazard potential of such mines and draw up action programmes for formulation of mitigating measures through collective efforts of Mine Management, Trade Unions and the Government. The following table shows the number of accident-prone mines identified in different coal companies in last five years. Name of company Number of mines identified as accident prone 2005 2006 2007 2008 2009 ECL 9 8 6 7 7 BCCL 8 6 8 7 12 SECL 8 6 8 5 8 MCL 3 1 1 2 5 WCL 9 8 7 7 8 CCL 7 4 6 2 7 NCL 1 1 1 1 3 NECL 0 0 1 1 1 SCCL 10 5 6 4 7 TISCO 2 1 1 2 1 IISCO 0 1 1 1 1 Total 57 41 46 39 60 LIGNITE - 1 3 3 2 The respective companies were advised to take suitable steps from technical and management point of view to identify the potential risk of the respective mines and to device DGMS Annual Report,2009 A-87 suitable corrective measures and implement the same in a time bound period so that the accidents are reduced. Reports of enquiry into all fatal accidents were scrutinized. Finalized causes and circumstances leading to these accidents were compiled for inclusion in DGMS Annual Report. 8.2 "Strengthening of Core Functions of DGMS (SOCFOD)” This is a continuing plan scheme. The scheme had been formulated by merging three on- going plan schemes of DGMS, namely (1) "Augmentation of S&T Capabilities, Mine Rescue Services and Human Resource Development (S&T)(1975)", (2) “Strengthening of Machinery for Conduct of Statutory Examinations (SSEX)(2000-01)” and (3) “Improving Efficiency by Providing Infra Structure Facilities in DGMS (PIF)(" along with components like Occupational Safety and Health Surveillance, promotional initiatives and Emergency Response system.

Sub:- Surveyed off equipment in the open cast mine. Investigation into the number of accidents have revealed that the accidents are increasing due to surveyed off equipments being used in opencast mines. Each company has a system of surveying off and condemning the equipment depending on the life either by number of working hours or number of years completed. Once the equipment attain the designed life, the equipment are surveyed off but the replacement has not been received. In this circumstances management has no other alternative but to use these surveyed off equipment to achieve production. During this course of time the equipment are not maintained properly and also do not get required spares causing dangerous occurrence or accidents. In order to reduce/avert accidents and untoward incidents, the following steps are recommended to be taken before the surveyed off equipments are put into services. 1. (a) Committee consisting senior technical officer from company level, Original Equipment Manufacturer (OEM) and an independent agency shall make a through check and inspect the condition of equipment and advise the management for necessary maintenance/repairs to be carried out.

Head gear is a important structure located over the shaft that houses one or two sheaves, carrying winding ropes, flexible guides and other equipments. The head frames are constantly subject to static loads, dynamic loads and environmental effect. Foundations of reinforced concrete is buried in ground and is constantly subjected to reversible loads and environmental effects, which reduces the strength of concrete an alters the properties. Failure of foundation is most dangerous for headgear frames. Hence a time to time the structural audit for safety, stability, serviceability and durability must be done to assess the damage. Regulation 73(1) of Coal Mines Regulations, 1957 & Regulation 80(1) of Metalliferous Mines Regulation 1961 requires that “every part of a winding installation, including headgear, shall be sound construction and adequate strength, and shall be maintained in safe working order. In case of any doubt as to the foregoing, it shall be referred to the Chief Inspector of decision. Regulation 182 of the Coal Mines Regulation, 1957 & Reg. 172 of the Metalliferous Mines Regulations 1961 require that “all parts and working gear, whether fixed or moveable, including the anchoring and apparatus used as or forming part of the equipment of a mine, and all foundations in or to which any such appliances are DGMS Annual Report, 2009 154 anchored or fixed shall be of good construction, suitable material, adequate strength and free from visible defect and shall be properly maintained. Head gear frame are generally not maintained for serviceability. Some of the members are removed for the convenience making structure unstable. Initial defects of fabrications of bolts, rivets are enlarged. Improper coating for protection of structure leads to corrosion of steel and reduction of properties due to environmental effects. Mishandling of structure leads also to deterioration of structure. Durability and serviceability of head gear depends on constant watch on structure and audit for its stability. Material properties changed during service life need to be checked and identified. Following important factors are to be carried out from time to time verified with the original. Check to be carried out:- 1. Study the change in static and dynamic loads. 2. Evaluate change in configuration of head gear. Forces in members are to checked and a diagram to be drawn to ensure resultant failing inside back leg. 3. Joints of members are to be checked (rivets, welds, bolts) 4. Strengths of material must be ascertained by taking samples. 5. Deflection and physical movement in all direction and vibration should be measured by applying 50%, 100%, 120% loads. Deformation of frame, buckling of each individual members in joint are need to be checked. Cracks/defects shall be carefully checked. 6. Plastic stage of sections used should be checked by observing change in colour and ductility of section. 7. Ultra sound pulse velocity (N.D.T.) should be done to assess the strength cracks or defects in concrete. Concrete core may also be taken to assess the compression strength of concrete by N.D.T. Cover meter test or hammer tests may be carried out to assess the damage. Rehabilitation of Head gear After full condition assessment and structural audit of the head gear frame for all points mentioned above scheme of rehabilitation and bringing back to original condition shall be prepared. Scheme of retrofitting and rehabilitation will vary from mine to mine. Broadly classified items rehabilitation are mentioned below :- 1) Retrofitting of members to maintain original stable configuration of structure. 2) Bringing back to original properties of materials and section by adding additional structure member. 3) Replacement of bolts, welds, rivets and correcting the perfect alignment of member. 4) For unstable head gear frame, deflection, physical movement is corrected. 5) Apply low diffusivity coating like epoxy to whole structure surface. 6) Grout, shotcrete, inject or jacket polymer concrete to strengthen the foundation of head gear frame and fill up the cracks in the concrete. The structural audit of head gear shall be carried out once in five year. I am sure that in the interest of safety, all mining Companies shall take immediate action to implement the above recommendations.

Sub :- Qualitative and Quantitative assessment of Fire Fighting Equipment. Sir, It is well known fact that air, water and fire are primary sources of lives on the earth but at the same time if the natural equilibrium of any one is disturbed then it leads to disaster and irreparable damages. Fire hazards amongst all the three are very common in the industrial as well as domestic fields. Fire is coal mines is one of the most common hazards that lead to disasters, accidents loss of valuable lives and damages to properties. Spontaneous heating and combustion in coal is one of the major sources of fires not only in belowground workings but also in opencast mines. Bench fire in coal mine is very common apart from dump fire. Increased mechanization and use of large number of machines of higher capacities have posed another fire threats and the incidences of fires in such machinery and installations have increased. One of the major contributors to fire is the use of electricity at higher operating voltages. The fire fighting technologies and fire suppression system have advanced further which are more fast and effective to deal with fires either on surface or belowground including heavy earth moving machinery. A few of such technology is backpacked and handheld High Pressure Water Mist cum CAFs based fire fighting system which is applicable to quench not only oil fires but even electrical fires upto 36 KV line. A live demonstration of this product was given in DGMS recently in the pressure of Officials from Coal Mining Industry, Scientist from CIMFR, Indian School of Mines and other Fire Fighting Equipment manufactures as per EN3-7 Standard B233.135 liters of diesel and 25 Liters Petrol were ignited for 60 seconds to grow the fire and flames upto its maximum intensity and then the handheld High Pressure Water Mist cum CAFs based fire fighting system was operated and applied on the fire blazing upto 30 feet height. The fire was completely quenched within 12 second which appeared to be miraculous to everyone witnessing the demonstration. Similarly, the CAFs were also applied on live electrical wires/fire which was also quenched without any difficulty. High Pressure Water Mist cum CAFs based fire fighting system is highly effective and fast in quenching and controlling fires of varying magnitudes. A survey was recently conducted in few coal mines and installations to identify the risk of fire areas and installation based on quantitative assessment of sources of fires and its magnitude of damage. The survey revealed that the following places, machinery and installation should be provided with at least the required number of High Pressure Water Mist cum CAFs based Fire Fighting System or such other equivalent type or even better.

Sir, 1.0 INTRODUCTION Lighting is an essential environmental component for any working place, whether buildings, roads, offices, factories, stationery or mobile equipment, machines or any other installation and plants. It has a direct bearing on the efficiency of manpower and machine in addition to its effect on personal health. It is also well established that inadequacy of light and long exposure to inadequate lighting conditions lead to numerous eye slight problems and ill effects on human body. It is also known that over exposure to light is equally dangerous to human body. Various researches and studies have been carried out on this subject and different standards of lighting for specified objectives and operations have been prescribed by different countries and Standard Organizations. Bare lamps causing glare are still in frequent evidence. In many cases the quantity of light generated is sufficient, but only a small percentage of the light reaches the work, by reason of failure to equip the lamps with suitable reflectors. “The question of artificial lighting is of special importance at the present time when night work is general, and common in mines. Notwithstanding the important bearing which good eyesight must have upon output, the question is not today receiving adequate attention at the hands of those whose duty it is to obtain this output. Bad lighting affects output unfavorably, not only by making good and rapid work more difficult, but also by causing headaches and other effects of eye-strain. Incidence of accidents due to poor lighting conditions and glare at the eyes of the driver operating vehicles and HEMMs has also increased in recent past. Instance have come under the notice of this Directorate, of headaches and eye-strain resulting from (a) inadequate light, both artificial and natural; (b) artificial light, adequate in amount, but so placed as to throw a glare on the eyes of the workers; (c) employment of workers, whose eyesight should be aided by suitable glasses, to carry out fine work without first testing their eyesight.” In view of the conditions prevailing at the mines and their effects on health and safety of the persons employed therein, it is imperative to re-examine the issue of lighting in the perspective of advancement made in Lighting and Photometry DGMS Annual Report, 2009 158 that need to be applied and implemented for better work environment and safety in mines. 1.1 BACKGROUND :- Under regulation 151 – General Lighting, of the Coal Mines Regulations, 1957, the adequate arrangements for providing lighting at various places both on surface as well as belowground workings of a mine have been specified. Provisions to prevent glare or eyestrain, accidental damage and Lighting Fixture to be in compliance with the Indian Electricity Rules 1956 have been specified (Regulation 152). A Technical Committee on mining standards was appointed by the Government of India which submitted its report on Standards of Lighting in Mines in 1963. Based on the recommendations of the Committee, a technical circular no. 14 of 1964 was issued from this Directorate in which the standards of lighting for underground work places, flood lighting in depillaring areas, individuals lights, importance of lighting and eye strain due to lighting were described in details. The Standard of Lighting for Opencast Mines were also prescribed vides Government Notification No. GSR-804 dated 18.06.1975 for Opencast Coal Mines and vide GSR No. 829 dated 18.06.1975 for Metalliferous Opencast Mines. Various other requirement of lighting in depillaring areas in coal mines vide Technical Circular No. 42 of 1961, Flood Lighting in depillaring areas in first degree gassy seam vide Technical Circular No.36 of 1969 have also been notified. In the standards prescribed by the notifications mentioned above, the work place lighting requirements have been mentioned. The characteristics and parameters of the luminaries required to provide the desired level of illuminations need to be defined and specified. The lighting requirements of stationery and mobile equipment signal lighting, traffic lights and many other lighting parameters also need to be looked into. 2.0 Technology Advancement The lighting technology has advanced manifold and many lighting systems including intelligent lighting system have been developed which are not only energy efficient but also has long life of its lamps and heat sink devices. The modern lighting systems works on low voltage low current ratings and gives output more than the existing and old light fixtures like high pressure sodium vapour lamp or gas discharge systems of lights. Glaring on the eyes of the operators and eye strains are another area of concern which lead to accidents and failures resulting in loss of lives and equipment. In number of cases, the design of the lights and its fixtures were defective and in many other cases their uses were faulty. In this context, it is essential to study and investigate the lighting parameters provided by the Luminaire and develop a standard based on such investigations. The life of the lights not only depends on its design and output but also on the conditions and environment in which they are used. The Dust, water, water vapour, gas, heat, shock, noise and vibrations are the primary factors that need to be taken into considerations while designing lighting systems for specified use at specified places. The Original Lights on-boards mobile machinery are designed for a particular working conditions but during use in mines, the conditions change from mine to mine and mineral to mineral due to variations in the conditions, methods and the requirements thereon. Thus the light provided by OEM fits in properly in one mining system DGMS Annual Report, 2009 159 whereas becomes unfit in another. The placement of light sources also plays an important role on the desired level of lighting at specified location. A number of meetings and discussion have been held in this Directorate with the manufacturers and users of lighting systems in miners and have also seen during the course of inspections and enquires into accidents, that it is essential to focus our attention again on this subject and generate data from standardization of latest lighting systems and features which are required for mines and oilfields. Under this varying scenario, it becomes inevitable to ensure that :- (i) The design of light source and its technical parameters. (ii) The spectral distribution of the light output with the type of reflector and diffuser in use, (iii) The working conditions and the environment in which they are to be used; are clearly specified by the manufactures and should fulfill the requirements of the users. 3.0 DEFINITIONS/TERMS OF PHOTOMETRY AND IMPORTANT FACTORS Luminaries The complete lighting assembly, less the support assembly. For purposes of determining total light output from a luminaries, lighting assemblies which include multiple unshielded or partially shielded lamps on a single pole or standard shall be considered as a single unit. Lumen (unit) The lumen (symbol: lm) is the SI unit of luminous flux, a measure of the perceived power of light. Luminous flux differs from radiant flux, the measure of the total power of light emitted, in that luminous flux is adjusted to reflect the varying sensitivity of the human eye to different wave lengths of light. The lumen is defined in relation to the candela by 1 lm = cd. sr = 1 lx. m 2 That is, a light source that uniformly radiates one candela in all directions radiates a total of 4π lumens. If the source were partially covered by an ideal absorbing hemisphere, that system would radiate half as much luminous flux – only 2π lumens. The luminous intensity would still be one candela in those directions that are not obscured. Explanation If a light source emits one candela of luminous intensity uniformly across a solid angle of one steradian, its total luminous flux emitted into that angle is one lumen. Alternatively, an isotropic one-candela light sources emits a total luminous flux of exactly 4π lumens. The lumen can be thought of casually as a measure of the total “amount” of visible light in some defined beam or angle, or emitted from some source. DGMS Annual Report, 2009 160 A standard 120 V, 100 watt incandescent light bulb emits 1500–1700 lumens, while a standard 230 V model emits 1200–1400 lm. A 23 watt compact fluorescent lamp emits about 1500 lm. The number of lumens produced per watt of power consumed is the wall-plug luminous efficacy of the source. Difference between lumens and lux The difference between the units lumen and lux is that the lux takes into account the area over which the luminous flux is spread. A flux of 1000 lumens, concentrated into an area of one square meter, lights up that square meter with an luminance of 1000 lux. The same 1000 lumens, spread out over ten square meters, produce a dimmer luminance of only 100 lux. Achieving an luminance of 500 lux might be possible in a home kitchen with a single fluorescent light fixture with an output of 12000 lumens. To light a factor floor with dozens of times the area of the kitchen would require dozens of such fixtures. Thus, lighting a larger area to the same level of lux requires a greater number of lumens. Luminance It is the total amount of visible light illuminating (incident upon) a point on a surface from all directions above the surface. This “surface” can be a physical surface or an imaginary plane. Therefore luminance is equivalent to irradiance weighted with the response curve of the human eye. Standard unit for luminance is Lux (lx), which is lumen per square meter (lm/m 2 ). 1 lx = 10.764 fc Footcandle : fc Horizontal luminance The measure of brightness from a light source, usually measured in footcandles or lumens, which is taken through a light meter‟s sensor at a horizontal position on a horizontal surface. Vertical luminance The measure of brightness from a light source, usually measured in footcandles or lumens, which is taken through a light meter‟s sensor at a vertical position on a vertical surface. Uniformity Ratio It describes the uniformity of light levels across an area. This may be expressed as a ratio of average to minimum or it may be expressed as a ratio of maximum to minimum level of illumination for a given area. Example :- U. ratio max. to min. = 4:1 for the given area, the lowest level of illumination (1) should be no less than ¼ or “4 times less” than the maximum (4) level of illumination. The maximum brightness contrast of juxtaposed surfaces in the normal visual field should be preferably not greater than 20 to 1; that is to say, the darkest part of the DGMS Annual Report, 2009 161 working space observed should have brightness preferably not less than one-twentieth of that of the brightest part. If strictly local lighting is used without adequate general illumination of the workplace, the figure for brightness contrast will greatly exceed the standard given above and cause server eye-strain and increases accident hazard. When the local lighting is used there must be employed in addition a moderate intensity of overhead lighting uniformly distributed. Standard of Distribution Lamps should be so installed in regard to height, spacing, reflectors or other accessories, as to secure a good distribution of light on the work area, avoiding objectionable shadows and sharp contrast of intensity. The illumination on the working plane should be as uniform as possible. The variation range of illumination, that is to say the ratio of the maximum illumination to the minimum illumination, is a measure of the distribution of light and should preferably be less than 3 to 1 and not greater than 4 to 1, as relating to the machinery or work benches as the case may be. As relating to machinery and adjoining passageways the range may, of course, be much wider but should preferably not exceed 20 to 1. Direct Illumination Illumination resulting from light emitted directly from the lamp, off of the reflector or reflector diffuser, or through the refractor or diffuser lens, of a luminaries. Flood or Spotlight Any light fixture or lamp that incorporates a reflector or a refractor with a diffusing glass envelop to concentrate the light output into a directed beam in a particular direction. Lighting Fixture The assembly that houses the lamp or lamps and can include all or some of the following parts. A housing, a mounting bracket or pole socket, a lamp holder, a ballast, a reflector or mirror, and/or a refractor or lens. Full Cut off Light Fixture A luminaire light distribution where no light is emitted above the horizontal, and where the intensity at 80 degrees from nadir is no greater than 100 candela per 1000 lamp lumens. Fully Shielded Light Fixture A lighting fixture constructed in such a manner, that all light emitted by the fixture, either directly from the lamp or a diffusing element, or indirectly by reflection or refraction from any part of the luminaire, is projected below the horizontal as DGMS Annual Report, 2009 162 determined by photometric test or certified by the manufacturer. Any structural part of the light fixture providing this shielding must be permanently affixed. Height of Luminaire The height of a luminaire shall be vertical distance from the ground directly below the centerline of the luminaire to the lowest direct-light-emitting part of the luminaire. Glare The sensation produced by a bright source within the visual field that is sufficiently brighter than the level to which the eyes are adapted to cause annoyance, discomfort, or less in visual performance and visibility. Glare is often the result of excessive contrast between bright and dark areas in the field of view. For example, glare can be associated with directly viewing the filament of an sunshield or badly sunshield light. Light shining into the eyes of pedestrians and drivers can obscure night vision for up an hour after exposure. Caused by high contrast between light and dark areas, glare can also made it difficult for the human eye to adjust to the differences in brightness. Glare is particularly an issue in road safety, as bright and/or badly shielded lights around roads may partially blind drivers or pedestrians unexpectedly, and contribute to accidents. Glare can also result in reduced contrast, due to light scattering in the eye by excessive brightness, or to reflection of light from dark areas in the field of vision, with luminance, similar to the background luminance. This kind of glare is a particular instance of disability glare, called veiling glare. Glare can be categorized into different types. Blinding glare describes effects such as that caused by staring into the Sun. It is completely blinding and leaves temporary or permanent vision deficiencies. Disability glare describes effects such as being blinded by oncoming car lights, or light scattering in fog or in the eye, reducing contrast, as well as reflections from print and other dark areas that render them bright, with significant reduction in sight capabilities. Discomfort glare does not typically cause a dangerous situation in itself, though it is annoying an irritating at best. It can potentially cause fatigue if experienced over extended period. Light clutter Light clutter refers to excessive groupings of lights. Groupings of lights may generate confusion, distract from obstacles (including those that then may be intended to illuminate), and potentially cause accidents. Clutter is particularly noticeable on roads where the street lights are badly designed, or where brightly lit advertising surrounds the roadways. Depending on the motives o the persons or organizations who installed the lights, their placement and design may even be intended to distract DGMS Annual Report, 2009 163 drivers, and can contribute to accidents. Clutter may also present a hazard in the aviation environment if aviation safety lighting must complete for pilot attention with non-relevant lighting. For instance, runway lighting may be confused with an array of suburban commercial lighting and aircraft collision avoidance lights may be confused with ground lights. Light Pollution Any adverse effect of man-made light. Light Trespass Light falling where it is not wanted or needed, typically across property boundaries. 4.0 FACTORS AFFECTING STANDARDS OF ILLUMINATION Light level standards are affected by light quantity and quality desired, fixture efficiency and other applicable factors. Quantity of light or the light output and light levels is measured in lumens, lux and foot-candles. Initial Lumens/Foot-candles reflect the amount of light produced by a lamp when it is installed. Supply voltage variations, lamp‟s interaction with the ballast and dirt build up (Luminaire Dirt Depreciation) reduce the produced amount of light. Lessening of light output over time, while continuing to consume the same energy amounts (Lamps Lumen Depreciation) also reduces the light levels of the lamp and waists energy. Maintained Lumens/Foot-candles show the light level after light loss factors are taken into account over a period of time. Mean Lumens show the average light output over the lamp‟s lifetime. When addressing lighting standards a provision for the light quantity depreciation over time to due to multiple factors should be made. Quality of light depends on the brightness, distribution and light color. Photometric brightness (Luminance) is the amount of light leaving the lamp or reflecting from a surface. It is measured in foot lamberts, candles/sq. ft. and candelas/square meter (metric). Brightness can produce levels of glare if not contained properly. Every fixture has a Visual Comfort Probability (VCP) rating that reflects its levels of visual comfort. Glare can severely interface with visual comfort. High brightness ratios produce high contrast and can also create a visual fatigue during “transient adaptation”, which is the adaptation process of the eye when brightness changes. Light color depends on the visible light spectrum and the wavelengths composition of the lamp light (Spectral power distribution), the color of the light the lamp produces DGMS Annual Report, 2009 164 (Color temperature measured in Kelvin), the way the light source makes the color appear to human eyes and how well subtle variations in color shades are revealed (Color rendering - Color Rendering Index from 0-100). The higher the CRI is, the better the color rendition appears. An inappropriate color rendition can deceive the eye and supply it with wrong information. Lamp examples :- Metal Halide Lamps are High Intensity Discharge Lamps (HID) and have high efficiency and good color rendition. These lamps are used in stadiums, warehouses and industrial settings. High Pressure Sodium Lamps (HPS) are the most efficient of the HID family. Their color rendition, however, is not as good as the rendition of Metal Halide Lamps. HPS lamps are often used for street illumination. Fixture efficiency is affected by two factors. The first factor is the amount of power (watts W) required for the fixture to work at any given time and the amount of light leaving the fixture (Electrical Efficiency). The second is how much light will be produced by the fixture and how much of it will be task efficient (Fixture Efficiency). An inefficient fixture can use the same amount of energy as an efficient one while producing less light. 5.0 Other Criteria Affecting Standards Illumination Activity level in the area can change the requirement of light quantity and quality depending on the function that takes place. Visual acuity is the ability to detect a different aspect of detail. Areas that require high detail differentiation may require high visual acuity. Excessive brightness or insufficient light can hinder visual acuity. High Light Levels and vision. At high light levels absolute sensitivity decreases, contrast threshold increases, the eyes switch to photonic (cone vision) vision. Object recognition depends on the ability of the eye to discriminate differences in illumination within the object and against its environment, not on how bright the scene is. 6.0 Effects of Lighting on Human Health and Psychology. Medical research on the effect of excessive light on the human body suggests that a variety of adverse health effects may be caused by light pollution or excessive light exposure, and some lighting design textbooks use human health as an explicit criterion for proper lighting. Health effects of over-illumination or improper spectral composition of light may include: increased headache incidence, worker fatigue, DGMS Annual Report, 2009 165 medically defined stress, decrease in sexual function and increase in anxiety. Common levels of fluorescent lighting in offices are sufficient to elevate blood pressure by about eight points. There is some evidence that lengthy daily exposure to moderately high lighting leads to diminished sexual performance. Specifically within the USA, there is evidence that levels of light in most office environments leads to increased stress as well as increased worker errors. The case against light pollution is strengthened by a range of studies on health effects, suggesting that excess light may induce loss in visual acuity, hypertension, headaches and increased incidence of carcinoma. Where objective measurement is desired, light levels can be quantified by field measurement or mathematical modeling, with results typically displayed as an isophote map or light contour map. It is, therefore, recommended that Manger of every mien should prepare, update and maintain Lighting Plan :- (i) Indicating the location of the places, and the type of illuminating devices, fixtures, lamps, supports, reflectors, and other devices. (ii) Description of the illuminating devices, fixtures, lamps, supports, reflectors, and other devices and the description may include, but is not limited to, catalog cuts by manufactures and drawings (including sections where required). (iii) Indicating photometric data, such as that furnished by manufactures or similar showing the angle of cut off or light emissions. (iv) Showing the required and exiting level of luminance at various places. The Mine Management shall additionally have certified reports of tests of illumination conducted by recognized testing laboratory. 7.0 General Requirements of Artificial Lighting. The requirements for good illumination in mines, mills and other work places may be summarized as follows. i) Sufficient illumination should be provided for each workman irrespective of his position on the working space. ii) The lamps should be properly selected and so installed as to avoid or minimize strain on the eyes of the workmen. The type and size of lamp should be adapted to the particular location and height and class of work in question. iii) The lamps should be operated from sources of supply which will insure continuity of service and steadiness of light. iv) Adequate illumination should be provided from overhead lamps so that sharp shadows may be prevented as much as possible, and in such manner that individual lamps close to the work may be unnecessary except in special cases. DGMS Annual Report, 2009 166 v) In addition to the illumination provided by overhead lamps, individual lamps should be placed close to the work if they are absolutely necessary and in such cases the lamps should be provided with suitable opaque reflectors. These requirements may now be met by means of the new types of electric, LEDs and gas lamps. However the type of lamp should be decided based on the nature of work, work environment and the extent of ambient illumination. It is, therefore proposed that all Lighting Systems and Components in mines both on surface and belowground including oil and gas mines/fields should be of a type and standard approved in writing from the Directorate. A notification No.N-12019/2/2009/S&T(HQ)/16 dated 13 th January 2009 in this regard has been forwarded to be published in the Gazette of India and the subject matter thereof is reproduced below for information and taking necessary actions to comply with the requirement. “In exercise of the power conferred on the Chief Inspector of Mines also designated as Director General of Mines Safety under sub-regulation (3) of Regulation of 181 of the Coal Mines Regulation, 1957 and sub-regulation (1) of Regulation of 73 of the Oil Mines Regulation, 1984, I hereby declare 1 st March, 2009, as the date from which all types of lights, lighting Fixtures and systems including lights on board mobile machinery, in HEMMs, Machinery and Plants, Indicators or Signal lights to be used in mines both on surface and belowground including oil and gas mines/fields will be of such type, standard and make as approved by me by a general or special order in writing.” You are being informed in advance to take necessary steps in this regard and requested to ensure that it is implemented and complied with.

Sub:- Use of Local Methane Detector (LMD) in underground Coal Mines. Firedamp or Methane is the most important of the mine gases and has caused more loss of life in mines than any other gas. Methane or firedamp are synonymous to each other. Firedamp is a mixture of inflammable gases emitted from strata and besides methane, which is the principal constituent of mixture, contains higher hydrocarbons, carbon dioxide, nitrogen and water vapour. Methane mixed with air in certain proportions forms explosive mixtures. The approximate lower and upper limits of flammability of methane air mixtures are 5 and 14.8% of CH 4 . Firedamp explosions have been responsible for deaths of many miners throughout the history of mining. Statistical figure indicated that during the period 1901 to 2007 there had been 37 cases of explosion (major accidents/disaster) resulting in death of 1258 persons. Lots of emphasis were given since then in detection and measurement of CH 4 concentration in mine atmosphere. Methane emission at a face is affected by factors such as type of work going on at the face and machinery used, the time of observation in relation to the cycle of work at face, the rate of coal output and face advance, barometric pressure change, variation in air velocity., method of mining and roof control and geological factors. Sudden emission of methane may occur as instantaneous coal and gas outburst, sudden emission from roof or floor strata, as gas blower from the coal seam or adjacent strata. Thus, every mine having potential hazard on methane emission should have methane monitoring system installed and maintained. In this connection Regulation 145(1)(e) of Coal Mines Regulation 1957 says that – (i) If the determination of inflammable gas in any ventilating district shows the percentage of inflammable gas to exceed 1.25 percent, the supply of electric energy shall be cut-off immediately from all cables and apparatus working in the district. (ii) Again, Rule 126(4)(d) of Indian Electricity Rules, 1956 says that in any coal seam of second or third degree gassiness or in the danger zone of oil mines :- DGMS Annual Report, 2009 168 The supplied energy shall be disconnected from all apparatus (including portable & transportable apparatus) working in the vicinity of a place where inflammable gas has been detected by the lowered flame of a flame safety lamp kept and maintained in a continuous state of illumination. The apparatus shall be interlocked with controlling switch in such a manner as to disconnect power supply automatically in the event inflammable gas exceeds 1.25% at the place. Further, if an approved apparatus for automatic detection of % of inflammable gas or vapour in addition to Flame Safety Lamp is provided in any working district or place such apparatus shall be interlocked with portable or transportable equipment. Thus looking into the all above aspects and considering high production and mechanization, it is suggested to install a LMD (Local Methane Detector) which can automatically and continuously detect % inflammable gas at all mines having II/III degree gassy seams at following places :- (i) District/Faces having continuous mining machine. (ii) Return side of district/Longwall faces (iii) Return airway having Electrical motors. (iv) Main return airway. Though the power supply in a district has to be discontinued whenever the % of inflammable gas reaches 1.25, the power to the ventilating fans (auxiliary/booster) shall be so arranged that they run continuously. It is expected that al owner, agent and manger shall implement this circular with right spirit. ·|·™ a| ·| ·|| -| A century committed to the service of the nation No. DGMS (Tech)/Circular No./ 07 Dhanbad, Dated – 12/03/2009 To, Owner/Agent/Manager of all Mines. Sub:- Safe gaps between cage and landing levels in winding shaft An accident occurred in one of the coal mines when a work person was entering in to a cage at inset landing, he fell down in the shaft. The investigation revealed that the gap between the cage and the collar of the shaft at the inset landing was abnormally large which resulted in the accident. Although the gap between the cage and the landing level is governed by DGMS Annual Report, 2009 169 (a) Type of guide (b) Gap between the guide and convincible shoe/roller. (c) Place of landing such as at pit top, pit bottom or inter level insets. (d) Velocity/speed of the cage. Hence, it is recommended that in case of shaft equipped with :- (A) Rail/ Rigid guides. (i) Rail guides with shoes as connivance in cage the gap between the cage at all landing levels shall be as close as possible and not more than 50 mm. (ii) Rail guide with roller as connivance in cage/skip the gap between the cage at all landing levels shall be as close as possible and not more than 65 mm. (B) Guide Rope :- The gap between and both at top and bottom landing shall not be more than 65mm. At inter level inset for shaft less than 100 meters in depth the gap shall be not more than 75 mm and in the shaft more than 100 meters in depth the gap shall not more than 90 mm. Further a locking device between the cage and levels gate shall also be provided for safe movement of persons. Further it is essential that swing/flap decking devices may be provided where larger gaps are warranted and it shall overlap into the cage by at least 75mm. In the light of above, the managements shall ensure the recommendations are strictly complied in the interest of safety.

Sub:- System Study and Safety Audit for the purpose of eliminating the Risk of Accidents & Dangerous Occurrences. You all are aware that the incidence of accidents and dangerous occurrences are taking place in every type of mines whether small or big, organized of un-organized. Ultimately, it leads to human sufferings and loss of properties. The Directorate DGMS Annual Report, 2009 170 General of Mines Safety since its inception is trying its best to see that such occurrences do not occur and the valuable lives and properties are saved. Whenever there occurs an accident, disaster or any dangerous occurrence, an investigation is made both at the mine management as well as DGMS level. Causes of such occurrence are found out and remedial measures suggested to prevent recurrence of such accident or disaster. However, it has been observed that such preventive measures are not properly implemented nor a recheck done in other mines to see that such situation and conditions which lead to such accidents or disaster do not exist. When a mine becomes very large, this system to produce the required quantity of mineral also becomes complex and dynamic. In cast of such mines, it becomes necessary to study the systems in details with all its components and parameters to find out the detects or flaws. A single person or group of persons may not be well equipped to know the defects in the system, therefore it becomes necessary to engage such number of competent persons or experts on various subjects who can really find out the faults an suggest remedial measures. In such cases, it becomes a job of experts comprising of multi disciplines and subjects. With this objectives in view, it becomes necessary to carry out Risk assessment and Safety management studies and prepare a Safety Management Plan to ensure that the risk to injuries and loss of time and properties are eliminated and kept in control. A Technical Circular No. 13 of 2002 giving details and guidelines of such studies have already been circulated in the past but the progress made on this issue in mineral and not encouraging. Safety Audit is an integrated component of Risk Assessment and Safety Management, which is required to be undertaken every year and on occurrence of every accident or dangerous occurrence. However, it is also required that the Team which conducts such System Study and Safety Audit should comprise of eminent persons from various fields of operations and are kept updated about the latest tools and technique prevailing in the industry not only in India but world over. It has been observed many a times that a single person retired from the Industry conducts the safety audit and prepares the report entirely based on his experience and exposure without bringing in any new facts or instrument to deal with certain difficult situation and thus such studies do not yield any tangible results. Therefore, it is recommended that :- i) DGMS recognized Service Providers may be engaged is System Study and Safety Audit work to be under taken at any mine. ii) Such Third Party System Study and Safety Audit (SYS-SA) should be conducted at least once in every year, after every major accident or disaster or dangerous occurrence, before implementation of any new technology or use of any new system or machinery in the mine. iii) Such Study may be subject-wise as well as an Integrated Report of the mine incorporating all subjects such as mining, mechanical, electrical, personal, occupational Health & Hygiene, and any other subject applicable to the mine and the system prevailing or to be used therein. DGMS Annual Report, 2009 171 iv) The Study Report should be discussed in a Tripartite Forum at Mine Level, Area Level and also at Company Level to know the high risk areas and implement the preventive measure plans so that the efforts are directed to yield desired results in timely and sustained manner. v) One of the Inspective Officers from every discipline from DGMS should also be involved in such System Study and Safety Audit program to contribute and arrive at certain valuable decision. vi) Annual System Study and Safety Audit Report of every mine after finalization in the Company should be submitted to DGMS for information and suggestion. vii) The Action Taken Report on the System Study and Safety Audit Report should also be prepared and submitted to the Company as well as to DGMS including the Trade Unions having major or prominent representation in the mine. Risk Reduction Program (RRP) is an ongoing process to achieve Zero Harm Status of Safety in any mien and it is expected that all the persons, organizations, unions, agencies involved directly or indirectly in mining and allied business would cooperate and help achieve this goal of the DGMS and all mining Companies.

Sub:- Standards Composition and properties required for Resin Capsules to be used as grouting material for Roof Bolting in Mines. 1.0 BACKGROUND As soon as the roof in coal seam is exposed, the immediate roof starts dilating and getting detached from the overlying layers of roof strata causing it to fail if not supported properly. Roof Bolts are therefore being used as common support in underground mines all over the world along with the cement or resin grout to reinforce the strata and provide adequate support in the excavation. It is highly desired that the roof bolts once installed should immediately start taking load of the roof strata and prevent dilation so as to eliminate changes of roof fall. Resin Grout is a very effective material which sets very fast and prevents roof dilation. Although rapid set cement capsules are also being used as grout in roof bolting, but its setting time and time to provide reinforcement in the strata is too long to arrest the roof dilation. During impending loading on the roof bolts due to stressing of the strata DGMS Annual Report, 2009 173 also cement grout provides less resistance than the resin grout because resin has higher strengths than the cement grout. It is, therefore necessary to have a minimum standard required for resin grout to provide desired result and fulfill the objectives to provide support in the mines. The matter was discussed in this Directorate with the scientists from Central Institute of Mining and Fuel Research (CIMFR), Manufactures and the Users. The following Standard and Parameters have been fixed as the minimum requirements for the Resin Capsules to be used in Mines after getting approval from this Directorate. 2.0 STANDARD PARAMETERS & CHEMICAL COMPOSITION (a) Physical Condition :- Physical Condition of the resin capsule is an essential property for quality evaluation. The product performance depends upon the condition of the cartridges and their packaging shape & size and stiffness. The resin capsule shall have following properties: Sl. No. Parameters Acceptable Limits 1 Physical Condition Crimping – Proper Crimping at ends to prevent leakage Hardening of the product – No hardening Shape & Size – To be in shape and specified size Pass Pass Pass 2. Straightness : The cartridges should be straight enough and not loose and too flexible to be difficult to push inside the hole Pass 3 Fragileness Test of the double chamber Poly-tube Pass (b) Get Time and Setting Time : The performance and workability of the resin capsule depend on the gel time and setting time. Gel time plays an important role in getting Physico-mechanical, properties of the resin matrix. The Gel time is defined as the period during which a resin can be mixed with no appreciable change in viscosity, i.e, before it begins to turn from fluid to Gel. Similarly, setting time is the period, in addition to gel time that is required for the resin to turn from Gel to Solid and attain enough strength. 1. Gel Time Fast Set Medium Set Slow Set (In Seconds) 20±5 45±5 95±5 2. Setting Time Fast Set Medium Set Slow Set (In Seconds) 10±2 12±2 20±2 DGMS Annual Report, 2009 174 Note :- Resin Capsules having different Gel and Setting Times may be manufactured and supplied for different applications as required by the User, but the capsule should have valid approval and the gel & setting times especially superscripted on the capsule. (c) Viscosity :- Resin matrix should be of suitable viscosity and flow which is necessary for proper mixing and grouping of the bolts. Viscosity of the resin matrix should not be too less to flow out of the hole and should not be too high to difficult to insert the MS steel bolt. 1 Viscosity (in cps) 40,000 (mins) and 60,000 (max) (d) Acid Value :- Acid value of the resin matrix is the presence of free acid available in the system. The availability of more quantity of free acid in the resin system will enchange the rusting characteristics of the MS Bolt. This may lead to release of MS bolt from the resin grouting material. Therefore it is necessary to keep the acid level in the resin matrix below the critical level which should not cause any damage to the MS Bolt. 1 Acid value (in mg of KOH/g) 8±2 (e) Reaction Temperatures :- When catalyst (Hardener) is mixed with resin matrix, polymerization of the resin gets started. The reaction is exothermic and heat is generated in the resin system. The reaction temperature should not rise too high to get burning of the material. It is also observed that above 60 0 C, physic-mechanical properties of the product get affected and brittleness in the casted resin is developed which reduces the strength. In India variation of ambient temperature is very high. Therefore product should be thermally stable when stored in low and high temperature for better shelf life and workability in the underground mines. 1 Reaction Temperature ( O C) Not More than 60 0 C 2 Thermal Stability At 50 0 C for one hour At 45 0 C for one hour No physical & Chemical Change No physical & Chemical Change (f) Water Resistance Casted resin should not absorb water when immersed in water. Absorption of water develops micro-cracks in the resin that reduces the bonding properties and other physic-mechanical properties in the resin system. 1 Water absorption (7 days water 0.01 % (max) DGMS Annual Report, 2009 175 immersion) 2.1 Physico-Mechanical Properties The Physico-Mechanical Properties of the resin capsule shall conform to the following parameters and values : 1. Compressive Strength 30 minutes 24 hrs 30.0 MPa (Min.) 80.0 MPa (Min.) 2. Bond Strength Test 30 minutes 24 hrs 10.0 Tonnes 20.0 Tonnes 3. Shot Encapsulation Test (Tonne) 30 minutes 24 hrs 12.0 Tonnes 20.0 Tonnes 4 System Stiffness 20 KN/mm – System stiffness between 50 to 150 KN 5 Creep Test Fast set at 5 KN for 25 minutes Slow set at 20 KN for 25 minutes (%) 0.12 (Max) 0.12 (Max) 6 Shear Test 30 minutes 24 hrs 7.50 Tonnes 15.0 Tonnes 7 Elastic Modulus Test 24 Hrs 11.0 GPa 8 Shrinkage test At 30±2 0 C & 65 % humidity 24 hrs 7 days 0.01 1% (Max.) 0.01 1% (Max.) 2.2 Other Properties : 1 Flammability Test Reaction of resin system is exothermic and methane with coal dust is likely to be present in underground mines. If reaction temperature reaches above 120 0 C by any reason, resin matrix should not catch fire. Product should be of very low flammability. The flame should cease within 10 second after removal of the product from burner after 30 second. NOTE :- The test will be applicable within three month of issuing of this guidelines. Non-Flammable 2 Toxicity Product should not affect skin, eyes and other organs of human being during application of the product.

Sub:- Standards Composition and Properties of Roof Bolts to be used in Mines. Roof Bolts are now widely being used in coal mines as well as non-coal mines to provide support in the mine workings. The steel used for the roof bolts are normally from thermo mechanically treated (TMT) rebar manufactured by various steel manufacturing companies. During the testing of some of the samples of roof bolts manufactured by some companies, it has been found that the roof bolt itself had failed and broken at 8 to 10 Tonnes Tensile Load against the requirement of at least 16 Tonnes. In some cases, the failure was brittle and sudden which indicate that the quality of steel from which the roof bolts are made, is not of the required strength and properties. The Nuts, Threads and bearing plates had also failed at very low loads. If such types of roof bolts are used in the mines, it will not provide the desired resistance and support in the strata and would lead to premature fall of roof and sides leading to accidents and fatalities. In view of the above, the matter was discussed in detail in this Directorate and it was decided to evolve a minimum standard that is required for the roof bolt and its accessories to comply with, so that the desired support resistance is provided by the roof bolts in the mine workings. A meeting was convened with the Scientists from Central Institute of Mining and Fuel Research (CIMFR), and the Officers of DGMS. The issues related to Standard and Parameters that is required for the roof bolts were discussed in detail and the following Standard and Parameters have been fixed as the minimum requirements for the Roof Bolts and its accessories to be used in Mines after getting approval from this Directorate:- 1.0 Physical Properties :- Roof Bolts (a) Shape & Size :- The Roof bolt shall be of MS Steel or TMT Rebar having circular cross-section with ribs on circumferential region.

Sub:- Provisions of Rear Vision System in Equipments Several accidents have occurred in opencast mines while reversing of equipment especially in dumpers/tippers. The manufactures provide only audio visual alarm and rear view mirrors in the equipments. Although the Audio Alarm gives warning to the DGMS Annual Report, 2009 181 work persons, the drivers/operators does not have a clear view of the rear side of equipment. It is a practice in mines that the operator takes the assistance of a spotter while reversing. The spotters are exposed to danger of being crushed by equipment. The audio visual alarm warning at times may not provide sufficient time for the spotter and others to escape from the site and incidents/accidents takes place. To avoid above kind of situations, it is strongly recommended that REAR VISION SYSTEM may be installed in the equipment especially in dumper/tippers. The system shall be provided with a monitor which can be installed inside the cabin of the operator and an automatic switch on the reverse gear actuates ultra low light camera with sufficient number of infra-red LEDS installed at rear of the vehicle which provide picture in nearly pitch dark and poor weather conditions and a clear and sharp picture is displayed on the monitor. The camera shall be housed in a fully water proof case which is shock and vibration resistance and suitable for high pressure washing. The two components shall be connected by a suitable detachable cable with water proof joints. It may be noted that the above provisions is in addition to audio visual alarm and rear view mirrors which is already provided with the equipments/ It is recommended that in the interest of safety, necessary action shall be taken to provide Rear Vision System in equipments so as to eliminate the chances of accidents while reversing.

Telemonitoring System for continuous monitoring of inflammable/toxic gases, air velocity, etc., are not new to the underground coal mines of the country. Such systems have been in use in some of the highly mechanized underground coal mines with history of high gassiness and proneness to spontaneous heating. This scenario is however slowly changing and more and more such systems are now being introduced in all such mines as an effective means to detecting inflammable/noxious gases and spontaneous heating in nascent stages, thereby enabling suitable mitigating measures to ward of likely disasters. However, recent inspections of a large number of such installations by the officers of this Directorate revealed the dismal state of affairs as regards their installation and maintenance. Invariably, the system were found to be either faulty of non-working, thereby defeating the very purpose of their installation in difficult working situations. It was also revealed that there was no reliable mechanism to ensure the health of such installed systems on a long-term basis. The gravity of the situation was intense because of the working of such faulty system. In mines with a potential to give DGMS Annual Report, 2009 182 misleading information on gas concentrations, etc. The consequences of such misleading information in potentially grave situation in difficult mining conditions do not need any elaboration. As such, the matter was thoroughly deliberated upon in a tripartite technical workshop held on 9 th of October, 2009 in this Directorate at Dhanbad, attended by the representatives of the management, manufacturers and this Directorate for resolving various connected issues, and the following collective decisions were arrived at. 1.0 The basic components of a Telemonitoring system :- A telemonitoring system for use in underground mines shall consist of the following as essential basic components. Various sensors. A display unit. Surface monitoring system for display, storage and retrieval of readings and also a warning system. Power supply system. Electrical power tripping arrangements. Connected data transmission cables. 2.0 Underground display unit of the telemonitoring system :- Proper display arrangements shall be provided at surface and also in the underground installation at the out-stations and with sensors. The display shall be clearly visible from a reasonable distance. The display system shall also be provided with a colour changing/blinking arrangements for indicating any recording of an environmental parameter above the pre-set value. 3.0 Various parameters of the sensors as records (a) minimum operating life of sensors, (b) working limits of temperature & relative humidity, (c) calibration including the maximum permissible deviation when tested with standard gases, frequency of calibration, availability of standard gases and various records to be maintained thereof :- a) The minimum operating life of the sensors shall be as follows. Sensors Type Operating Life CH 4 (Infrared) 5 years. CH 4 (Catalytic) 2 years. CH 4 (Elecro-chemical) 2 years. CO 2 years O 2 1 year b) Workings limits of temperature - Not more than 50 C Workings limits of Relative Humidity - Upto 100% c) Calibration DGMS Annual Report, 2009 183 (i) The deviation of the measured gas concentration shall not be more than 3% for all sensor types when tested with standard gases. (ii) The maximum interval of calibration of sensors shall not exceed three months, alternating between the OEM and the users. However, The OEM shall examine the complete telemonitoring system in totally at least once every six months. (iii) Adequate samples of standard gases shall be always made available at the concerned mine. (iv) Proper records of calibrations done, duly singed by the designated officer and the Manager for the purpose, shall be maintained at the mine. 4.0 Use of the approved system in the mines :- Any sale/purchase of the continuous telemonitoring system shall be in conformity with the approved system in respect of all the basic components as mentioned above. 5.0 The minimum required power back up with the telemonitoring system:- The minimum required power backup in the event of disruption of the main electrical power supply shall be for a period of four hours. 6.0 Alarm system in the telemonitoring system :- The minimum intensity of the audio part of the audio-visual alarm provided with the telemonitoring system shall be 90 dB(A). In the underground workings, at least one audio alarm shall be provided with every out-station of the telemonitoring system. 7.0 Electrical interlocking of the telemonitoring system :- The tripping circuit of the telemonitoring system shall be electrically interlocked with the power supply system of the connected workings so as to cut off power supply when the concentration of inflammable gases measured exceeds a preset value. 8.0 Recording of telemonitoring events on surface :- Every telemonitoring installation shall be provided with an arrangements for recording and retrieving data on a continuous basis. 9.0 Maintenance of the telemonitoring system :- Every telemonitoring system shall be associated with a comprehensive Annual Maintenance Contract (AMC) with the OEM to cover both for spares and services. The period of AMC shall be not less than 5 years. The maximum response time for attending to any maintenance related problems shall not be more than 24 hours. It is therefore, requested that the above mutually agreed recommendations are implemented strictly in respect of all telemonitoring system installed in underground coal mines. For ensuring efficient working of such systems on a long-term basic, the ISO shall have suitable time bound action plans and shall rigorously follow-up with the same.

Sub:- Use and care of Local Methane Detectors in Underground Coal Mines. Of recent, Local Methane Detectors (LMD) are being installed in underground coal mines for monitoring the make of inflammable gases and for imitating suitable mitigating measures well in advance before the concentration assumed dangerous proportions. In this connection, a DGMS (Tech) Circular No. 6 of 2009 was issued to the industry covering a few aspect of the installation and operation of the LMDs in the mines. However, recent inspection of such installation by the officers of this Directorate revealed that such installation are not in a position to deliver the purpose for which they were installed, on account of several reason. It was also revealed that the aforementioned DGMS (Tech) Circular No. 6 of 2009 was also not being followed in the right spirit. This matter was viewed on a serious note and a technical workshop was organized in this Directorate at Dhanbad on the 8 th of September, 2009 for extensive deliberations on the above subject. As a result of the deliberations, the following recommendations were arrived at. 1.0 Various components which make an LMD :- An LMD shall include the following as essential basic components. A CH 4 sensor unit An FLP housing for the electrical circuits and a display unit for the detected and measured CH 4 concentration. The FLP housing may be integrated with the sensor unit.

An audio-visual warning alarm unit. 2.0 The defined parameters of the life of the sensor used in the LMDs and their operating limits in terms of temperature and relative humidity :- The minimum life of a sensor used in the LMDs shall be at least three years. The sensor shall operate satisfactorily at a temperature upto 50 0 C and a relative humidity of upto 100%. 3.0 Place of installation of the LMD :- The LMD shall be installed in the main district ventilation return airway of the district, as close as practically possible to a well supported roof as may facilitate clear observation of the display unit. DGMS Annual Report, 2009 185 4.0 The type of electrical interlinking necessary with the LMD :- Every LMD shall have a provision of a suitable outlet for coupling with the electrical supply system of the ventilating district by way of approved cables, connectors and other electrical accessories. The tripping circuit of the LMD shall be electrically interlocked with the power supply system of the connected workings so as to cut off power supply when the concentration of the measured inflammables gases exceeds a preset value. 5.0 The minimum required power back up with the LMD :- The minimum required power backup in the event of disruption of the main electrical power supply shall be for a period of 60 minutes, to be provided by a battery preferably of a rechargeable type and with a minimum life of 12 months from the date of dispatch of the battery. Wherever there is no battery backup, the same shall be incorporated within a period of six months. 6.0 The levels of Audio-visual alarm to be provided in terms of intensity :- The audio level of the audio-visual alarm shall be at least 85 dB (A). The visual alarm shall be consisting of a cluster of LEDs or other suitable arrangements as may be distinctly visible from at least two opposite directions. 7.0 The frequency of calibration of sensors and other components :- The maximum interval of calibration of the sensors shall not exceed three months, alternating between the OEM and the user. All calibrations shall be done by the OEM. 8.0 The type of back-up service required for proper up keep of the system viz-a- viz reliability :- The OEM examine the LMD in totally at least once every six months. It is therefore, requested that the above recommendations are implemented in true spirit in respect of all installations of LMD in underground coal mines. Also, you are requested to utilize the mechanism of the Internal Safety organizations (ISO) of your respective companies to have a time bound action plan to ensure that installed LMDs are always maintained functional and in reliable conditions.

Dust Suppression/Prevention device in drilling and boring equipment. No. DGMS/S&T/Tech.Cir. (Approval No./ 02 Dhanbad, Dated – 18 th June 2009 To, All the Owner/Agent/Manager & Manufacturer Sub:- Standard Composition and Properties required for Cement Capsules to be used as grouting material in Roof Bolting in Mines. 1.0 BACKGROUND In early years in mining, timber was the primary material being used as supports of the underground excavations in belowground mines. In those days, good quality treated timbers were available in sample and was also being imported from Burma (Now Myanmar). Increased exploitation of forest resources and rampant deforestation resulted in scarcity of timbers even for house hold uses. Steel then came into market DGMS Annual Report, 2009 217 as substitute and is invariably used in the industry including domestic uses. Cement is equally important material to be used along with the steel in industries and infrastructure fields. Roof Bolts are now being used as common support in underground mines all over the world along with the cement or resin grout to reinforce the strata and provide adequate support in the excavation. Since past ten to fifteen years, cement grouted roof bolts have almost replaced the timber supports in coal mines in India. It is highly desired that the roof bolts once installed should immediately start taking load of the roof strata and prevent dilation so as to eliminate chances of roof fall. Quick Setting Cement Grout was the only option to provide required support resistance. Various composition were tried by adding quick setting chemicals and other re-agents in the cement composition. It was then possible to gain pull out load of about 3 Tonnes within 30 minuters and 5 Tonnes within 2 hours of installation. The Resin Grouts were also available for use in mines but it was cost prohibitive and uneconomical for Indian conditions during nineties. With the advancement of technologies and faster rates of extraction, resin capsule is now being invariably used and are now economically viable in case of mass production. However, the use of cement capsules would continue for medium and small scale productions. A number of technical circulars have been issued from this Directorate regarding load requirements, installation, testing and use of roof bolts from time to time. Technical Circular No.6 of 1996, Circular No. 3 and 6 of 1993 are highly elaborative and exclusive on the subject. In spite of the best effort put in both from the mine operators as well as from this Directorate, the results are not upto the expected level. 2.0 NECESSITY It would be pertinent to mention here the trends of fatal accidents in coal mines especially due to fall of roof and sides. The accidents data analyzed for the past fifteen to twenty years during which the full column grouted roof bolts along with cement capsules were being used, have revealed that :- (i) 38 to 40% of the fatal in coal mines are caused due to fall of roof and sides; (ii) 57 to 60% of the total below ground accidents are caused due to fall of roof and sides; and (iii) 58 to 60% of the roof fall accidents occur within 10 m of the face i.e. within the Freshly Exposed Roof Area. A number of accidents due to fall of roof have occurred within 2 to 4 hours of exposure of the roof where cement grouted roof bolts were used that failed and fell along with the failing roof of thickness varying from 0.25 to 1.2m. In many cases during the course of inspection and enquiry, it has been found that the roof bolts which were expected to take 3 Tonnes of anchorage load after 30 minutes of installation were pulled out within 1.6 to 2.4 Tonnes. The roof Bolts which were DGMS Annual Report, 2009 218 expected to take 5 Tonnes of load after 2 hours of installation were pulled down in less than 3 Tonnes. The above observations necessitated in-depth studies on this subject and to have a better system to check and monitor the quality of grout as well as the roof bolts being used in the mines. With this objective in view, it was decided in this Directorate to bring the support materials and the Steel supports under the purview of approval and testing before being used in the mines. A notification vides G.S.R. 160, dated 14 th August, 2008 and DGMS Technical Circular No. (S&T)3/703 dated 14 th August, 2008 were issued in this regard. 3.0 APPROVAL & TESTING The applicants were granted approval for field Trials and Testing based on their Tests and Performance Reports submitted along with their applications. During the period of such approval, samples were collected from the Manufactures Units and tested at the Central Institute of Mining and Fuel Research (CIMFR), Dhanbad. On receipt of the Test Reports from CIMFR, it was observed that many of the Cement Capsules manufactured by various manufactures could not pass the bare minimum requirements and had failed. The detailed information on the Tests Data of few samples is tabulated below:- Test Data No. 1 (a) Physico- Mecanical Properties Sl. No Parameters Acceptable Limit Result Conclusio n 1 Average Soaking Time 3.0 Minutes (Maximum) 2.55 Minutes Passed 2 Initial Setting Time 3.0 Minutes (Maximum) 3.30 Minutes Failed 3 Final Setting Time 15.0 Minutes (Maximum) 6.00 Minutes Passed 4 Compressive Strength gained after 30 Minutes 2 Hrs 24 Hrs 7 Days 21 Days 28 Days Minimum Compressive Strength in MPa 4.5 9.0 16.0 16.0 16.0 16.0 3.00 4.90 4.65 4.60 Failed DGMS Annual Report, 2009 219 5 Anchorage Strength after 30 Minutes 2 Hrs 24 Hrs Minimum in Tonnes 3.0 5.0 8.0 3.2 3.5 Failed (b) Chemical Properties Sl.

Thus the above composition was found unsuitable for wet or watery strata conditions. On examination of the above information, it was found that the bare minimum anchorage load of 3 and 5 Tonnes required after 30 minutes and 2 hours could not be achieved. Even the required compressive strength of 16 MPa could not be achieved after 24 hours and also after 7 days. In addition, the composition had failed in other tests. Therefore the approvals granted to such manufactured were withdrawn. 4.0 STANDARD PARAMETERS & CHEMICAL COMPOITION Based on the above observations, it was decided in this Directorate to have detailed discussions on this matter with the scientist from CIMFR who are dealing with this subject and also from the Expert on Strata Control and Rock Mechanics from Indian School of Mines University. After detailed deliberation on various issues and DGMS Annual Report, 2009 221 parameters required for the Cement Capsule, it was decided that the following parameters shall be essentially required for the Cement Capsules to be used in mines as a Grouting materials. Sr. No. Parameters Acceptable Limits 1 Average of soaking time (Minutes) 3.0 (max) 2 Initial setting time (Minutes) 3.0 (max) 3 Final setting time (Minutes) 15.0 (max) 4 Compressive Strength Gain after- 30 Minutes 2 Hrs 24 Hrs 7 Days 21 Days 28 Days Minimum in MPa 4.5 9.0 16.0 16.0 16.0 16.0 5 Anchorage Strength after 30 Minutes 2 Hrs 28 Hrs (Minimum in Tonnes) 3.0 but test will be conducted till complete failure 5.0 but test will be conducted till complete failure 12.0 but test will be conducted till complete failure (b) Chemical Properties of Cement Capsules Sr. No. Chemical Test Acceptable Limits 1 Chloride Free Chloride free cement capsule composition is essential because, presence of chloride will exchange the rusting rate of MS steel bolt grout with cement capsules. This may lead to release the MS steel bolt from the grouting material. NIL 2 Viscosity/Thyrotrophic Nature of Wetted Cement Capsules Proper Viscosity and flow of wetted cement capsule is necessary for proper grouting of the bolts. Viscosity of wetted cement capsule should not be to less to flow out of the hole and should not be too high to difficult to insert the MS steel bolt. The optimum viscosity of cement capsules will be in the range of 35,000 to 50,000 cps. 35,000 to 50,000 cps. 3 Shrinkage Test (IS:4031 (Part 10) 1988 Shrinkage of the grouted cement capsules should not be more than 0.01% at 27 ± 2 0 C and 65% humidity Less than 0.01% DGMS Annual Report, 2009 222 upto 35 days. If shrinkage is allowed than bolt with grouted material will release the surface of the hole and will fall out from the hole. 4 Calcium Oxide Calcium Oxide exchange the cementing properties of the grouting material and present in the quick set cement and other cements used in the manufacturing of the cement capsules. The optimum quantity of CaO is essential for getting the proper setting time as well as strength in the grouting material. Optimum quantity of CaO is 35%. Below the optimum it will affect the setting time and strength of the grouting material and above the optimum percentage brittle nature will develop in the grouting material. Cracks develops in the grouted material will release the bolt and become unsafe to mine environment. 30 to 35% 5. Alumina Alumina plays an important and crucial role in the initial setting, final setting and getting proper strength in the cement capsules. The quantity of alumina in the cement capsule is depends upon the quantity of high alumina cement added in the composition. Generally high alumina cement contain 35-45% alumina content and for manufacturing cement capsule of good quality and for manufacturing cement capsule of good quality about 30% high alumina cement should be added in the composition. Therefore, percentage of alumina percentage should not be less than 10% to get proper setting time as well as strength and shelf life of the grouting material. It was observed that above 25% alumina content in the cement capsules, the brittle nature of the grouted material is increased and cracks were developed in the material due to exothermic reacition. 10 0 15% 6. Iron Oxide Proper quantity of iron oxide in the cement capsules is required for getting proper performance and it should be not more than 5%. Above the optimum percentage iron oxide will enhance the brittle nature of the grouting material. 5% (Max.) 7. Magnesium Oxide Optimum quantity of magnesium will give the better result but increase in percentage will decrease the setting time but increase the brittle nature of the material which may lead to decrease in the strength of the material. MgO content. 2% (Max.) 8. Loss on Ignition Organic and other combustible material should not be more than 2% of the total mass. It is observed that DGMS Annual Report, 2009 223 water reducers, plasticizes and organic grouting material will enhance the physico- mechanical properties of the grouting material but above 2% it will give adverse effect on the grouting materials. 2% (Max.) 9. Silica Content Silica plays an important role in the cement capsules and will provide encapsulation properties as well as enhance the strength and other physico- mechanical properties of the grouted material. With high alumina strength silica gives proper binding and compressive strength to the MS bolt. Proper quantity of silica is required for getting good quality of cement capsule composition and it should not be more than 20% of the total mass. The silica should be clay free. 15 to 20% 10. Plaster of Paris It was observed that present manufactures are using plaster of Paris in place of high alumina cement. Due to POP physico- mechanical properties is below the acceptable limits and giving very poor results. Therefore, it is advised to instruct the cement capsule manufactures not to add POP and manufacture POP free cement capsules. NIL 4.1 TEST FACILITIES AT MANUFACTURER’S UNIT In order to ensure and maintain the quality of cement capsule manufactured at the manufacturing units, it shall be required to have the following apparatus & testing facilities: Sr. No. Name of Apparatus/Equipment Quantity (Nos) Capacity 1.

No. Name of Apparatus/Equipment Quantity (Nos) Capacity 1. Viscometer One 10,00,000 cps. 2 Anchorage Testing Machine One 50 Tonnes 3 Universal Compressive testing machine One 50 Tonnes 4 pH meter One 0-14 5.0 SAMPLING & TESTING In order to check the composition and required parameters during manufacture, it shall be required that the random sampling shall be collected at least 1 sample containing adequate number/quantity of cement capsules for every 10,000 pieces of cement capsule in a batch and shall be subjected to the required set of tests as prescribed at para-4.0 above and the data shall be kept recorded in a bound paged book kept for the purposes which shall be signed by the persons carrying out the test and shall also be counter-signed by the quality control officer posted at the manufacturing unit (s). 5.1 The user shall also carry out similar sampling and testing as per the apparatus/instrument kept there at their end before using, for every batch of cement capsules and keep the records in a bound paged book kept for the purpose. In case the cement capsules fall to pass the required tests at the user end, that lot of the manufactures shall not be used and intimation thereof shall be sent to this Directorate and also to the manufacturer. Manufacturers and the Users including the Test Houses, who are engaged for testing such material, are therefore requested to ensure the above mentioned Standard and Parameters before supplying and using at the mine. <><><><><><><> <><><><><> DGMS Annual Report,2009 Competency.

This also means that sufficient time was not allowed for the roof to settle before engaging persons. Thus roof fall occurred in all types of coal seams irrespective of their thickness. 6% of the fatal accidents occurred between ½ . 5.

This can be avoided by adequately training the face workers for paying more attention towards identification of bad roof and testing for its weakness and by providing temporary supports before erecting permanent support. and 11% in seams with thickness between 69m. Depth of cover: 33% of the fatal accidents accounted in depth of cover upto 100 m. 11% between 1 to 2 hours and 29% of the fatal accidents occurred beyond 2 hours of blasting operation and in 28% of cases no blasting operation was carried out. 22% in roof bolts & others and 56% in other supports. 33% in 3 to 6 m.1 hour. Thickness of seam: 40% of the fatal accidents occurred in coal seam having thickness upto 3. Time elapsed after blasting: 26% of the roof fall accidents occurred within 30 minutes of blasting operation which correlates with the operation at the time of accident as mentioned above. 32% between 0.

Operation at the time of accident: 15% of the fatal accidents occurred during loading (manual) operation. 11% each of the fatal accidents occurred during withdrawal of support. thus 38% of the accidents occurred during primary job of face preparation and manual loading. 36% in 101 to 200m. Practically roof fall accidents occurred at every place irrespective of the depth in proportion to the working plan at various depths except for depth of cover above 401m.0 m. 13% occurred during loading by machine and 20% due to other activities. Mainly face workers were involved in the accidents as they are first to approach the face and stay beneath the green roof areas for longer duration.00 hours and 7% between 6. Management factors 17. It indicates that practically all types of roof are likely to fall in absence of adequate supports. 17% of the fatal accidents due to fault of Subordinate Supervisory Staff alone. 11% in ECL.00 hours of the work. Company: Company-wise analysis indicates that 73% of roof fall accident occurred in CIL whereas 20% occurred in SCCL. Thus it is observed that roof fall occurred mainly in first shift due to more number of persons employed during day time. 15% between 41-45 years. 15.DGMS Annual Report.3m. 16.01 – 7. 15% between 5. 18. 33% of fatal accident occurred having thickness of fallen strata between 0. 18% in SECL. In 5% of cases deceased was responsible. Responsibility: 44% of the fatal accidents were caused due to fault of management and Subordinate Supervisory Staff. Fall of roof was mainly due to geological reasons such as presence of slicken sides. Thus 36% of the roof fall accidents occurred between third and fifth hours of the shift. 9% dressers and 3% shotfirer/explosive carrier.

Corrective measures: Rate of extraction has to be made faster by deploying well maintained loading machines and loss of coal in the goaf has to be minimized. A-36 . Rib of coal left as barrier between opencast working and belowground working need to be covered to prevent formation of return circuit through the cracks/fissures developed at the surface. There was a case of fire in conveyor belt of rapid loading system.2009 Not cleaning the old galleries and return airways off fallen coal and not treating thoroughly with stone dust. Fallen loose coal has to be cleaned off regularly. Sluggish ventilation in old workings and depillaring areas. Non provision of latest carbon monoxide gas detecting devices. Isolation and sectionlization stoppings have to be regularly inspected as per statute to detect early stage of spontaneous heating. Proper code of practice for prevention of fires in HEMM should be framed and implemented. There was a case of fire in drill m/c during the break down maintenance in an open cast mine.DGMS Annual Report. Not filling up the surface cracks formed due to subsidence and causing leakage of air into the sealed off areas and old workings. Reinforcement of stoppings and cleaning of return airway to prevent choking shall be done. Corrective measures: Timely action has to be initiated if active fire is known be existed behind the stoppings. Working the depillaring panel beyond the incubation period. There was a case of fire in shale debris as carbonaceous material dumped in haul road caught fire due to fire in dry vegetation. There was a case of fire in 550v cable due to three phase short circuiting at the cable joint box. Not making and maintaining the isolation stoppings as prescribed. Adequate precautions shall be taken as per statute while using flame or electric welding or repairing apparatus belowground as well as in opencast workings. Other Fires There was a case of fire in dry vegetation extended upto the old tyre stock yard of the excavation workshop. All the galleries exposed on the side of entries to the belowground workings in the seam shall be covered effectively to avoid breathing of air through those galleries. B.

Lumen (unit) The lumen (symbol: lm) is the SI unit of luminous flux. in that luminous flux is adjusted to reflect the varying sensitivity of the human eye to different wave lengths of light. its total luminous flux emitted into that angle is one lumen. The placement of light sources also plays an important role on the desired level of lighting at specified location. Explanation If a light source emits one candela of luminous intensity uniformly across a solid angle of one steradian. m2 That is. it becomes inevitable to ensure that :(i) The design of light source and its technical parameters. the measure of the total power of light emitted.0 DEFINITIONS/TERMS FACTORS Luminaries OF PHOTOMETRY AND IMPORTANT The complete lighting assembly. sr = 1 lx. are clearly specified by the manufactures and should fulfill the requirements of the users. Therefore luminance is equivalent to irradiance weighted with the response curve of the human eye. 2009 A standard 120 V. which is lumen per square meter (lm/m2).764 fc Footcandle : fc Horizontal luminance The measure of brightness from a light source. the lowest level of illumination (1) should be no less than ¼ or “4 times less” than the maximum (4) level of illumination. which is taken through a light meter‟s sensor at a horizontal position on a horizontal surface. A 23 watt compact fluorescent lamp emits about 1500 lm. Achieving an luminance of 500 lux might be possible in a home kitchen with a single fluorescent light fixture with an output of 12000 lumens.DGMS Annual Report. The number of lumens produced per watt of power consumed is the wall-plug luminous efficacy of the source. This may be expressed as a ratio of average to minimum or it may be expressed as a ratio of maximum to minimum level of illumination for a given area. To light a factor floor with dozens of times the area of the kitchen would require dozens of such fixtures. = 4:1 for the given area. Luminance It is the total amount of visible light illuminating (incident upon) a point on a surface from all directions above the surface. Standard unit for luminance is Lux (lx). Difference between lumens and lux The difference between the units lumen and lux is that the lux takes into account the area over which the luminous flux is spread. 1 lx = 10. The maximum brightness contrast of juxtaposed surfaces in the normal visual field should be preferably not greater than 20 to 1. that is to say. ratio max. 100 watt incandescent light bulb emits 1500–1700 lumens. concentrated into an area of one square meter. the darkest part of the 160 . lights up that square meter with an luminance of 1000 lux. This “surface” can be a physical surface or an imaginary plane. spread out over ten square meters. usually measured in footcandles or lumens. Example :. Vertical luminance The measure of brightness from a light source. A flux of 1000 lumens.U. produce a dimmer luminance of only 100 lux. to min. which is taken through a light meter‟s sensor at a vertical position on a vertical surface. The same 1000 lumens. while a standard 230 V model emits 1200–1400 lm. Thus. Uniformity Ratio It describes the uniformity of light levels across an area. usually measured in footcandles or lumens. lighting a larger area to the same level of lux requires a greater number of lumens. DGMS Annual Report, 2009 working space observed should have brightness preferably not less than one-twentieth of that of the brightest part. If strictly local lighting is used without adequate general illumination of the workplace, the figure for brightness contrast will greatly exceed the standard given above and cause server eye-strain and increases accident hazard. When the local lighting is used there must be employed in addition a moderate intensity of overhead lighting uniformly distributed. Standard of Distribution Lamps should be so installed in regard to height, spacing, reflectors or other accessories, as to secure a good distribution of light on the work area, avoiding objectionable shadows and sharp contrast of intensity. The illumination on the working plane should be as uniform as possible. The variation range of illumination, that is to say the ratio of the maximum illumination to the minimum illumination, is a measure of the distribution of light and should preferably be less than 3 to 1 and not greater than 4 to 1, as relating to the machinery or work benches as the case may be. As relating to machinery and adjoining passageways the range may, of course, be much wider but should preferably not exceed 20 to 1. Direct Illumination Illumination resulting from light emitted directly from the lamp, off of the reflector or reflector diffuser, or through the refractor or diffuser lens, of a luminaries. Flood or Spotlight Any light fixture or lamp that incorporates a reflector or a refractor with a diffusing glass envelop to concentrate the light output into a directed beam in a particular direction. Lighting Fixture The assembly that houses the lamp or lamps and can include all or some of the following parts. A housing, a mounting bracket or pole socket, a lamp holder, a ballast, a reflector or mirror, and/or a refractor or lens. Full Cut off Light Fixture A luminaire light distribution where no light is emitted above the horizontal, and where the intensity at 80 degrees from nadir is no greater than 100 candela per 1000 lamp lumens. Fully Shielded Light Fixture A lighting fixture constructed in such a manner, that all light emitted by the fixture, either directly from the lamp or a diffusing element, or indirectly by reflection or refraction from any part of the luminaire, is projected below the horizontal as 161 DGMS Annual Report, 2009 determined by photometric test or certified by the manufacturer. Any structural part of the light fixture providing this shielding must be permanently affixed. Height of Luminaire The height of a luminaire shall be vertical distance from the ground directly below the centerline of the luminaire to the lowest direct-light-emitting part of the luminaire. Glare The sensation produced by a bright source within the visual field that is sufficiently brighter than the level to which the eyes are adapted to cause annoyance, discomfort, or less in visual performance and visibility. Glare is often the result of excessive contrast between bright and dark areas in the field of view. For example, glare can be associated with directly viewing the filament of an sunshield or badly sunshield light. Light shining into the eyes of pedestrians and drivers can obscure night vision for up an hour after exposure. Caused by high contrast between light and dark areas, glare can also made it difficult for the human eye to adjust to the differences in brightness. Glare is particularly an issue in road safety, as bright and/or badly shielded lights around roads may partially blind drivers or pedestrians unexpectedly, and contribute to accidents. Glare can also result in reduced contrast, due to light scattering in the eye by excessive brightness, or to reflection of light from dark areas in the field of vision, with luminance, similar to the background luminance. This kind of glare is a particular instance of disability glare, called veiling glare. Glare can be categorized into different types. Blinding glare describes effects such as that caused by staring into the Sun. It is completely blinding and leaves temporary or permanent vision deficiencies. Disability glare describes effects such as being blinded by oncoming car lights, or light scattering in fog or in the eye, reducing contrast, as well as reflections from print and other dark areas that render them bright, with significant reduction in sight capabilities. Discomfort glare does not typically cause a dangerous situation in itself, though it is annoying an irritating at best. It can potentially cause fatigue if experienced over extended period. Light clutter Light clutter refers to excessive groupings of lights. Groupings of lights may generate confusion, distract from obstacles (including those that then may be intended to illuminate), and potentially cause accidents. Clutter is particularly noticeable on roads where the street lights are badly designed, or where brightly lit advertising surrounds the roadways. Depending on the motives o the persons or organizations who installed the lights, their placement and design may even be intended to distract 162 DGMS Annual Report, 2009 drivers, and can contribute to accidents. Clutter may also present a hazard in the aviation environment if aviation safety lighting must complete for pilot attention with non-relevant lighting. For instance, runway lighting may be confused with an array of suburban commercial lighting and aircraft collision avoidance lights may be confused with ground lights. Light Pollution Any adverse effect of man-made light. Light Trespass Light falling where it is not wanted or needed, typically across property boundaries. 4.0 FACTORS AFFECTING STANDARDS OF ILLUMINATION Light level standards are affected by light quantity and quality desired, fixture efficiency and other applicable factors. Quantity of light or the light output and light levels is measured in lumens, lux and foot-candles. Initial Lumens/Foot-candles reflect the amount of light produced by a lamp when it is installed. Supply voltage variations, lamp‟s interaction with the ballast and dirt build up (Luminaire Dirt Depreciation) reduce the produced amount of light. Lessening of light output over time, while continuing to consume the same energy amounts (Lamps Lumen Depreciation) also reduces the light levels of the lamp and waists energy. Maintained Lumens/Foot-candles show the light level after light loss factors are taken into account over a period of time. Mean Lumens show the average light output over the lamp‟s lifetime. When addressing lighting standards a provision for the light quantity depreciation over time to due to multiple factors should be made. Quality of light depends on the brightness, distribution and light color. Photometric brightness (Luminance) is the amount of light leaving the lamp or reflecting from a surface. It is measured in foot lamberts, candles/sq. ft. and candelas/square meter (metric). Brightness can produce levels of glare if not contained properly. Every fixture has a Visual Comfort Probability (VCP) rating that reflects its levels of visual comfort. Glare can severely interface with visual comfort. High brightness ratios produce high contrast and can also create a visual fatigue during “transient adaptation”, which is the adaptation process of the eye when brightness changes. Light color depends on the visible light spectrum and the wavelengths composition of the lamp light (Spectral power distribution), the color of the light the lamp produces 163 DGMS Annual Report, 2009 (Color temperature measured in Kelvin), the way the light source makes the color appear to human eyes and how well subtle variations in color shades are revealed (Color rendering - Color Rendering Index from 0-100). The higher the CRI is, the better the color rendition appears. An inappropriate color rendition can deceive the eye and supply it with wrong information. Lamp examples :Metal Halide Lamps are High Intensity Discharge Lamps (HID) and have high efficiency and good color rendition. These lamps are used in stadiums, warehouses and industrial settings. High Pressure Sodium Lamps (HPS) are the most efficient of the HID family. Their color rendition, however, is not as good as the rendition of Metal Halide Lamps. HPS lamps are often used for street illumination. Fixture efficiency is affected by two factors. The first factor is the amount of power (watts W) required for the fixture to work at any given time and the amount of light leaving the fixture (Electrical Efficiency). The second is how much light will be produced by the fixture and how much of it will be task efficient (Fixture Efficiency). An inefficient fixture can use the same amount of energy as an efficient one while producing less light. 5.0 Other Criteria Affecting Standards Illumination Activity level in the area can change the requirement of light quantity and quality depending on the function that takes place. Visual acuity is the ability to detect a different aspect of detail. Areas that require high detail differentiation may require high visual acuity. Excessive brightness or insufficient light can hinder visual acuity. High Light Levels and vision. At high light levels absolute sensitivity decreases, contrast threshold increases, the eyes switch to photonic (cone vision) vision. Object recognition depends on the ability of the eye to discriminate differences in illumination within the object and against its environment, not on how bright the scene is. 6.0 Effects of Lighting on Human Health and Psychology. Medical research on the effect of excessive light on the human body suggests that a variety of adverse health effects may be caused by light pollution or excessive light exposure, and some lighting design textbooks use human health as an explicit criterion for proper lighting. Health effects of over-illumination or improper spectral composition of light may include: increased headache incidence, worker fatigue, 164 headaches and increased incidence of carcinoma. light levels can be quantified by field measurement or mathematical modeling. The lamps should be operated from sources of supply which will insure continuity of service and steadiness of light. update and maintain Lighting Plan :(i) (ii) Indicating the location of the places.

Various composition were tried by adding quick setting chemicals and other re-agents in the cement composition.25 to 1. It is highly desired that the roof bolts once installed should immediately start taking load of the roof strata and prevent dilation so as to eliminate chances of roof fall. within the Freshly Exposed Roof Area. The roof Bolts which were 217 .2m. The accidents data analyzed for the past fifteen to twenty years during which the full column grouted roof bolts along with cement capsules were being used. cement grouted roof bolts have almost replaced the timber supports in coal mines in India. Cement is equally important material to be used along with the steel in industries and infrastructure fields. installation. 3 and 6 of 1993 are highly elaborative and exclusive on the subject. 2009 as substitute and is invariably used in the industry including domestic uses. the results are not upto the expected level. 57 to 60% of the total below ground accidents are caused due to fall of roof and sides. In spite of the best effort put in both from the mine operators as well as from this Directorate. Roof Bolts are now being used as common support in underground mines all over the world along with the cement or resin grout to reinforce the strata and provide adequate support in the excavation. resin capsule is now being invariably used and are now economically viable in case of mass production. the use of cement capsules would continue for medium and small scale productions.e. However. Since past ten to fifteen years. Technical Circular No.0 NECESSITY It would be pertinent to mention here the trends of fatal accidents in coal mines especially due to fall of roof and sides. A number of accidents due to fall of roof have occurred within 2 to 4 hours of exposure of the roof where cement grouted roof bolts were used that failed and fell along with the failing roof of thickness varying from 0. have revealed that :(i) (ii) (iii) 38 to 40% of the fatal in coal mines are caused due to fall of roof and sides.4 Tonnes. A number of technical circulars have been issued from this Directorate regarding load requirements.
