Although there are numerous requirements for each design, Surpac can assist you to create practically any type of mine design. Requirements Prior to proceeding with this tutorial, you will need: • • • Surpac 6.0 installed The dataset accompanying this tutorial A basic knowledge of Surpac string files and editing tools as covered in the Introduction to Surpac manual. Objectives The objective of this tutorial is to allow you to understand some of the string editing tools available in Surpac to create a decline and production access points into stopes. Page 4 of 47 In this tutorial the workflow is as follows: Page 5 of 47 . from the bottom and design up. or start in the middle of the deposit and proceed up and down at the same time. The workflow you adopt will generally be the one which you find best for you.Introduction Workflow Workflow The process of performing underground mine design described in this tutorial is only one of many different approaches. There is no single set of steps which is generally employed in the process. You may want to start from the top and go down. you will use: • • • 3D solid models of designed stopes.Underground Design Concepts Workflow Underground Design Concepts Overview To create an underground mine design using Surpac requires an understanding of underground mining terminology and concepts. a point representing the location on the surface which is an entrance to the underground mine. also known as a drift. You will open files containing this data into graphics. or crosscut Stope – a 3-dimensional area (usually ore) which is to be mined out by blasting a series of long holes or ring design holes Underground Mine Design Concepts in Surpac There are many different scenarios where underground mine designs are to be created. Terminology • • • Centreline – a line which represents the centre of a drive. Drive – a tunnel. but not required. In this tutorial. Page 6 of 47 . some experience in underground mine design is helpful. This section will cover some terms used in this tutorial and some basic concepts of underground mine design. or outlines for plan view plots. The centreline can be used to create solid models. Requirements Prior to performing the exercises. or opening in rock. and then use various editing and point creation tools to create the underground mine design. strings representing ore outlines at each level where a design is to be created. 2. In the Surpac Navigator. select Set as work directory. Page 7 of 47 . Files used in this tutorial are stored in the folder: <installation directory>\demo_data\tutorials\underground_mine_design where <installation directory> is the directory in which Surpac was installed. right-click the underground_mine_design folder. The name of the work directory is displayed in the title bar of the Surpac window.Setting the Work Directory Task: Setting the Work Directory Setting the Work Directory A work directory is the default directory for saving Surpac files. Task: Setting the Work Directory 1. From the popup menu. as covered in the Introduction to Surpac manual. The creation of a centreline can be performed by many different functions within Surpac. It consists of a series of three-dimensional solid objects representing an underground mine design. Page 8 of 47 . 4. Open ugdes_final1.dtm in this tutorial. Requirements Prior to performing the exercises in this chapter.Creating a Centreline Design Task: Viewing the Data Creating a Centreline Design Overview An underground design begins with the centreline.dtm. Task: Viewing the Data 3. This file represents two parallel ore zones.dtm You will be creating a part of the file ugdes_final1. Open stopes1. you should have: • a basic knowledge of Surpac string files and editing tools. but is basically the creation of three-dimensional points in space. 8. Enter the information as shown.

The start point of string 1 is the point at which the production crew will begin mining to implement the design. 6. you will begin the design at the ore zone. and work back to this point. and click several different segments. 9. Click the Reset graphics icon Open lev215. Choose Display > Strings > With string numbers to display all strings with numbers. Open stopes1. In this case. You will now create a design starting from the 200 level up to lev215. Note: The main graphics layer currently does not contain any data.str. you do not have to begin the design at this point. Spin the data around to get an idea of how the strings are formed in 3D space. Choose Display > Hide everything. the Z value of the new points will also be 200.Creating a Centreline Design Task: Creating a Centreline Between Ore Zones As shown in the final design previously. where the Z value of both points is 200. Click two points on the south end of the ore zones to create another point midway between the two selected points. The Z value of the created points will be equal to the average of the Z values of the two selected points. Choose Create > Digitise > New midpoint. 11. the string used to create the main drive between the two ore zones is string 10. Click two points on the north end of the ore zones to create a point midway between the two selected points. 12. and then click Apply. as shown: 15. Enter the information as shown. 14.

Creating a Centreline Design Task: Creating the Main Decline Task: Creating the Main Decline Overview You will now create the decline from the access point on the 215 level to the southern end of the main drive between the two ore zones. Here are the constraints to be used in this design: • • • • • The gradient from the Access Point to the Start of the Decline will be flat. The curve numbers given here will be referred to throughout the remainder of this section of the tutorial. There must be a 5 meter straight section between curves 2 and 3. as illustrated below. Page 21 of 47 . The gradient from the Start of the Decline to the End of the Decline can be no more than 15% Curve 1 will have a radius of 20 meters. Curves 2 and 3 will have a radius of 30 meters.

Enter the information as shown.Creating a Centreline Design Task: Creating the Main Decline 50. So the southern end of curve 2 is now at the same elevation as the Access Point. the bearing of a line perpendicular to the centreline of the Access Point (as well as being tangent to the last point on curve 2) will be 90 degrees less than that.
