    Introduction

    Ring design is the term given to drilling a fan of holes from an underground drive for the purposes of blasting ore. Although there are numerous requirements for each design, Surpac can assist you to create

    and report practically any type of underground ring design.

    RequirementsPrior to proceeding with this tutorial, you will need:

    Surpac 6.0 installed. The data set 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 the process of creating, editing, saving,reporting and plotting underground ring designs.

    Ring Design Concepts

    Overview

    This section will cover some terms used in this manual, some basic concepts of ring design and the filesyou will use during ring design.

    Requirements

    Prior to performing the exercises in this tutorial, some experience in ring design is helpful but is notrequired.

    Terminology

    Centreline a single string segment used in the function Centre line sli ce to create slices from

    solid models. Real World Coordinates a concept where the information in a string file is stored with the

    coordinates representing a plan view of the data. In other words, the coordinates represent the

    mine grid northing, easting, and elevation. Slices of solid objects to be used for ring design must

    be saved in real world coordinates. Section Coordinates a concept where the information in a string file does not represent a plan

    view. Data created using the ring design function Save for plot are saved in section coordinates. Underground Drive a tunnel, or opening in rock where the drill rig will be positioned. Stope a 3-dimensional area (usually ore) which is to be mined out by blasting a series of long

    holes or ring design holes.

    Ring Design Concepts and Files

    In the most common cases, you will need three things to perform ring design:

    3D solid models of surveyed underground drives 3D solid models of designed stopes A string segment to be used as a centreline for slicing solid objects

    For stopeless design, such as for cable bolt holes and "sludge" (or sample) holes, you will need only a 3Dmodel of the drives and the centreline string. If you have a Surpac block model, you may also slice it atthe same time you slice the 3D solid models of drives and stopes. You may also append DTMsrepresenting other features, such as fault surfaces to the drives and stope designs prior to slicing. Afterslicing, and prior to enabling ring design, you may append any other string files (in real world coordinates)to the string files created from slicing.

    The purpose of this tutorial is to expose you to one way of using most of the tools within Surpac to createa ring design.

    Creating a Centreline

    Overview

    The function Centre line sli ce will be used to create slices through one or more solids. A centrelinestring is required to slice the solids. In this chapter you will prepare a string file to act as a centreline,maintaining a pivot point a given distance above the surveyed floor.

    Task: Setting the Profile and Viewing the Data1. Right-click in the empty space at the top of the Surpac interface.2. Select Profiles , and then ringdesign as shown.

    The top of the Surpac window appears similar to the following image.

    The interface now contains a new set of menus and toolbars that cover the functionality for processingdata from a ring design.

    3. Open cl1.str . 4. Open floor1055.str .5. Choose Display > Point > Markers to display markers.6. Enter the information as shown, and then click Apply .

    You will now look at the data in section view, which is defined in Surpac as looking north at the XZ plane.

    7. Click the icon.

    The floor and centreline strings are displayed as shown.

    You will create a set of sections perpendicular to the centreline through several solids. The origin (0N,0E) of each section is set at the pivot point of the drill rig, at a height of 2 meters above the floor. To dothis you will need a centreline for slicing which is 2 meters above the floor for the entire length of thecentreline.

    Slicing Objects

    Overview

    The function centre line slice will be used to create sections of a DTM file comprised of several three-dimensional solid objects. The function uses the centreline created during the previous exercise.

    Task: Viewing the Data

    1. Click the Reset graphics icon .2. Open ringex1.dtm .3. Spin the data around to get a feel for the solids models.

    4. Choose Display > Hide everything .5. Choose Display > Surface or Solid .6. Enter the information as shown, and then click Apply .

    Object 3 represents the ore zone. Notice that it contains holes where the drives pass through it.

    Now you will display objects 1 and 2 individually.

    7. Choose Display > Hide everything .8. Choose Display > Surface or Solid .

    9. Enter the information as shown, and then click Apply .

    10. Choose Display > Hide everything .11. Choose Display > Surface or Solid .12. Enter the information as shown, and then click Apply .

    Objects 1 and 2 are the drives, created from survey data. Object 3 was created by outersecting the solidof the ore zone by the solid of the drives.

    Objects 1 and 2 Object 3 (outersected by objects 1 and 2)

    It is generally a good idea to use outersected solids for creating ring design slices, since the toe (or end)of the hole will be located at the point where the hole intersects the stope. As shown below, if the 3D solid

    of the stope were not outersected by the drives, you may not achieve the desired result.

    Setup

    Overview

    There are several default rig and drilling parameters that are used each time you use ring design. Theseare stored in the text file SSI_ETC:rings.ssi .

    Task: Performing Rig Setup

    You will first set up parameters for a new drilling rig.

    1. Click the Reset graphics icon .2. Choose Ring design > Start ring design .3. Enter the information as shown, and then click Apply .

    Note: The default value of ssi_etc:rings.ssi would read values from a file in the ssi_etc: directory. Inthis example, you will store the data in a file named rings.ssi in the local data directory.

    At the bottom of the Surpac frame, the name of the default rig will be displayed. If you are using ringdesign for the first time, it will display OLD DEFAULT RIG:

    Rather than compiling and continuously updating a database containing all the specifications on thenumerous manufacturers and models of drill rigs, Surpac asks you to define the mast of your drill rig. Youare prompted to enter the shape, size, movement limits and angle definition method of the mast.

    4. Choose Setup > New r ig .

    4. Choose Setup > Rig posit ion .5. Click near the lower drive, then near the stope.

    The rig is positioned in the lower drive as shown.

    When you are selecting a drive to drill from, it is not necessary to click precisely on the drive segment, butonly near the segment. Also, when you are selecting a drive, only those strings which you havenominated as survey opening strings above are selectable. The string numbers which you havenominated as stope outlines are not selectable.

    When you are selecting a stope string, the survey opening strings are not selectable. In this case, whenyou select the new rig position, you could double-click anywhere near the lower drive. The first click willselect the drive, and the second click will select the stope.

    The tolerance is used with the function Create holes - Between two holes . When fitting holes with thisfunction, you are asked to select two holes that have been drilled from the same pivot point, with theassumption that additional holes will fit between the two selected holes.

    When Surpac attempts to fit additional holes with a given toe spacing, invariably the last hole to be fitted

    will be too close to the second hole chosen. The tolerance value is used to allow the toe spacing of holesfitted between the two holes to change by up to this amount. Surpac iterates a given number of times,varying the toe spacing up to the specified tolerance, until an acceptable toe spacing is found to allow thenew holes to fit between two holes.

    The minimum collar distance does not allow holes to be drilled where the distance between the centresof the holes is less than this distance.

    Overdrill allows you to create holes that are drilled past or short of the stope outline. For example, if youset overdrill to 0.5, the holes would be drilled 0.5 units (meters or feet) past the stope outline. If you setoverdrill to 1, the holes would stop 1 unit of measure (ie. 1 meter or 1 foot) before the hole wouldintersect the stope outline.

    Note: Nearly all functions and concepts in Surpac are unitless that is, it does not matter if you are using units of feet or units of meters.

    The hole diameter is the diameter of the hole in units of measure (0.05 meters in this example). Thediameter can be used for reporting and for blast powder factor calculations.

    The direction of the ring is used when drilling normal holes. For example, if the direction of the ring isset to clockwise, and you create two normal holes from a vertical hole, they will be rotated clockwise fromthe vertical hole.

    The view-only hole colour is assigned to holes drilled from other rings. It is sometimes convenient toview the holes from a previous ring so that holes in the current ring can be staggered.

    The break-through tolerance is used to control the length of holes which have the potential to be drilledinto surveyed drives. If the hole is to be drilled to the edge of a surveyed drive, set the break-throughtolerance to a very small number, such as 0.001. If set to zero, holes will pierce through drives. In ourcase, we want holes to be stopped 0.75 meters before they break through a drive.

    For more information on the fields, click the Help button to display the online reference manual, and/orreview the field and form help.

    8. Choose Ring design > Save ring design settings .9. Enter the information as shown below, and then click Apply .

    In practice, you would normally use the default file of ssi_etc:rings.ssi . You are saving rings.ssi in the local directory for training purposes only. You have now completed setting up a drill rig andits drilling parameters, as well as storing the information in the ring design defaults file.

    Moving the Mast

    Overview

    The drill mast may be moved and rotated inside a surveyed opening to position it for drilling holes. Oftenthe distance left or right of a single pivot point of the rig or the distance of collar positions from acentreline are required in a report. To do this, we need to open the centreline file in a new layer and letSurpac know that we want all holes drilled to be reported relative to this centreline.

    Task: Using a Centreline String as a Reference Line1. Open cl1.str .

    2. From the Ring Design menu bar choose View > Zoom to extent of current section .3. Zoom in on the drive where the rig is positioned.

    4. Choose Move mast > By graphics .5. Practice moving the mast by clicking and dragging it around.6. Press ESC to terminate the function.

    If you attempt to position the mast so that the pivot point is outside the dotted line, or any part of the mast is outside the drive, you will get an error message, and the mast will be moved back to itsoriginal position. Although you can move the mast around, none of the holes drilled from these newpositions will be referenced to the centreline until we explicitly select the centreline.

    7. Choose Setup > Select reference line for offsets . 8. Click the centreline string.

    9. Click and drag the mouse on the screen to view the data as shown:

    Task: Moving and Rotating the Mast

    You will now examine several functions that allow you to move and rotate the mast. These functions arepresented to demonstrate various options and are not in a specific order.

    1. Choose Move mast > By coordinates . 2. Enter the information as shown, and then click Apply .

    The mast is moved so that its pivot point is on the centreline. By selecting a reference line, we have setup a coordinate system within the plane of the section whose origin is at the point where the centreline

    pierces the section. This coordinate system is only used for positioning the rig, and for reporting the rigpivot point position relative to the centreline.

    3. Choose Rotate mast > To angle .4. Enter the information as shown, and then click Apply .

    The mast is rotated to an angle of 300 degrees as shown.

    The value "angle" in the function Rotate mast - to angle is a value from 0 to 360, with the origin beingvertically up the section.

    5. Choose Rotate mast > By angle .

    Creating and Reporting Holes

    Overview

    Holes may be created, moved and rotated inside a stope, or without a stope. In this chapter, you willcreate and edit holes inside a stope.

    Task: Creating and Editing Holes

    In the last chapter, the rig named tutorial was positioned in the lower drive of section 9, from the file1055sec9.str , 0.6m from the right wall, as shown below:

    1. Choose Create holes > At current mast orientation .

    This will create one hole at the current mast orientation. Notice that the toe or end of the hole ispositioned exactly at the stope outline. In the Define Rig Parameters form, you specified anoverdrill distance of zero. Had you specified an overdrill of 0.5, the hole you just created wouldextend 0.5 meters past the stope outline. An overdrill of 0.25 would have stopped the hole 0.25meters short of the stope outline.

    2. From the Ring Design Menu choose View > Hole IDs four times (until you see the number "1" forthe second time).

    This option toggles the hole id as a number, a letter, or no id.

    4. Click hole number 1.5. Enter the information as shown, and then click Apply .

    Two holes are drilled parallel to hole number 1.

    Note: A negative horizontal spacing indicates that the holes are drilled to the left of the selectedhole. A positive spacing would mean that holes are created to the right of the selected hole.

    You will now see three holes, as shown.

    Assume that after looking at this result, we decide that we would rather drill hole number 3 and allremaining holes with the rig at the centreline point. We will first delete hole number 3 and then re-create itwith the pivot at the centreline and a toe spacing of 1.5 meters from hole number 2.

    6. From the Ring design menu choose Edit > Delete one hole 7. Click hole number 3.

    Hole number 3 is removed.

    Next, you will move the mast back to the pivot point.

    Hole number 3 will be created to the left of hole number 2, using the AECI algorithm, and a toe spacingdistance of 1.5.

    Note: See the online help for more information on toe spacing algorithms

    Next, you will drill another hole along the footwall contact, and then a fan of holes between these last twoholes.

    15. Choose Create holes > At selected location .16. Click a location on the left stope wall to create a hole similar to that shown.

    You will now rotate this hole to the lower stope limit, or footwall.

    17. From the Ring design menu choose Edit > Rotate hole .18. Click hole number 4, then release to select hole number 4.19. Click hole number 4 again and drag it to the lower stope limit, or footwall as shown.

    It is not necessary that the holes fall entirely within the stope design. The decision to drill this hole slightlyoutside of the stope is purely a judgement call. In this case the hole extends beyond the stope, and youwill now adjust the length of the hole.

    20. From the Ring design menu choose Edit > Edit hole length graphically .21. At the prompt, click and drag the toe, or end of the hole to the new position.

    When you release the mouse, the length of the hole will be reset to that position. This function isnot an exact means of setting a hole length.

    Following is an exact method of setting a hole length.

    22. From the Ring design menu choose Edit > Set length of one hole ,23. Click hole number 4.24. Enter the information as shown, and then click Apply .

    25. Press ESC to terminate the function.

    You will now drill a fan of holes between holes 3 and 4.

    26. Choose Create holes > Between tw o holes .27. Click hole 3, and then hole 4.

    Remember that you previously set the direction of the holes to be created as anti-clockwise . As a result,you must select hole 3 first, and then hole 4. If we selected hole 4 first and then hole 3, Surpac wouldattempt to create holes anti-clockwise from hole 4 to hole 3.

    As described previously in Setup , the value entered for tolerance on the Drilling Parameters form isused with the function Create holes .

    When fitting holes with this function, you are asked to select two holes which have been drilled from thesame pivot point, with the assumption that additional holes will fit between the two selected holes. WhenSurpac attempts to fit additional holes with a given toe spacing, invariably the last hole to be fitted will betoo close to the second hole chosen.

    The tolerance is used to allow the toe spacing of holes fitted between the two holes to move by up to thisamount. Surpac iterates a given number of times, with slightly varying toe spacings, given that the toespacing does not vary by more than the tolerance given here, until an acceptable toe spacing is found.

    When the tolerance is used to fit holes between two holes, it attempts to keep the toe spacing as close as

    possible to the original. To do this, it must make several attempts with different toe spacing distances.

    The number of attempts or iterations it makes to fit the holes is set on the next form. For most cases, 5iterations are acceptable. The greater the number of iterations, the longer it may take to fit holes betweenthe two selected holes.

    28. Enter the information as shown, and then click Apply .

    The holes will be created between holes 3 and 4. Notice that several holes which came near, or wouldhave intersected the upper drive, were shortened. When holes would normally terminate at a surveyedopening, they are shortened by the break-through tolerance value. In our case, this was set to 0.75m onthe Drilling Parameters form.

    The hole numbers reflect the order in which they were created. However, we assume that all holes needto be numbered in a clockwise manner, starting on the footwall.

    29. From the Ring design menu choose Edit > Renumber holes .30. Enter the information as shown, and then click Apply .

    31. Click hole number 4.

    The holes are renumbered clockwise from 1 upwards, starting at the footwall.

    Task: Saving Holes

    You have now completed the ring design, and will save the holes.

    If you were attached to a ring design database, the holes would be stored in the database. However, forthis example you will store the holes in a string file.

    Task: Saving Default Values

    You have now set several values which need to be stored in the ring design defaults file. Beforecontinuing further, you will save these default values.

    1. Choose Ring design > Save ring design settings .2. Enter the information as shown, and then click Apply .

    Note: In practice, you would normally want to use the default file of ssi_etc:rings.ssi . You are savingrings.ssi in the local directory for training purposes only.

    It is strongly recommended that you do NOT modify this file with a text editor, as a simple modification tothe format of the file could result in the loss of default parameter data.
