Create holes offset from existing hole with rig movement
The Multiple Holes function operates in a very similar manner to Normal Holes, drilling the specified number of holes at the current toe spacing, in the current direction, starting from an existing hole. Multiple Holes, however, also allows the horizontal movement of the pivot position between holes. A value of 0 (zero) movement between holes causes the function to act in exactly the same manner as Normal Holes.
To run this function: Choose Design > Ring design > Create holes > Offset from existing hole with rig movement, or...
Indicate the first hole. Press (ESC) to quit
Select an existing hole to display the NUMBER OF HOLES form.
Number of holes
Enter the number of holes to be drilled by this function and choose Apply to display the MAST MOVEMENT form.
Amount of rig movement in X
Enter the amount of horizontal movement of the pivot point for each hole. A value of 0 (zero) causes the function to act in the same manner as Normal Holes. A positive value moves the mast to the right, whereas a negative value moves the mast to the left. Choose Apply to generate the specified number of holes with the specified pivot spacing.
After the holes have been drilled, over- or under-drill is added to the new holes and they are checked for break-through (see DRILLING Parameters).
This function requires an existing hole.
The Multiple Holes function requires the selection of a pre-existing hole as a starting position. Use Start to drill this hole prior to using Multiple Holes.
The New Rig position would be located outside the Survey Opening
Warning message indicating that the mast cannot be rotated or moved to one of the new hole positions and remain in the survey opening.
Adding overdrill to new holes
The specified amount of over- or under- drill is being added to the new holes.
Hole X would breakthrough an opening and has been shortened.
The named hole crosses within the specified Break-through Tolerance (see DRILLING Parameters) of an opening.
The collar position of the new hole is too close to an existing hole.
An attempt was made to drill a hole with a collar position that was within the specified Minimum Collar Distance of an existing hole (see DRILLING Parameters). Reduce the minimum collar distance or delete the hole causing the problem.
The specified hole will not intersect the selected stope.
An attempt was made to drill a hole that did not intersect the stope outline.
