Create holes parallel to an existing hole
This function allows you to drill the specified number of holes at the specified horizontal spacing parallel to an existing hole.
To run this function: Choose Design > Ring design > Create holes > Parallel to an existing hole, or...
Number
Enter the number of holes to be drilled by this function.
Horizontal spacing
Enter the amount of horizontal movement of the pivot point for each hole. 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 horizontal 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 Parallel Holes function requires the selection of a pre-existing hole as a starting position. Use Start to drill this hole prior to using Parallel Holes.
The New Rig position would be located outside the Survey Opening
Warning message indicating that the mast cannot be 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.
HoleXwould 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.
