When designing a blast, it is important to know how deep each of the blast holes should be. Vulcan has an option in the ‘Drill and Blast’ tools in the ‘Open Pit’ menu, but what do you do if you don’t have this menu? The referenced script will allow the user to identify the distance from the hole collar to a given elevation and output this value to the point name.
I first came up with the idea for this script when we were having trouble controlling the bench level on each bench. The floor of the pit was becoming increasingly uneven and management’s method of solving the problem was to have the survey crew shoot in each collar, calculate the depth to the next bench (plus sub drill) and mark it on the stake for that hole. I didn’t want my friends on the survey crew to take hours out of their day to write elevations on wooden stakes so I put together this little script. Now they print the blast pattern with hole depth and give it to the driller, leaving them with plenty of time to survey working faces for me .
