In mines, quarries, and blast sites there are sometimes areas where the drilled blast holes tend to collapse. In many cases these holes cannot be used for blasting, which causes serious issues like leaving too big blast stones which needs to be redrilled and blasted again. Using of casings in these most problematic areas would solve the issue.
Once the area is surveyed and mining engineers develop plans for the underground mine, construction will begin. The shaft, a vertical tunnel used to move from the surface to different levels of the mine, is created.. By drilling holes and inserting explosives inside, miners blast openings into the rock.

In-The-Hole longhole drill rigs are mounted on tracked or articulated carriers in order to be transported into a mine where it uses extension rods to drill holes and extract ore with the aid of an ITH hammer similar to that of the top hammer drill rig. Additionally, the ITH longhole drill rig also flushes out debris with pressurized water.
Unlike the Mines, there is no elevator to save progress, but on every floor there is a ladder at the starting point where the Player can leave the Skull Cavern. Each visit must start again from the first floor. When ladders to the next floor appear from breaking rocks, 20% of the time they will appear as a shaft (or hole) instead of a ladder.
