    Most blasting in mines involves charging explosives into holes drilled in rock. The entrance or mouth of a drill hole is called the collar and the end is the toe. Drilling is still carried out in some cases in the ASM sector by hand using a hammer and chisel. This is obviously tedious and slow especially in hard-rock mining conditions.
