Drilling and Blasting Technical Aspects of Mining

Drilling. 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
