Drilling and Blasting Technical Aspects of Mining

Drilling And Blasting Technical Aspects Of Mining

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.
