With proper understanding of the rocks and blasting methods, the mining work can be done effectively.,Blasting is the processDrilling 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.Enabling Better Blasting - Industrial & Mining Explosives,,process, blasting is widely understood to bear considerable inuence over subsequent stages," suggests Dyno Nobel's Lamont.
