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 conditions. Hand-drilled holes seldom exceed 400mm in

Selective limestone mining without drilling or blasting

over drilling and blasting is that the limestone can be loaded directly onto trucks by means of a powerful transfer system. Eurocement makes use of further loading methods, however. If, for example, material is required for a temporary embankment stabilization, the surface miners discharge the cut limestone sideways onto a pile. One benefit here is that the cutting pro-cess is always entirely
