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.

Initial effects of improved drill and blast practices on

there were no drill and blast engineers to keep track of the drilling, timing, and blasting process. An external contractor would supply the explosives and advise the charging and blasting practice to mining personnel. The drill designs were completed by mine planning engineers. Changes have been made to the existing longhole process. It now includes drill design, drill and blast QA/QC, survey
