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 ...

Improve mining operations with smart mining - Ericsson

Drilling involves risks to workers, the environment, and the economics of a mine. But it can be made much more accurate and cost-efficient with autonomous drilling rigs, which increase productivity by up to 60%. This process enables continuous drilling after blasting, as there’s no need to remove workers for ventilation purposes.
