Drilling And Blasting Technical Aspects Of Mining

1. Drilling and blasting. By far the bulk of rock excavated in mining globally is broken by drilling and blasting. Mining is the largest consumer of civil explosives. Mining explosives are substances which detonate to produce a high-intensity shock wave and large volumes of gas which, being confined in a hole, expand rapidly, entering existing minor cracks in the rock, and creating new cracks to break the

What Are The Techniques And Hazards In Drilling And Blasting

Apr 13, 2021 Blast hole drilling is a technique used in mining whereby a hole is drilled into the surface of the rock, for the purposes of packing it with explosives and detonation. The intention is to induce cracks in the inner geology of the surrounding rock, in order to facilitate further drilling and associated mining
