Comminution an overview ScienceDirect Topics
Blasting entails drilling holes in mine walls or benches, filling the holes with stone explosive and exploding out fragments of rock. The explosions cause cracks to propagate through the rock, releasing multiple fragments of rock. Burger et al. (2006) reported that closer drill holes and larger explosive charges make smaller rock fragments. This decreases subsequent crushing and grinding
