In rock drilling, blasting, crushing, and grinding, the effective energy used in rock breakage is found to be quite small in comparison with the total input energy. For example, in rock drilling it is estimated that only 10% of the input energy is used to fracture rock, while most of the input energy is wasted as heat or other forms of energy [12].

The traditional method of drilling and blasting is to treat the two items as separate processes. A driller comes in to drill a hole; a blasting company puts explosives in the hole and blasts it. If you keep these two items separate, you cannot always achieve the best results. It’s not “chemical crushing,” as [Hissem] and I call it.
