The technique of rock breakage using explosives involves drilling blastholes by percussion or rotary-percussive means, loading the boreholes with explosives and then detonating the explosive in each hole in sequence according to the blast design. The explosion generates a stress wave and significant gas pressure. Following the local fracturing at the blasthole wall and the spalling of the free A & A Drilling and Blasting Inc.
