Blasting | Rock Fragmentation, Drilling & Explosives

blasting, process of reducing a solid body, such as rock, to fragments by using an explosive. Conventional blasting operations include (1) drilling holes, (2) placing a charge and detonator in each hole, (3) detonating the charge, and (4) clearing away the broken material. Upon detonation, the chemical energy in the explosive is liberated, and ...
