Explosive Selection Criteria
One of the groups of parameters that can be controlled by the technicians in blastings is that of the explosives. The selection of the type of explosive forms an important part of the blast design and, consequently, the obtainable results.
Explosive selection is dictated by economic considerations and field conditions. The blaster should select a product that will give the lowest cost per unit of rock broken, while assuring that fragmentation and displacement of the rock are adequate for the job at hand.
