blasting agents used in largescale surface mine blasting do not detonate properly in boreholes of 1inch diameter or less (ISEE, 1998). If the blasting agent is diluted by mixing with drill cuttings at the top or bottom of the borehole it may not detonate properly and excessive quantities of toxic fumes may be produced (Sapko, 2002).
commercial explosives can be grouped into two main categories according to their sensitivity, detonator sensitive explosives and blasting agents. Some explosives with very high sensitivity, such as pure nitroglycerin or dynamite, can be detonated by mechanical impact or friction. The sensitivity of an explosive has other operational implications.
