Different Types of Explosives Used in Mining The Balance
Apr 21, 2019 Primary explosives can be easily detonated due to their extreme sensitivity to heat, friction, impact, static electricity. Mercury fulminate, lead azide or PETN (or penthrite, or more properly Penta Erythritol Tetra Nitrate) are good examples of primary explosives used in the mining industry.

Dangers of Toxic Fumes from Blasting cdc.gov
blasting agents used in large-scale surface mine blasting do not detonate properly in boreholes of 1-inch 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).

Explosives and Detonators Mining and Blasting
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.
