Apr 06, 2021 Explosives used in mining are chemical compounds or mixtures that reacts at high speed. This liberates gas and heat resulting in high pressures. High explosives detonate whereas low explosives deflagrate. Both high and low explosives initiation is by a single No. 8 blasting cap. As opposed to blasting agents which cannot be so initiated.

May 05, 2015 explosives 1. Introduction An explosive material, also called explosive, is a reactive substance that contains a great amount of potential energy that can produce an explosion if released suddenly, usually accompanied by the production of light, heat, sound, and pressure. This potential energy stored in an explosive material may be chemical energy , pressurized gas or nuclear energy.
also possible to blast effectively with low-cost, low-detonation pressure explosives, although borehole blasting of cornices increases efficiency, boring holes along the presumed tension line exposes the ava-lanche blaster to considerable danger.
