Web5 de mai. de 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 …
Web17 de mar. de 2024 · Rock fragmentation due to blasting depends upon many parameters. The properties of the explosive are one of them. In limestone quarries, ammonium nitrate–fuel oil (ANFO) or site mixed emulsion (SME) are generally used for rock fragmentation.
