Combustion burning is a process by which energy is released.Deflagration and detonation are two ways energy may be released.If the combustion process propagates outward at subsonic speeds slower than the speed of sound, its a deflagration.If the explosion moves outward at supersonic speeds faster than the speed of sound, its a detonation.
Mining - mining - underground mining when any ore body lies a considerable distance below the surface, the amount of waste that has to be removed in order to uncover the ore through surface mining becomes prohibitive, and underground techniques must be considered.Counting against underground mining are the costs, which, for each ton of material mined, are much higher underground than on the.
