The largest commercial application of explosives is mining.Whether the mine is on the surface or is buried underground, the detonation or deflagration of either a high or low explosive in a confined space can be used to liberate a fairly specific sub-volume of a brittle material in a much larger volume of the same or similar material.
An Analysis and Prevention of Flyrock Accidents in Surface Blasting Operations by T. S. Bajpayee, Harry C. Verakis, and Thomas E. Lobb Abstract Blasting is a primary means of extracting minerals and ores at surface mining operations. The domestic consumption of explosives and blasting agents during the year 2002 was about 5.53 billion pounds.
commercial explosives ranges from 0.6 to 1.7 g/cc. For free running explosives, the density is often specified as the pounds of explosives per foot of charge length in a given size borehole. With few exceptions, denser explosives give higher detonation velocities and pressures. Density is an important consideration when choosing an explosive.
