Commercial explosives and blasting agents are composed of low-density heterogeneous mixtures of fuels, oxidizers, and other components, in contrast to high-density military explosives, which are generally mixtures of molecular explosives and binders. The amount of commercial explosives sold each year, which has been estimated by the US Bureau of Mines to be two million metric tons in the USA alone, represents the vast majority of all explosives used each year [1]. Commercial explosives are used primarily for mining, tunnel construction, and other specialized applications, and their use was revolutionized in the mid-1950s with the widespread use of cost-effective ammonium nitrate fuel oil (ANFO) explosives and further in the 1970s with the development of slurry and emulsion explosives [2], which are water-resistant, safe to handle, and in most cases contain no inherently explosive ingredients. Commercial explosives are formulated to be insensitive and are usually oxygen-balanced to minimize the amount of the poisonous gases CO and NOx that is produced during the detonation. They can be mixed on-site and usually require the addition of sensitizers to render them detonable. Current formulations are designed to maximize the work done by the expanding detonation products, in contrast to military explosives, which have higher detonation pressures and a superior ability to accelerate metal. The variation in the formulations of slurry and emulsion explosives is almost limi
