Water-Filled Explosives


explosive mixtures containing a certain amount (usually 5-20 percent) of water, along with an oxidizing agent (ammonium, sodium, and potassium nitrates, sodium perchlorate, and others), combustible and explosive substances (aluminum, trinitro-toluene, hexogen, tetranitropentaerythritol), and other additives. The addition of water, by decreasing the possibility of water-filled explosives accidently heating up, cuts their sensitivity to external effects and lessens the danger of handling them. It also gives the substance plasticity and fluidity, thus facilitating the mechanization of the process of charging and filling the entire volume of fuses or blastholes with explosive material. Water-filled explosives are stored and transported in polyethylene containers to prevent their drying out. If large quantities are used, it is more feasible to prepare the water-filled explosives at the place of use (using mixers similar to concrete mixers or using portable mixing-charging sets).

Water-filled explosives are used in industry as secondary (brisant) explosives in blasting operations (in open operations and in mines where there is no danger of gas or dust).
