FIELD: explosives. SUBSTANCE: invention provides explosive composition for oil-and-gas and mining industries suitable, in particular, for operations under elevated temperatures and pressures in deep wells. Composition consists of perchlorate-type oxidant, nonexplosive organic fuel, metallic fuel, and brisant explosive. Composition is used to prepare charges in the form of blasting cartridges with porosity 0.01-0.15. EFFECT: increased density and heat resistance, and lowered hygroscopicity. 8 cl, 4 ex |
