FIELD: production of industrial explosives usable for blasting operations in mining practice. SUBSTANCE: explosive composition is prepared by ballistite method and comprises, wt.-%: ammmoniacal saltpeter, 52.0-54.0; gun powder grit, 27.0-29.0; colloxylin, 6.0-7.0; nitroglycerol, 4.1-4.5; dinitrate diethylene glycol, 4.9-5.5; urea, 1.0-1.5; and paraffin, 1.5-2.0. Composition has enhanced resistance to moisture. To produce it, use is made of artillery ballistite-type outdated gunpowders with expired storage life or explosive charges withdrawn from armament, thereby solving problem of their economic and environmental reclamation. EFFECT: higher efficiency. |
