FIELD: explosives. ^ SUBSTANCE: invention relates to industrial explosive compositions employed when performing blasting operation on the earth surface of open-pit mines and open-cast mines at temperatures from -50°C to +50°C. In the first embodiment of invention, industrial explosive composition comprises hexogen with particle size less than 0.7 mm, liquid petroleum product with kinematic viscosity below 2400 mm2/s as measured at 20°C and/or coal powder, and dense granulated ammonium nitrate and/or porous granulated ammonium nitrate. Moisture content of composition is below 1.8% (in excess of 100%). Another embodiment provides composition comprising hexogen with particle size less than 0.7 mm, trotyl and/or dinitronaphthelene, liquid petroleum product and dense granulated ammonium nitrate and/or porous granulated ammonium nitrate, moisture content being 1.8% (in excess of 100%). ^ EFFECT: enabled preparation of high-efficiency explosives for use in blasting operations on middle- and high-strength minerals when charging dry and dried wells as well as when placing explosives into polyethylene hoses and cartridges in wells with any degree of watering. ^ 12 cl, 1 tbl |
