FIELD: explosives. ^ SUBSTANCE: invention provides blasting composition containing zinc white or powdered zinc oxide as sensitizer and dibasic and/or tribasic gunpowder, or dibasic and/or tribasic propellant. Also, a method for preparing blasting composition is provided comprising comminution of charges of dibasic and/or tribasic gunpowder, or dibasic and/or tribasic propellant at 60-80°C and then stirring of comminuted charges with sensitizer thermomechanically on continuously operated rolling machines operated at roll temperature 50-100°C to form blasting composition in the form of granulated product. ^ EFFECT: increased susceptibility to detonation impulse, reduced value of critical detonation diameter, and weakened susceptibility to mechanical impacts. ^ 4 cl, 10 tbl, 5 ex |
