| description | FIELD: explosive charges for blasting operations at open and underground mining works. ^ SUBSTANCE: the explosive charge (modification 1) is made in the form of an embanked layer of explosive mixture with a height (Hl) of not less than the critical thickness of the layer of the explosive mixture on a solid surface and an area of contact of the explosive mixture with the crushing surface not exceeding 4Hl 2. The primary initiation agent is positioned in the centre of the embanked layer of the explosive mixture. The explosive mixture contains ground ammonium nitrate with the size of particles not exceeding 1.0 mm and the content of particles with a size up to 0.25 mm at least 20 mass percent, liquid fuel or a mixture of liquid fuel and powdered organic and/or metallic, and/or explosive fuel. The explosive charge (modification 2) includes an explosive and a blast initiator consisting of an intermediate detonator made in the form of an explosive mixture and a primary initiation agent installed inside it. The explosive charge (modification 3) includes an explosive and a blast initiation agent an intermediate detonator in the form of cartridge of an explosive mixture. ^ EFFECT: enhanced efficiency of blasting operations by the explosive charge. ^ 25 cl, 5 dwg, 1 tbl, 3 ex |
