EXPLOSIVE COMPOSITION GRANOMON FOR BREAKING OF ROCKS Russian patent published in 2019 - IPC C06B31/32 C06B25/08 C06B45/22 

FIELD: chemistry.

SUBSTANCE: invention relates to ammonia-nitrate granulated industrial explosives for manual or mechanized charging of bore pits and wells on open surface and in faces of underground mines during breakage of rocks, including those containing sulphide ores. Explosive composition contains, wt. %: porous ammonium nitrate or its mixture with granular dense ammonium nitrate in ratio 50/50 76.4–97.9, solid fuel - dinitroso compound: dinitrotoluene or dinitronaphthalene, or their mixture with trinitrotoluene in the form of elements with size of up to 10 mm and up to 20 mm respectively 0.8–17.6, liquid fuel - oil product: mineral oil or diesel fuel 1–4, and stabilizer - diphenylamine or carbamide 0.3–2. Composition can also contain fuel oil, dimethyl diphenyl urea, and as a trinitrotoluene, there can be contained flaked TNT or granulotol or TNT.

EFFECT: composition has high detonation capacity, relative operability, density, simpler and less expensive manufacturing process and wide raw material base, which expand its application area.
