COMPOSITION OF EMULSION EXPLOSIVE SUBSTANCE AND METHOD OF PRODUCING THIS COMPOSITION Russian patent published in 2017 - IPC C06B31/28 

FIELD: chemistry.

SUBSTANCE: in the composition of the substance as porous granules of ammonium nitrate, ammonium nitrate is used in this mixture. Porous granules of ammonium nitrate, in its dry state, are impregnated or moistened with fuel or a fuel mixture of composition that repeats the composition of fuel or the fuel mixture in the water-emulsion matrix in an amount of 5.5-7.5 wt % with respect to the mass of porous granules of ammonium nitrate introduced into the composition of the emulsion explosive. In the composition of the emulsion explosive as nonporous granules of ammonium nitrate, ammonium nitrate can also be used in this mixture, the non-porous granules of which, in its dry state, are moistened with fuel or a fuel mixture of composition that repeats the composition of fuel or the fuel mixture in the water-emulsion matrix in the amount of 1.5 -3.5 wt % with respect to the weight of the granules of ammonium nitrate introduced into the composition of the emulsion explosive. The method of producing an emulsion explosive consists in mixing an aqueous emulsion matrix consisting of fuel or a fuel mixture and an oxidant solution with porous granules of ammonium nitrate. Ammonium nitrate is used as porous granules of ammonium nitrate in this mixture. Porous granules of ammonium nitrate, in its dry state, are impregnated or moistened with fuel or a fuel mixture of composition that repeats the composition of fuel or the fuel mixture in the water-matrix. For impregnation or moistening of porous granules of ammonium nitrate, fuel or a fuel mixture in an amount of 5.5-7.5 wt % with respect to the mass of porous granules of ammonium nitrate introduced into the composition of the emulsion explosive is consumed. The mixing of the water-emulsion matrix is carried out with the impregnated or moistened fuel or the fuel mixture with porous granules of ammonium nitrate.

EFFECT: increased warranty period of storage, high detonation characteristics of emulsion explosives due to chemical homogeneity of the mixture composition.
