EMULSION EXPLOSIVE COMPOSITION AND THE METHOD OF ITS PRODUCTION Russian patent published in 2006 - IPC C06B31/28 C06B45/08 C06B47/14 

FIELD: mining; methods of production of the emulsion explosive compositions.

SUBSTANCE: the invention is pertaining to the field of development of the explosive compositions applied at the blasting operations in mining, including in the rocks and the ores containing sulfides. The offered emulsion explosive composition contains a dispersion of the water solution of ammonium nitrate and carbamidum or urotropine in the medium composed of the mixture of a hydrocarbon combustible, an emulsifying composition and a sensitizer. As the emulsifying composition it contains the compounds selected from among amino derivatives of the polyisobutylenesuccinic anhydrides, as the hydrocarbon fuel - the industrial oil or its mixture with petrolatum ointment in the ratio of 0.1ч 1.0, and as the sensitizer - the solid porous particles or the water solution of sodium nitrite, or its mixture with the solution of formaldehyde. The invention also offers the method of production of the given emulsion explosive composition. The invention allows to create the emulsion explosive composition with the high physical stability at a prolonged storage, including the storage at the subzero temperatures.

EFFECT: the invention allows to create the emulsion explosive composition with the high physical stability at a prolonged storage, including the storage at the subzero temperatures.
