METHOD OF PRODUCTION OF THE OXIDATIVE PHASE OF THE EMULSION BLASTING EXPLOSIVES Russian patent published in 2007 - IPC C06B23/00 C06B31/28 C06B47/14 

FIELD: chemical industry; mining industry; methods of production of the oxidative phase of the emulsion blasting explosives.

SUBSTANCE: the invention is pertaining to the blasting explosives applied at the shooting operations in mining, and to the methods of their production. The invention presents the method of production of the oxidative phase of the emulsion blasting explosive, which includes the water solution of calcium and ammonium nitrates, in compliance to which they intermix the ammonium nitrate solution produced at the stage of conversion of the process of manufacture of the granulated ammonia saltpeter and the calcium nitrate solution received at the stage of filtration of the process of manufacture of the nitroammophos in the ratio of 50÷90/10÷50. The invention allows to decrease the power input and the labor input of the process of manufacture of the matrix emulsion of the emulsion blasting explosive and ensures the increase of its quality.

EFFECT: the invention allows reduction of the power input and the labor input of the process of manufacture of the matrix emulsion of the emulsion blasting explosive and ensures the increase of its quality.
