METHOD OF MANUFACTURE OF THE BLASTING EXPLOSIVE AND THE BLASTING EXPLOSIVE PRODUCED BY THIS METHOD Russian patent published in 2007 - IPC C06B31/38 C06B21/00 

FIELD: chemical industry; mining industry; building industry; methods of production of the mixed blasting explosives.

SUBSTANCE: the group of the inventions is pertaining to manufacture of the mixed blasting explosives used for the molding of the charges arranged in the explosion cavities in mining and building. The group of the inventions presents the method of manufacture of the blasting explosive and the blasting explosive manufactured by this method. The method of manufacture of the blasting explosive includes the heating of the granulated ammonium nitrate up to the temperature by 5-10°С higher than the melting temperature of dinitrotoluene (DNT), introduction at stirring action in the ammonium nitrate of the solid DNT in the crystalline form with the dimension of the agglomerate of no more than 5 mm in amount of 10-20 mass %, stirring action till completion of the DNT adsorption process in the ammonium nitrate, cooling of the produced mixture to the temperature of no more than 50°С. The invention has the purpose to improve the explosive and operational characteristics of the loose nixed blasting explosive on the basis of the ammonium nitrate and dinitrotoluene.

EFFECT: the invention ensures production of the loose mixed blasting explosives on the basis of the ammonium nitrate and dinitrotoluene with the improved explosive and operational characteristics.
