METHOD OF FORMATION OF CONTOUR HOSE CHARGES FROM WATER-CONTAINING EXPLOSIVES Russian patent published in 1997 - IPC

FIELD: mining industry, applicable in opencast mining of mineral resources for sloping of high walls in open casts and in water-development projects. SUBSTANCE: the method consists in mixing of thickened aqueous solution of oxidant with solid sensitizer - granulotrinitrotoluene and cross-linking agent with variation of percentage of granulotrinitrotoluene at a solution temperature below the melting point of granules of granulotrinitrotoluene, filling of polyethylene hose with a diameter corresponding to the charge mass per meter of the borehole, placed in the borehole or formed on the surface of the high wall with subsequent placement of it in a contour borehole. EFFECT: facilitated procedure. 1 dwg, 1 tbl
