Abstract RU 2133008 C1

FIELD: mining industry, charging of flooded holes going down with water-carrying explosives. SUBSTANCE: process of charging of flooded holes going down includes installation of hoses for supply of components of water-carrying explosives at different levels of depth of hole and separate supply of solid and liquid components of water-carrying explosive. Solid component of water-carrying explosive is supplied into central part of hole and liquid component is fed to periphery. Hoses for supply of liquid component are positioned in hole at level below level of installation of hose for supply of solid component by 0.5-1.0 diameter of hole. EFFECT: increased efficiency of charging of holes thanks to uniform distribution of components of water-carrying explosive over entire length of string of charge in hole and over area of hole. 2 dwg
