PROCESS OF LOADING OF DOWNGOING HOLES WITH WATER-CARRYING EXPLOSIVES (VERSIONS) Russian patent published in 2000 - IPC

FIELD: mining industry, loading of holes, in particular. SUBSTANCE: characteristic feature of proposed process is usage of both traditional industrial explosives and of salvageable ammunition not suitable for mechanized loading. In case of usage of grounded salvageable ammunition hose feeding thickened solution of oxidizer is lowered to bottom of hole in advance. Then explosive is poured from hopper machine to certain height through clearance between hose and hole walls. After it thickened oxidizer is fed over hose and hose is lifted to form charge of water-carrying explosive. In case of manual loading portions of grounded salvageable explosive are poured from sacks and portions of thickened oxidizer are fed over loading hose to face of explosive. It is also allowed to pour portion of grounded salvageable ammunition without lifting loading hose. EFFECT: increased technical-and-economic indices of loading process. 13 cl
