METHOD FOR WORKING MINERAL DEPOSITS Russian patent published in 1995 - IPC

FIELD: mining engineering. SUBSTANCE: method involves cutting of prepared mineral resources block from the surrounding rock. An inclined flat floor and a receiving working adjacent to it are built in the ground of the block. Supporting benches sloping towards the block are formed in the surrounding rock and above the stope drift in the block. Sloping wells are drilled in the lower part of the block and the dispersing fluid is pumped in. The supporting benches are destroyed layer-by-layer and the dispersed mineral resource body is forced out into the receiving working, where the useful components are selected, dispersing fluid is removed, tails are supplied to fill space over the sinking block and the dispersing fluid is transferred to be recovered and reused. EFFECT: enhanced effectiveness in mining mineral resources containing valuable crystals. 1 dwg
