METHOD FOR WORKING STEEPLY DIPPING ORE BODIES Russian patent published in 1995 - IPC

Abstract RU 2047769 C1

FIELD: mining engineering. SUBSTANCE: method involves stripping steeply dipping ore body by means of underground working, cutting development and first workings, drilling blast and compensation holes around the outline of the ore body. Wells for pumping in are drilled in the ore mass and dispersing fluid is pumped in. After having saturated the ore mass with dispersing fluid, it is cut off from the surrounding rock and weakened by exploding charges of explosives in the contour blast holes. EFFECT: accelerated method for working mines. 2 dwg
