METHOD FOR MINING INCLINED ORE BODIES Russian patent published in 2017 - IPC E21C41/22 

FIELD: mining.

SUBSTANCE: proposed method for mining inclined ore bodies in upward order comprises filling mined space with rock blocks, ore discharge area through trench bottom-cut in confined isolated space. A distinctive feature of method lies in mining of next panel in confined space limited by rock blocks cut in hanging block. The cutting the rock block from the hanging side above the mined panel is carried out simultaneously with blasting of ore in the panel, landing of this block is carried out by means discharge area for blasted panel ore through the trench bottom-cut, at that the inclination angle of rock block sliding plane varies within the limits from the vertical angle the angle of natural slope of blasted ore.

EFFECT: possibility of application the method for mining inclined ore bodies with inclination angle 20-45 degrees and providing complete extraction of blasted ore without dilution in confined space, previously isolated by placed rock blocks, with discharge of ore to the trench bottom-cut.
