METHOD FOR OPENCAST MINING OF INCLINED AND STEEPLY DIPPING MINERAL DEPOSITS Russian patent published in 1995 - IPC

Abstract RU 2027856 C1

FIELD: mining industry. SUBSTANCE: end flanks of opencast are higher and have curvature radius less than that of longitudinal flanks. Parameters of opencast flanks are equalized by filling rocks in opencast deep end. Spacer prism is formed of rocks of block by deepening intermediate bottom from edge of dump rocks in direction opposite to its slope. Offered are relationships of opencast flanks and dependence of resulting incline of final bottom of opencast on affecting factors. EFFECT: higher efficiency. 4 dwg
