METHOD FOR EXTRACTION OF BY-SLOPE MINERALS Russian patent published in 1996 - IPC

Abstract RU 2054120 C1

FIELD: mining industry. SUBSTANCE: minerals blasted in flank are worked up to boundary determined by analytic dependence, and remaining part of blasted minerals is filled up with barren rocks to restore berms, and extraction operations are repeated on open pit districts. Analytic dependence of determination of boundary of worked blasted minerals is offered.
