RECOVERY METHOD OF MINERALS Russian patent published in 2009 - IPC E21C41/00 

FIELD: mining.

SUBSTANCE: invention relates to mining industry, to methods of combined development of deposits. Recovery method of minerals 20 includes removing of overburdens 15, recovery of minerals 20 and reclaiming which are implemented by one inclined benching mine working, opening access to mineral 20 from surface and translating by measure of extraction of mineral 20 with travel of covering 15 and destroyed mountain mass 3 into releasing after excavation space with formation of dump 3, slope gradient of which is equal to angle of slope of excavation. Translational displacement of stepped incline mine opening is implemented by means of lateral, forming together by vertical line one inclined excavation with introduction of face of each lateral opening under massif of undisturved rock 2. Driving of lateral opening is implemented by devices 1, installed vertically-stepwise one to other and on formed bench 3 of mountain mass, herewith transportation of mountain mass from driving, for its placement into dump 3, is implemented through this row of devices 1.

EFFECT: invention provides cheapen of extraction and increasing of process ecological compatibility.
