METHOD FOR OPENING AT OPEN DEVELOPMENT OF MINERAL BEDS

摘要

Method for opening at open-pit development of mineral beds includes penetration of inclined mine bores equipped with stationary conveyor lifting units for transportation of mineral and waste rock, gallery penetration, those are discharged by width of excavator cut and placed in the rocks of the foot, hanging walls or at the flanges of the pit and equipped with movable concentration horizons. The gallery being discharged is equipped with movable band conveyor for reloading mineral to stationary conveyor lift. At that the waste rock after the pit comes to designed contour at the sites equipped with concentration horizons is placed to the inner dump in front of the mouth of the gallery discharged before, this is equipped with tubing with formation of a tunnel through which one reinstalls the movable band conveyor in direction of the worked-out and filled space of the pit; at that in the space over the tunnel one forms from tubing additional place for dump formation.
