FIELD: mining industry, possible use in deep quarries extracted with utilization of motor and conveyor transport. ^ SUBSTANCE: method includes transportation of rock mass from excavation faces by dump trucks and loading it through mobile crusher plant, mounted at temporarily shut down section of quarry, and transit ribbon conveyor, located in the mine on end side of quarry, onto ribbon conveyor lift, positioned in mines on end side of quarry. After update of quarry with positioning of mobile crusher plant at temporarily shut down section of quarry side, transit conveyor is disassembled, crusher block from mobile crusher plant is moved and mounted above end section of conveyor lift, in semi-trench driven preliminarily to subjacent safety bench a bunker is assembled with plate feeder for loading crusher block, while block of rocks formed below previous locations of mobile crusher plant and dump truck unload points is extracted with transportation and loading of exploded rock mass from dump trucks and rotary platform of main ramp through bunker with feeder and through crusher block from mobile crusher plant. ^ EFFECT: no need for moving crusher plant and for additional motor transport unit between crusher plant and conveyor lift. ^ 2 dwg |
