FIELD: mining industry.
SUBSTANCE: method includes extracting quarry to planned depth by ore and rocks extraction by displacement of shelves along horizons with transferring to crushing plants, crushing rocks and then delivering them by lifting device to the surface, during extraction of quarry to planned depth at first stage during construction of board at the end of quarry in zone of decrease of power of deposit in stable rocks conveyer rope system is constructed, connected to hoisting machine, to bed with recesses, allowing to raise crushed material to large height at steep angle and with deepening of mining and displacement of crushers to lower horizons conveyer system is extended to provide for optimal transport shoulder for gathering vehicles.
EFFECT: higher efficiency, higher productiveness.
