FIELD: mining.
SUBSTANCE: proposed method comprises preparatory jobs, ply-by-ply stoped excavation with setting of barren formation seam on worked oil behind the mole. Working is performed with the help of mole of various operating principles. First, stope is subjected to through ventilation. For this, said stope is subjected to first cut by the mole over its entire length for communication with vent gateway. Separate ply-by-ply excavation of potash seams is made by selective, continuous or cyclic miner is executed. First, bottom productive zone of the bed is excavated and loaded into self-propelled car. Miner returned to initial position, started is excavation of barren formation seam to be left at stope soil. Thereafter, left productive formation seam is excavated and located into self-propelled car to be displaced to mine transportation means.
EFFECT: higher efficiency of ore mining.
