FIELD: mining.
SUBSTANCE: method of working out the excavation site includes the excavation of the excavating and ventilating drifts, the chamber mining system, the transportation of the mineral by the conveyor. The excavating drift passes to the middle of the excavation site, then the auxiliary drifts pass at an angle to the excavating drift. The cleaning chambers are worked from the auxiliary drifts. Auxiliary excavation gates pass at an angle of 30-60 degrees to the excavation drift. The cleaning chambers within the excavation site are worked both in the meridional and in the latitudinal direction. The mouth of the cleaning chambers in the latitudinal direction is located diagonally from the mouths of the treatment chambers in the meridional direction.
EFFECT: invention reduces the amount of mining preparation works by reducing the length of the extraction, and the face ends of conveyor, enhance security operations.
