FIELD: mining.
SUBSTANCE: method includes mining of an inclined capital trench, installation of bottomhole and manifold conveyors, excavator mining of stripping rocks, extraction of a mineral with ledges, and internal piling by means of a wedge-shaped cut. Mining of stripping rocks and extraction of a mineral are carried out with permanent width of the excavator bottomhole along the entire front of works, at the same time the width of the excavator bottomhole is adjusted by the angle between the upper border of the bottomhole and the contour of the adjacent cut.
EFFECT: reduced labour intensiveness of works, higher efficiency of mineral reserves extraction, stable efficiency of a loading-transport complex and safety of mining works.
