FIELD: mining.
SUBSTANCE: method consists in simultaneous extraction with cuts and in transfer reloading of overburden into worked out space on three horizons divided with beds of mineral. Also the first dragline is assembled on the roof of an upper production bench to transfer rock of an upper stripping bench onto working platforms of lower production horizons by upper excavating and at withdrawing run. The second dragline is assembled on the roof of the lower production bench for final forming of internal dump, mining of the second and third stripping benches and for pile of re-excavation with an advance run.
EFFECT: increased efficiency of deposit development and of stripping equipment operation; facilitation of reliable operation of production excavators.
