FIELD: oil and gas industry.
SUBSTANCE: method involves drilling of coal bed with main inclined workings, preparation of extraction pillar along the strike, extraction of strip in iron-ore interlayer with cutter-loader at its straight movement, extraction of coal strip at reverse movement of the above cutter-loader, transportation of broken-down coal and rocks of interlayer along mining face with drag-type face conveyor, with belt conveyor transport along areal working and to surface with various main line transport means. Flow of iron-ore rocks of interlayer is subject to screening and crushing, drying and heating to temperature over condensation temperature of water vapours with water vapour during certain time in spiral chute. Then, electromagnetic separation of dried flow of iron-ore rocks of interlayer is performed with supply of coal component to broken-down coal flow, and waste water vapour is supplied for repeated use.
EFFECT: invention allows increasing efficiency of selective development.
