COAL CONTAINING ROCK IN THE COAL CONTAINING ROCK FACE SEPARATION AND USE METHOD Russian patent published in 2019 - IPC E21C41/18 

FIELD: mining.

SUBSTANCE: coal containing rock in the coal containing rock working face coal separation and use method, used for the coal containing rock separation and use, produced in the face with coal containing rock, with the several coal beds simultaneous development using the very thin coal bed as the protective formation. Directly under the ground locating the underground transportation, accumulation and filling system of draw rock; extracted from the coal-containing rock face the large amount of coal containing coal is delivered to the underground chamber for separation and enrichment in order to implement the coal containing rock highly efficient separation; separated draw rock after crushing is filled into the protected formation protected space; since draw rock is not extracted from the well, then the environmentally safe development is performed with the protected formation laying and caused by the several coal beds simultaneous development surface subsidence is effectively prevented; the separated industrial product by means of the main transport system is delivered to located on the surface electric power plants using the industrial product for the electricity generation; power plants are effectively operating and reduce requirements to the coal from mines quality, which provides for reduction in the commercial coal average ash content and the selling price increase.

EFFECT: simultaneously with the coal-containing rock highly efficient separation the coal and rock highly efficient use is performed, economic efficiency and social benefit are obvious and there are good possibilities for implementation.
