METHOD AND FACILITIES TO REALIZE COAL STRATUMS UNDERGROUND DEVELOPMENT Russian patent published in 1995 - IPC

FIELD: mining. SUBSTANCE: coal deposit is opened, prepared and using column system of development stratums treatment is realized. In the case nuclear reactor is mounted in mine to produce steam. Produce steam is subjected to fire overheating, using produced coal burning. Overheated steam is used for electrical power production and condensed heat carrier is sent back into steam production phase. To realize the method complex of facilities for underground development, that has stationary mine equipment and mine inside used main and auxiliary equipment, are additionally provided with nuclear electrical power plant, located on mine surface or underground under depth of water horizons laying, and with boiler aggregate, located directly near steam generator. Boiler aggregate is link with steam generator by steam pipeline and with steam turbine compartment and outlet of the latter is connected with steam generator of reactor by water pipeline. EFFECT: method allows to increase coal production. 2 cl, 2 dwg
