METHOD BY PROFESSOR KARIMAN FOR RECOVERY OF METHANE FROM DEVELOPED COAL BEDS BY PRODUCTION OF COAL IN LARGE BLOCKS AND THEIR GRINDING IN GRINDING CHAMBER
FIELD: mining.;SUBSTANCE: method includes installation of gas discharge pipes along general shaft ventilation lines and suction of methane from an insulated grinding chamber. Large coal blocks are ground in a grinding chamber upon their delivery there from lava. When coal blocks are damaged, the main quantity of methane contained in them is released and accumulated in a gas-accumulating cavity of a grinding chamber. From this cavity methane is sucked along a gas discharge pipeline to the surface for recycling. The grinding chamber is installed outside the borders of movement of a fresh air jet sent to ventilate second working.;EFFECT: higher efficiency of a developed bed by methane.;2 cl, 10 dwg
