FIELD: mining, machines which completely free the mineral from the seam by slitting, particularly cutter-loaders provided with two auger executive tools spaced apart large distance.
SUBSTANCE: method involves preparing cutter-loader and support units; moving cutter-loaded to central breakage face section; moving face conveyer flight part; returning cutter-loader; supplying support units and supporting roof over cutter-loader; moving cutter-loader in extreme position so that the first executive tool enters drift joined to breakage face; preparing cutter-loader by removing the second executive tool from opposite drift side or arranging thereof in transport position; installing the first executive tool in lower position. Face conveyer flight is moved along the full breakage face length, namely in frontal manner. Cutter-loader is moved in central part of breakage face along with bottom massif bank cutting and kert forming, wherein the kert extends for length of not less than cutter-loader length. Then cut coal is loaded on conveyer. After cutter-loader return the second executive tool is installed in place or moved in working position.
EFFECT: increased efficiency of gently sloping coal bed development due to provision of cuter-loader self-sumping during front movement of face conveyor.
