FIELD: mining.;SUBSTANCE: method to change over cutter-loader with auger actuators to new mining strip with location of face conveyor drive in longwall face and single-sided pattern of extraction, includes movement of cutter-loader with mineral extraction from cutting zone. At the same time at the end section of longwall face, at the distance equal to the distance between axes of cutter-loader augers, two wells are drilled, to the depth equal to one width of cutter-loader grip. Then cutter-loader moves as idle-running to the end of longwall face, afterwards cutter-loader augers are installed along axis of wells, where at frontal feed of cutter-loader, auger hubs enter wells, and auger blades destroy massif and produce mineral to conveyor with subsequent movement of cutter-loader and formation of new mining strip. In another version of method, cutter-loader changeover is proposed with shuttle method of extraction.;EFFECT: higher efficiency of mining faces operation, simplified technology of second working, reduced costs for equipment, less time spent for auxiliary operations, increased resource of conveyor operation, elimination of multiple bends in conveyor stand.;2 cl, 3 dwg
