This machine power is big, the multi-electrical machinery crosswise arrangement, the complete machine structure is compact, uses the exchange frequency conversion velocity modulation system, the frequency conversion velocity modulation uses aircraft-borne -like. Cuts the electrical machinery, the pulling motor and so on main part to be possible to extract from the worked-out section, easy to replace, facilitates the service. The pulling motor outputs torque decelerates after the third-level cylindrical gears and the second-level planet gear reduction gear, by the planet carrier outputs, with walks lining on the feet and palms of buddha meshing through the driving gear, by walks again round and on working surface scraper conveyers rack rail meshing causes the coal mining machine back and forth to walk, simultaneously the brake spindle output shaft is connected through the key and the brake, realizes the electricity hauling department brake. About the hauling department, the middle electrically controlled boxs joint stud, the positioning pin, the rocking shaft sells the axis four groups with
