The MG750/1860-WD coal mining machine equipped with the 5312 working face in Baodian Mine had electrical faults from time to time. In view of this situation, the principle of this coal mining machine was analyzed, 4 aspects of coal mining machine mainframe not starting, rocker arm not lifting normally, inverter not getting power after drafting, coal mining machine traction were discussed, with fault analysis, treatment measures were elaborated and summarized. Since the practical application, the causes and treatment measures of these common fault points were clearer, and the operation efficiency of the equipment was significantly improved.
