The utility model discloses a PLC (programmable logic controller) control system of a mine-used winch, which is characterized in that a bus is sequentially connected with a system control cabinet (1), a driver control console (2), an ET-200m module (3), a transmission device (4), an S7-300 PLC (5), a detection instrument (6) and another driver control console (2), wherein the S7-300 PLC (5) is connected with a programmer (7), and is also connected with a human-computer interface (HMI) operator station (2) through industrial Ethernet. The PLC control system has the benefits of good speed regulation property, high speed regulation accuracy, capability of four-quadrant operation, and fast forward and reverse operation, fast dynamic response speed, accurate braking and positioning functions, and high requirement for reliability, and in addition, the PLC control system reduces the functional invalidity rate of various mechanical and electric original pieces, and avoids accidents occurring during working of operato
