The utility model discloses a JKMD type mine hoist with a brake torque monitoring function. The JKMD type mine hoist is composed of a motor, a hoist rotary drum, a disc type braking system and a brake torque monitoring device; the brake torque monitoring device is composed of a pressure sensor, a signal transmitter, a PLC (Programmable Logic Controller) and a displayer which are electrically connected; the pressure sensor is embedded in an oil cylinder of the disc type braking system and is used for transmitting a pressure signal of the oil cylinder to the PLC; and then the oil pressure in the oil cylinder is monitored at any time through the displayer. As the mine hoist is provided with the brake torque monitoring device, the brake torque of a disc-type brake can be accurately monitored, and when the brake torque is not in a specified range, an alerting signal can be given out, thereby providing scientific basis for maintenance personnel to adjust the closing gap of braking oil pressure, taking preventive me
