The invention discloses a driving motor cooling system of a pure electric mining dump truck, which comprises a vehicle control unit VCU, a radiator, a water pump and a driving motor, and is characterized in that the radiator is provided with a fan and a fan controller, the driving motor is provided with a heat exchanger and a motor controller, and the water pump is provided with a water pump controller; a water outlet of the radiator is connected with a water inlet of the water pump through the radiating pipeline, a water outlet of the water pump is connected with a water inlet of the heat exchanger through the radiating pipeline, and a water outlet of the heat exchanger is connected with a water inlet of the radiator through the radiating pipeline. The VCU is connected with the fan controller and the water pump controller through signal lines, and the VCU and the motor controller are connected with the control bus. The invention further discloses a control method of the driving motor heat dissipation system of the pure electric mining dump truck. The method can prevent the fan from oscillating at the critical temperature value, prolongs the service life of the fan, and improves the reliability of the system.
