The invention provides a mining dump truck heat dissipation system which comprises a hydraulic heat dissipation system, the hydraulic heat dissipation system comprises a heat dissipation reversing valve set and a hydraulic system heat dissipation device, and the oil return end of a lifting oil cylinder is divided through a first transition block to form a first oil return pipeline and a second oil return pipeline which are both communicated with an oil tank. The second oil return pipeline is provided with a temperature sensor, a hydraulic system radiator and a wet bridge, the heat dissipation reversing valve set comprises a heat dissipation main valve and a pilot electromagnetic valve, when the heat dissipation main valve opens a first channel, hydraulic oil enters the hydraulic system radiator for heat dissipation and then enters the wet bridge, and when the heat dissipation main valve opens a second channel, the hydraulic oil directly enters the wet bridge; the hydraulic system radiator comprises a fan, and a silicone oil clutch controller is connected between the fan and the engine. According to the heat dissipation system of the mining dump truck, the silicone oil clutch controls the fan, and the heat dissipation reversing valve set is arranged, so that the energy consumption of the whole truck under the cold working condition is reduced, and the temperature of a hydraulic system of the whole truck under the high-temperature working condition in summer can be controlled.
