The invention discloses a hybrid power system of a mining dump truck, and belongs to the technical field of engineering machinery power systems. The system comprises a generator and a 24V storage battery, and the generator is in control connection with a traction motor; the generator is connected with a rectifier module; the rectifier module is connected with an inverter module, and an energy storage battery is connected in a circuit from the rectifier module to the inverter module; the inverter module is connected with the traction motor; and a shore power charging interface is connected with a filter which is connected with the rectifier module. The braking energy of the traction motor is fully utilized to charge the energy storage battery, the energy of the energy storage battery can be fully utilized to provide power during traction, and carbon emission is reduced; when the generator is abnormal, the vehicle can run to a maintenance warehouse as soon as possible through the energy of the energy storage battery, and traction of other vehicles is not needed; and when an air temperature is low, the 24V storage battery feed condition occurs in a mine car shifting period, and a car cannot be started, the problem can be avoided through a photovoltaic cell panel.
