A vehicle-mounted mining electrical system comprises a power battery power supply, an all-in-one controller, a traction power assembly, an auxiliary unit and a low-voltage electric appliance. A high-voltage cable is fixedly arranged along an inner cavity of a vehicle body left girder, the inner cavity structure of the vehicle body girder serves as a shielding structure to reduce electromagnetic radiation interference, a three-phase cable is led out close to the left side and does not exceed the upper surface of a vehicle frame girder, and the inner cavity structure of the left girder serves as the shielding structure to reduce electromagnetic radiation interference. Auxiliary unit power supply lines are all led out from the right side of the all-in-one controller and arranged on the upper surface of the right girder, and a lead-acid storage battery power supply line, a central junction box power supply and backflow power supply line and a communication line are arranged on the lower surface of the right girder and isolated from auxiliary unit power supply through a right girder bending structure; a communication line is connected with a battery management system communication interface, a gearbox controller communication interface and an all-in-one controller communication interface along with a low-voltage power supply line wiring path, and finally enters a cab through a central electrical junction box connecting wire harness to be connected to a whole vehicle controller.
