A wheel edge driving system of an electric mining dump truck comprises a gearbox and a planet row which is arranged on the periphery of the gearbox and fixed to a driving wheel. The multi-motor input assembly is used for dynamically coupling the three motors, the first gear shifting assembly has a two-gear speed changing function and is connected with the first multi-motor input assembly, the output shaft is used for transmitting power to the planet row, the second gear shifting assembly is assembled on the output shaft, and the output shaft is connected with the input end of the planet row. The output shaft is in transmission connection with the first multi-motor input assembly along with gear shifting of the second gear shifting assembly or is in transmission connection with the first gear shifting assembly along with gear shifting of the first gear shifting assembly. The complex terrain adaptability is improved, the power requirements of various working conditions are met, switching between a low-speed large torque mode and a high-speed energy-saving mode is achieved, and the optimal matching of the dynamic property and economical efficiency of the whole vehicle is achieved. The invention further provides a gear shifting driving method of the wheel edge driving system of the electric mining dump truck and the electric mining dump truck.
