The invention provides a pure-electric driving axle system for an underground heavy-load mine vehicle, and belongs to the technical field of mine machines. The system comprises a battery pack, a controller, an electric motor, a two-gear planetary gear type transmission, a main transmission, a differential mechanism, a hub reduction gear and a driving axle shell. The electric motor is located at the initial end of a driving system, and energy comes from the battery pack. The two-gear planetary gear type transmission is of a single-stage planetary gear row structure, the power transmission direction is changed through an internal clutch, and different transmission ratios are generated; the main transmission and the differential mechanism are of traditional conical gear structures; the hub reduction gear is of a two-stage planetary gear row structure and is connected with the differential mechanism through a high-speed-stage sun wheel shaft; and a brake and the hub reduction gear are of an integral structure, and brake force is generated by braking a two-stage sun wheel. Through the driving system, a series of simple mechanical structures are designed, an engine is omitted, the problem of mine underground environmental pollution is solved, and the working efficiency and safety are further improved.
