The invention discloses a novel mining axle which comprises an axle housing, a first parking brake, a second parking brake, a first driving motor, a second driving motor, a first wheel edge brake assembly, a second wheel edge brake assembly, a first wheel edge speed reducer assembly and a second wheel edge speed reducer assembly. The first parking brake, the first driving motor, the first wheel-side brake assembly and the first wheel-side speed reducer assembly are sequentially and axially arranged along one side of the center of the axle; the second parking brake, the second driving motor, the second wheel-side brake assembly and the second wheel-side speed reducer assembly are sequentially and axially arranged along the other side of the center of the axle; each hub reduction gear assembly comprises a half shaft assembly, a first-stage planet row assembly and a second-stage planet row assembly, and a second-stage sun gear of each second-stage planet row assembly is meshed with the end of a first-stage planet carrier of the corresponding first-stage planet row assembly. A double-motor and double-stage hub reduction driving scheme is adopted, the power transmission route is short, the transmission efficiency is high, and the bearing capacity is high.
