The invention relates to a double-gearbox hybrid power mine car and a control method. The double-gearbox hybrid power mine car comprises an electric drive system, wherein the electric drive system isconnected with a motor I, a motor II and a storage battery; the motor I is connected with a gearbox I through a transfer case; the transfer case is further connected with an engine and a hydraulic pump; the motor II is connected with a gearbox II; the gearbox I and the gearbox II are connected with a gear drive box; and the gear drive box is connected with a drive axle. The control method comprises four operation working conditions of a starting stage, an acceleration stage, a high-speed stage and braking. According to the double-gearbox hybrid power mine car, the rotating speed of the engineis regulated by the motor I, the engine works in a high-efficiency interval, and meanwhile, braking energy can be recycled; the gearbox I, the gearbox II and the gear drive box are connected controllably and are matched flexibly; the electromagnetic characteristics of the motors are reasonably utilized, and the torque of the car in a low-speed interval is increased; and the battery capacity is scientifically matched with the operation characteristics of the car, and the dead weight of the car is not additionally increased.
