The invention relates to a drive-by-wire full-hydraulic steering system for an unmanned mining vehicle. A laser radar sensor, an angle sensor and a torque and angle sensor are connected to an electronic control unit, the electronic control unit, the electronic control unit is connected with a drive-by-wire steering motor, and the drive-by-wire steering motor is connected with the full-hydraulic steering system; the laser radar sensor is arranged at the front end of the frame, front obstacles in the running process of the vehicle are recognized through the laser radar sensor, the laser radar sensor transmits sensed position information and obstacle information to the electronic control unit, and the electronic control unit controls the steering motor to adjust the steering angle. The adjustment of a driving route and the avoidance of obstacles are realized; the torque and angle sensor is arranged on the steering column of the full-hydraulic steering system; the torque and angle sensor collects the rotation angle and torque of a steering wheel, and the angle sensor is arranged on a vehicle front axle close to wheels, converts the rotation angle of the wheels in the driving direction into an electric quantity signal and transmits the electric quantity signal to the electronic control unit.
