The invention belongs to the technical field of coal mine roadway tunneling crawler-type carrier application, and particularly discloses a bidirectional driving hydraulic steering brake system which comprises an energy accumulator, a reversing valve, a shuttle valve A, a shuttle valve B, a shuttle valve C, a shuttle valve D, a gearbox steering oil cylinder, a steering pump and a hydraulic oil tankwhich are used in cooperation and connected through pipelines. The steering pump is connected with a diesel engine. A piston rod of the gearbox steering oil cylinder pushes the left steering fork andthe right steering fork respectively, the steering pump is connected with the energy accumulator, and a one-way valve is arranged on a connecting pipeline. The hydraulic steering braking system capable of being driven in the two directions and the working method of the hydraulic steering braking system have the beneficial effects that the system is reasonable in design, efficient and accurate two-way driving control can be conducted on a crawler-type carrier in the coal mining process, the labor intensity is relieved, the working efficiency is improved, and meanwhile control operation is safeand stable.
