The invention relates to the technical field of double-pressure impact breaking hydraulic control, in particular to a double-pressure impact breaking hydraulic system which comprises an oil tank, an oil suction filter, a ball valve, a motor pump, a pressure pipeline filter and a pressure reduction overflow valve, and the oil suction filter, the ball valve, the motor pump, the pressure pipeline filter and the pressure reduction overflow valve are sequentially connected. The pressure reduction overflow valve is connected with the impact rack control module through a first electromagnetic directional valve, the first electromagnetic directional valve is connected with the box body control module through a second electromagnetic directional valve, and the second electromagnetic directional valve is communicated with the oil tank. The problems that in the prior art, the structure has the high requirement for the stability of a hydraulic system, and the maintenance cost of the system is high are solved. 本发明涉及双压力反击破
