The invention belongs to the technical field of mine anti-explosion rubber-tyred vehicle hydraulic brake systems, and particularly relates to an energy-saving hydraulic brake system of an anti-explosion electric rubber-tyred vehicle. The problem that an existing anti-explosion electric rubber-tyred vehicle hydraulic brake system cannot meet the energy-saving use requirement is solved. The energy-saving hydraulic brake system is independent of a steering system of the anti-explosion electric rubber-tyred vehicle, and comprises a hydraulic pump station, a vehicle driving wet brake, a parking brake, a foot valve and a parking brake valve. The energy-saving hydraulic brake system has the advantages that the problem of the hydraulic brake system can be solved, an intermittent work mode is adopted, automatic starting and stopping are achieved, the service life of an anti-explosion motor and brake hydraulic system is prolonged, the service life of the system is greatly prolonged and the maintenance cost is reduced; a signal of a pressure sensor is connected into a vehicle control system, therefore, the work pressure and fault of a vehicle hydraulic system can be monitored, the anti-explosion electric rubber-tyred vehicle runs in a mine more safely and reliably, and high practicality is achieved.
