description The utility model relates to a mine hydraulic support setting load keeps system. Current hydraulic support's setting load keeps system energy consumption height, life -span to hang down, and for this reason, this mine hydraulic support setting load keeps system includes that a plurality of setting loads keep the control unit, and it includes PLC, pair hydraulically controlled check valve, hydraulic pressure liquid supplementation device, pressure sensor and automatically controlled valve. Every hydraulic pressure liquid supplementation device includes that one eight channel selection switching -over valve and an asymmetric disjunctor piston machine construct. The utility model discloses utilizing pump station high pressure liquid that the colliery is always ready as settings such as power supply and the original PLC of hydraulic support in the pit, only having increased by one eight channel selection switching -over valve and an asymmetric disjunctor piston machine and constructed, just can keep in the preset
