Hydraulic support for solid waste cementing and dense filling mining

The invention discloses a hydraulic support for solid waste cementing and dense filling mining. The hydraulic support comprises a support body part, a solid filling aggregate conveying part, a composite filling part and a filling feedback part. The composite filling part comprises a spiral pushing and pressing device and a cementing slurry applying device, the spiral pushing and pressing device is arranged on the base and comprises a sliding seat, a spiral pushing and pressing assembly and a filling isolation vertical plate, and the cementing slurry applying device comprises a cementing slurry conveying pipeline and a filling area grouting pipe; and the filling feedback part comprises an optical fiber stress sensor and a liquid level sensor. The solid filling aggregate is continuously filled and extruded into the goaf through the spiral pushing and pressing device so as to improve the filling compactness of the solid filling aggregate, and then the cementing slurry is applied to the solid filling aggregate fi
