The invention discloses a full-mechanized filling and coal-mining hydraulic support. The ull-mechanized filling and coal-mining hydraulic support mainly comprises a face guard, a front canopy, a front top beam, a middle top beam, a rear top beam, a front upright post, a middle upright post, a rear upright post, a four-bar mechanism, a cut and fill mining conveyor, an adjusting jack and a base. The rear end of the middle top beam is hinged with the rear top beam for drawing coal; a rail for the cut and fill mining conveyor to slide forwards and backwards is arranged on the bottom ends of the middle top beam and the rear top beam; a pushing and pulling oil cylinder for raising or dropping the rear top beam is arranged between the middle top beam and the rear top beam; the rear top beam comprises a box body, wherein a drawing and pulling box matched with the box body is arranged inside the box body; a hydraulic cylinder which is connected with the inside of the box body is symmetrically arranged inside the drawing and pulling box; a drawing and pulling plate is arranged on the box body; a coal carving machine is arranged on the drawing and pulling plate; and a pushing and pressing plate is arranged on the front end of the rear top beam. The device not only can support the fully-mechanized caving and mining surfaces, but also can completely fill normal coal caving and milling regions of the bracket, so that coal caving and filling cannot affect each other. The bracket has simple structure, strong adaptability and operability, good filling effects, and extensive practicability.
