The invention discloses a hydraulic bracket and a method for drawing, filling and mining at a high position. The hydraulic bracket for drawing, filling and mining at the high position comprises a front top beam, a middle top beam and a rear top beam, a front canopy arranged on the front part of the front top beam, a face guard arranged on the front end of the front canopy, an upright post supporting the top beams, a base, a coal drawing hole arranged on the middle part of the middle top beam, a spraying and dust-settling device and front and rear check curtains outside the spraying and dust-settling device, a rear scraper conveyor arranged on the base below the coal drawing hole, a coal guide plate arranged on the two sides of the rear scraper conveyor, and a filling and pushing device arranged on the tail part of the base, wherein the spraying and dust-settling device and the front and rear check curtains are arranged on the two sides of the lower coal drawing hole of the middle top beam. The device not only can support fully-mechanized drawing and mining surfaces, but also can completely fill a goaf and achieve normal coal drawing of the bracket. The coal drawing and filling operations are completely spatially separated, and the bracket is simple in structure, strong in adaptability and operability, easy in operation, good in filling effects, and extensive in practicality.
