The invention relates to a comprehensive mechanized coal mining method through a cantilever support, which organically combines a shearer, a scraper conveyer, a cantilever support and a hydraulic breaking-off prop for combined operation. The shearer is started to cut the coal wall, and the cut-off coal automatically falls on the scraper conveyer; the scraper conveyer is started to automatically convey the coal out; when the shearer cuts the coal wall to a certain depth, an expansion link of a jack is pushed to extend out, the hydraulic breaking-off prop is used as a fixed fulcrum, and the scraper conveyer and the shearer arranged thereon are together pushed towards the coal wall; the hydraulic breaking-off prop is disassembled and separated from a top plate, a piston rod of the jack is pushed to draw back, the scraper conveyer is used as the fixed fulcrum, and the hydraulic breaking-off prop is pulled forwards; and the cantilever support moves forwards through a hydraulic operating mechanism ...
