Aerodynamic gangue combined filling device

The utility model relates to coal mining equipment and a coal mining method for managing a roof by a gangue filling method. The utility model relates to a filling device, in particular to an aerodynamic gangue combined filling device. The device comprises a rail gate road (namely a material conveying roadway of a stope face), a belt gate road (namely a coal conveying roadway of the stope face) andthe stope face, a bracket top plate is fixedly mounted at the top of the stope face through an anchor rod; a hanging belt of which the head end and the tail end are connected with the rail gate roadand the belt gate road is arranged below the bracket top plate; a plurality of coal mine hydraulic brackets are mounted on the front side of the hanging belt at intervals; the hanging belt is fixed behind the hydraulic supports for the coal mines, and a high-pressure wind power device used for blowing gangue conveyed on the hanging belt into a goaf of a working face behind the tail beams of the supports is installed below
