The utility model discloses a deep mine high-temperature damage and roadway support combined treatment device. The deep mine high-temperature damage and roadway support combined treatment device comprises vacuum supporting plates, and every two adjacent vacuum supporting plates are fixed through a double-tray anchor rod device. Each double-tray anchor rod device comprises a first tray, a second tray and an anchor rod, wherein the anchor rod is perpendicular to the first tray and the second tray, and an isolating column parallel to the anchor rod is arranged between the first tray and the second tray. Compared with the prior art, the deep mine high-temperature damage and roadway support combined treatment device has the advantages that the problems of the deep mine high-temperature heat harm control and roadway supporting difficulty are solved at a time, the vacuum character of the vacuum supporting plates can isolate heat dissipating of the surrounding rock of a roadway, and other floor plates of the vacuum supporting plates have the high-strength tensile performance and the high-strength compression resisting performance and can support the surrounding rock of the roadway; the vacuum supporting plates are installed through double-anchor-rod disks, after the vacuum supporting plates are recycled, the anchor rod supporting does not lose efficacy, mine high-temperature heat harm control and roadway supporting are combined, and the mine cooling cost and the roadway supporting cost are saved.
