Abstract In order to successfully withdraw the equipment and hydraulic support of No. 8119 fully mechanized caving face in Baidong Mine, it was necessary to lay artificial roof at the end of mining stage. Aiming at the problems of high cost and poor safety of metal mesh with hydraulic support materials, a scheme of laying flexible mesh, anchor rod and anchor cable to fix wire rope was proposed. The flexible mesh was used to replace the traditional metal mesh and simplify the networking process. The results showed that the scheme accelerated the online speed, shortened the construction period, reduced the labor intensity of workers, improved the safety factor, and ensured the safe withdrawal of equipment and hydraulic support, which provided reference for the final mining stage of other working faces in the mine.
