Room goaf end flexible filling reinforcing device and method

The invention belongs to the technical field of mine filling, and provides a chamber goaf end flexible filling reinforcing device and method.The device comprises two guide rails, a suspension part, guide wheels and a traction device, the two guide rails are installed on the two opposite side walls of an upper chamber respectively, the guide wheels are arranged at the two ends of the suspension part and installed on the guide rails, and the traction device is installed on the suspension part; flexible materials are hung on the hanging pieces, the traction device is installed in the rock drilling connection roadway, and the traction rope is connected with each hanging piece. After room stoping is finished, the flexible material is hung into the goaf and dragged by the traction device to slide to the end of the room goaf along with the multiple hanging pieces along the guide rail, then room goaf filling is conducted, and the flexible material and a common filling body at the end of the goaf form a flexible reinf
