[0013] The present invention is a method for supporting the anti-collapse roof panel. First, when the cut hole is opened in the working face, the cut cut section roof of the entire working face is pre-laid and connected with a metal net with a fixed specification of 5.0m×1.0m. The net material is 10# iron wire, the mesh is diamond-shaped braided holes, the mesh is 0.04m×0.04m, and then the hydraulic support is installed in the cut hole, and the hydraulic support top beam is against the direct roof to ensure that the length of the connected metal mesh can hang in front of the support coal wall. And use the hydraulic support protection board against the coal wall; when laying the net, first unfold the net along the working surface, and then connect with the front net of the hydraulic support in turn. The overlap of the metal net shall not be less than 200mm, and the double strand 16# iron wire...
