Aiming at the problem of roadway support under the near coal seam mining goaf area in Mugua Mine, the 10-102 working face was taken as the engineering background, the relevant parameters of roadway support were selected by testing the stress of roadway surrounding rock and analyzing the anchor ability of coal rock layer, and the stress and strain of roadway surrounding rock after roadway excavation and support with FLAC3D software was simulated to verify the reasonableness of the support method. The deformation of the roadway and the stress condition of anchor rod and anchor cable during the roadway excavation and working face retrieval were monitored, and the results showed that the combined support of anchor rod resin extended anchor cable network can meet the requirements of safe roadway excavation and safe and efficient coal mining working face retrieval under the near coal seam mining area.
