Abstract In this paper, the large deformation damage in the 7608 air return roadway of Wuyang Mine of Lu'an Group was taken as the object, and the overall deformation damage of the roadway was obvious through the site investigation. Combined with the actual geological conditions of the return roadway, constant resistance large deformation anchor / cable + steel belt + steel mesh coupling support coupling support scheme was adopted, from the roadway repair, with good repair results and reference for similar roadway.
