Based on support difficulty in 1100下 belt roadway working face in Shandong Energy Linyi Mining Industry Group, large span roadway maintenance features were analyzed, the support theory was expounded, combined with geological condition, bolt-mesh-anchor combined support was put forward. The actual measurement on the site showed that roadway deformation was stable after 15 d, roof subsidence reached 250 mm, the two sides distance was less than 130 mm, the amount of floor heave was 80 mm, which demonstrated that the support technology controlled the roadway deformation effectively and ensured the safe mining of the working face.
