Abstract: In view of the maintenance difficulties caused by dense roadway, weak rock column and strong mining influence in deep panel, the application research of "unloading control coupling" advanced control technology is carried out for 1305 (upper) working face of Hudi coal mine and its corresponding panel roadway. When the cutting height is 30m, the reasonable cutting position is 30m ahead of terminal mining line location through numerical simulation, and the cutting construction technology of deep hole blasting is given. At the same time, the zoning coupling advance reinforcement control technology is adopted to strengthen and support the main roadway in the panel through 7.3m and 5.3m long medium length anchor cables and 10.3M long anchor cables, together with No. 20 high-strength trough steel beam and reinforcement mesh, so as to enhance the overall firmness of the surrounding rock of the main roadway in the panel. After the application of "unloading control coupling" advanced control technology in panel roadway, the deformation of surrounding rock of lane 1103 is greatly reduced, the stability of surrounding rock is significantly improved, and the reliability of support structure is guaranteed.
