Abstract: The complex characteristics of the deformation of the surrounding rocks of double-used roadway with deep excavation-induced damage zone and the destabilization of the roadway along the empty stay are very easy,which seriously affect roadway excavation speed. A case study was performed at the headgate of the 2401 longwall panel at the Shunhe Coal Mine. The damage characteristics and destabilization causes of the surrounding rock of the doubleused entry were investigated. The mechanical deformation mechanism of the thick mudstone roof soft rock roadway was explored. The zoning of different sections along the roadway was delineated. The control countermeasures of the surrounding rock based on the mechanical deformation mechanism were proposed and implemented at the study site.The results show that the deformation damage of the surrounding rock of the double-used roadway was mainly manifested by the diagonal cutting of the roof with large area sinking,non-uniform in-road extrusion of both sides,and shear misalignment projection of the floor heave. High stress environment,thick mudstone roof,non-uniform stress and support failure were the main reasons for the destabilization of the surrounding rock of the roadway. The roadway was divided into three areas:over-head support area,post-frame temporary support area,and stabilized area.A combined support strategy of "pressure relief through roof cutting+ cable bolts + U-shaped steel support" was adopted for the roadway. With this support strategy,the surrounding rock stress was released and cut off. The deformation of the roadway was successfully contained by the cable bolts and the U-shaped steel support. The convergence rate of surrounding rock was less than 10%.
