Based on poor stability of roadway surrounding rock under special geological condition in sliding structure zone, Yicheng Shan’ao Mining Industry return air roadway was taken as example, observation on the site, numerical simulation were adopted to study roadway deformation features and support technology in sliding broken surrounding rock, asymmetric base angle joint anchor cable anchor supporting technology was put forward, the result showed that roadway asymmetric deformation got good control, improving the whole stability of roadway.
