In order to solve the technical problems of deep shaft high-stress roadway deformation and serious support difficulties, the numerical simulation and industrial tests were used to analyze the deformation law and support parameters of the surrounding roadway in 7608 working face of Wuyang Mine. The results showed that with the intensification of mining, the discontinuous deformation and asymmetric deformation of the surrounding rock of the roadway were also gradually intensified. After adopting the new support scheme, the deformation of roadway roof, floor and two sides finally stabilized at 240mm and 320mm, it showed that the combined support scheme of anchor, net and cable can effectively control the deformation and failure of roadway surrounding rock.
