Abstract: In response to the problem of excessive local convergence deformation in the inclined coal seam roadway of Pangpangta Coal Mine, with the engineering background of 5-106₂ roadway, the instability mechanism and main causes of deformation and failure of the roadway are analysed and summarized through theoretical analysis and numerical simulation. The response mechanism of surrounding rock deformation to dynamic pressure is explored, and the control mechanism of collaborative support technology with high pre-tension anchor bolts and cables on surrounding rock deformation is revealed. In response to the shortcomings of the original support method, an optimization scheme of collaborative support technology with high pre-tension anchor bolts and cables as the core is proposed. Industrial experiments are conducted in combination with on-site conditions. The research results show that small surface area, low prestress, and non coordinated anchor （cable） support are the main reasons for the poor support effect of the 5-106₂ roadway; for inclined coal seam roadways, vertical dynamic pressure has a greater impact on the two sides, while horizontal dynamic pressure has a greater impact on the roof. Compared with horizontal dynamic pressure, vertical dynamic pressure is the dominant factor affecting the convergence deformation of the roadway; the high pre-tension collaborative support technology can apply uniform high prestress to the shallow surrounding rock of the roadway, ensuring that the surrounding rock is in a relatively stable three-dimensional stress state and effectively improving the stability of the surrounding rock. On-site monitoring shows that after adopting the optimized support scheme, the deformation of the roadway is effectively controlled, without the phenomenon of anchor bolt and cable breakage, and the local mesh phenomenon is suppressed. The on-site support effect is good, providing reference for the deformation control of surrounding rock in coal mine roadways under similar engineering geological conditions.
