Aiming at the asymmetric deformation phenomenon of surrounding rock in deep mine roadway after excavation, proceeded with mechanics model building and numerical simulation analysis of different partitions of roadway surrounding rock deformation and failure of rock mass beam has been made based on the theory of structural mechanics. The bending moment and deflection equations of the partitioning rock beam deformation calculation has been concluded, and obtained the maximum bending moment position and deflection position of regional rock mass beam by theoretical analysis. Simulation results validated the building of mechanical model effectively, drawn the risk position of each rock beam, this study can provide a theoretical reference on relevant issues.
