摘要

Combined with engineering conditions of the Ⅲ-level south roadway of Yangzhuang Mine, the deformation of surrounding rock and mechanical characteristics of support structure is analyzed by FLAC3D numerical simulation when the roadway is supported by CFSTS support program. The results shows that: For the weak mudstone surrounding rock and complex geological conditions, the deformation of surrounding rock is fast, large and unsymmetrical deformation, the bolt-net-shotcrete support is difficult to maintain the roadway stability. The CFSTS used Φ219 ×8 mm steel tube filled with C50 core concrete, which provides powerful supporting force combined with other roadway support ways and restrict surrounding rock to the roadway space. By FLAC3D simulation analysis shows, the deformation of surrounding rock is small and support structure is mad good use and keep work, which can maintain the stability of roadway.
