采用Flac2D分析断层带高应力软岩巷道围岩稳定性

here are a lot of complex geological structures in the east mining area of Quandian mine.The east main railway roadway and the east main haulageway belong to the typical roadway in the fault zone.Meanwhile the east main roadways are the typical high stress and soft rock roadway under the influence of the roadway's depth and the surrounding rock's lithological character. Then the roadway generates strong deformation and failure. The roadway is the difficult point and focal point. Foucs on the high stress and soft rock roadway in fault zone, the paper makes use of the mohr-coulomb's constitutive model to make numerical simulation with Flac2D. Then the paper processes the caculating results and makes analysis about the data of the monitoring point from the deformation of the roadway. It is beneficial to analyze the the high stress and sofr rock stability of the surrounding rock in fault zone,so it guides the supporting design of the roadway.
