巷道过断层破碎带施工技术研究

巷道围岩塑性区的破坏范围和围岩变形量在断层破碎带较为严重,对南阳煤业公司3206工作面轨道顺槽断层带采用FLAC^3D软件进行数据模拟,在过断层时采用锚索网、注浆加固、支棚等技术措施方案。监测结果表明:该过断支施工技术方案能有效地减小巷道围岩的变形量,提高巷道稳定性。

Study on the Construction Technology of Roadway Passing Through the Fault Fracture Zone

The scope of damage and deformation of surrounding rock in the plastic zone of roadway surrounding rock are relatively serious in the fault fracture zone.The FLAC3D software is used to simulate the fault zone along the channel of 3206 working face of Nanyang Coal Industry Company,and the technical measures such as anchor cable net,grouting reinforcement and supporting shed are used when passing through the fault.The monitoring results show that the construction technology can effectively reduce the deformation of the surrounding rock and improve the stability of the roadway.
