摘要:
以某矿107工作面顺槽为依托,完成了锚杆(索)支护参数设计和FLAC数值仿真分析,分析了受工作面动压影响回采巷道围岩的变形规律,设计了现场监测方案,开展了围岩动态变形规律现场研究。FLAC模拟和现场监测结果表明:受动压影响的厚煤层中回采巷道围岩变形距工作面不同距离可分为小变形、中变形和大变形三个不同区段,对于不用的变形区段应采取针对性的支护措施,以保证围岩的整体稳定性。
Abstract:
Abstract: Based on gate-way roadway of a colliery 107 mining face, the basic parameters of combined supporting design scheme of anchor and cables was ascertained and FLAC numerical simulation was completed. Dynamic deformation law affected by dynamic pressure of surrounding rock of mining roadway was analyzed with theoretical method. After designing monitoring scheme of deformation, field study on dynamic deformation law was executed. The results of FLAC numerical simulation and field monitoring showed that the deformation surrounding rock of mining roadway was divided into three sections with deformation and distance between roadway cross-section and mining face. They are little deformation, middle deformation, and large deformation. Different support measures should be executed on these sections in order to keep gate-way roadway global stability.
