| 摘 要： | 对FLAC3D的自带Mohr-Coulomb模型进行了修改,利用VC++6.0编译出Frac.dll。利用现场煤体采动裂隙观测结果作为初始裂隙状态,对采动裂隙扩展、交叉过程进行全程模拟。同时对此过程中的瓦斯流动情况进行研究。通过与现场实测数据对比,模拟结果与实测值不仅在数值上符合较好,而且分布规律和变化趋势也很一致。

| Abstract: | Mohr-Coulomb model of FLAC3D is modifined.The Frac.dll is complied with VC++6.0.With field observation data as initial state,the mining-induced fractures extension and cross are simulated.And the gas flow is researched in this process.Compared with the in-situ results,simulation results are proved to be almost consistent with the test in-situ not only in data but in the law of location and the trend of change. |
