摘要
为了较为合理、定量地分析地下金属矿山采矿扰动影响范围及采矿扰动对地面构筑物的影响程度,结合花岭沟铁矿工程实例,提出了运用Micromine创建地质体真三维模型,采用六面体离散技术对地质体模型进行网格划分,通过耦合技术采用C语言编制转换程序,在FLAC3D中实现了地质体数值模型的重建,在此基础上分析了地下采矿扰动影响范围及对地表尾矿坝安全稳定性影响。研究结果表明:1)采用耦合技术能够创建出较为复杂的地质体三维力学计算模型;2)采用数值计算方法能够较为准确地圈定采矿影响范围;3)采用此项技术能够从定量的角度分析地下采矿扰动对地表构筑物的安全性影响。
To analyze the mining disturbance influence scope in underground metal mine and its influence degree on ground structures more reasonably and quantitatively, combined with engineering practice in Hualinggou iron mine, we proposed that using Micromine to create true three-dimensional geological model in this paper, using hexahedral discrete technology to mesh the corresponding geological model, and using coupling technology and C language to reconstruct the numerical model in FLAC^3D. On this basis, we analysed the influence scope of underground mining disturbance and its influence de- gree on ground tailings dam. The results show that, first, using coupling technology can create more complex three-dimensional geological model. Second, using numerical calculation method can delineate mining influence scope accurately. Finally, using this technology can analyze underground mining disturbance influence on ground structures in the quantitative view.
