摘要
采用数值模拟法进行实测采空区群稳定性分析存在建模效率低、数值模拟精度差的问题。介绍了一种高效的实测复杂三维采空区群稳定性分析技术,以北辛庄矿区为例,采用Faro激光扫描仪探测采空区群,经3DMine处理生成矿山三维采空区群模型和多组剖面线,再导入Midas中建模,最后在FLAC^3D中进行采空区群稳定性数值模拟。结果表明:基于Faro-3DMine及Midas-FLAC^3D耦合技术能高效的对复杂采空区群进行精细化建模,准确模拟分析采空区群的稳定性,为采空区群治理提供了理论依据。
The stability analysis of goaf group by numerical simulation has the problems of inaccurate modeling and low numerical simulation efficiency.The goaf group of Beixinzhuang mine is taken as an example,the empty area with Faro laser scanner was scanned,and 3D goaf group model of mine was built by 3DMine.The goaf group model and multiple sets of hatching were imported into the Midas model and finally simulated in FLAC^3D.The result indicated that this method can efficiently perform detailed modeling and stability numerical simulation analysis of complex goaf group.It is an efficient method for analysis the stability of complex 3D measured goaf group,which can provide a theoretical basis for the management of gobs.
