摘要
在矿山安全生产建设中,对井下空区进行探测、对空区安全性及地表移动规律等进行分析评价,以及制定科学合理的空区处理方案非常重要,这对延长矿山现有资源的开采年限,为矿山的安全高效开采制定科学的开发利用方案具有重大的现实意义.应用空区探测系统(CavityMonitoringSystem,简称CMS),精确地获取地下矿山采空区的三维形态和准确的空间位置,并借助大型三维矿床软件DIMINE建立起了空区的三维形态模型,通过耦合方法实现在FLAC3D中生成能准确反映空区和围岩地质结构及岩性条件的数值模型,简化复杂空区稳定性计算的结果,并提高了准确性和可靠性.结果表明,使用地质模型转换的数值计算模型,对采空区稳定性进行了成功的模拟,并证明采用"地质-数值"耦合方法的方法对采空区稳定性研究是可行的.
In safety production and construction of mine, it is very important to detect the underground space and analyze the surface movement area safety rules, as well as to formulate a scientific and rational treatment options in mined-out area. There are great practical significances that extend the exploitation existing resources of mine life and formulate a scientific development and utilization of the program for the safe and effieient exploitation of mineral frame. With the empty area detection systems （Cavity Monitoring System, referred to as CMS）, it precisely accesses to underground mine mined-out area and accurate three-dimensional shape of spatial location, and with large-scale three-dimensional software DIMINE deposits built up an empty area of the three-dimensional shape model, through the coupling method in generating can accurately generate the surrounding the lithologic conditions and geological structures zone on FLAC^3D, simplify comphcated numerical model zone stability calculation results, and improve the accuracy and reliability. The results showed that the use the numerical calculation model of the geological model transformation, the stability of mined-out area had a successful simulation, and proved that a ＂Geology - Value＂ method of coupling method to the stability of mined-out area is feasible.
