摘要
结合某地下稀土矿山工程实例,提出了一套融合地形信息、地质信息和力学信息的集成技术.充分利用地表、地质基础数据,在DIMINE可视化建模平台上构建复杂地质体精细化三维模型,结合初拟的采场结构参数完成采场单元划分,通过.dxf文件导入MIDAS软件平台完成各地质体和拟定采场的三维网格划分,利用接口程序实现网格与FLAC^3D力学模型的无缝转换.综合运用Mathew稳定图法和集成技术对初步拟定的两种开采方案形成的空场进行稳定性评价,结果表明Mathew稳定图法与数值模拟结论相一致.
Combined with an underground rare earth mine engineering example,a set of integration technology integrating topographic information,geological information and mechanical information is proposed.A refined three-dimensional model of complex geological bodies is built,and the stope unites are divided according to the initially proposed stope structural parameters by making full use of the surface and geological basic data on the DIMINE visual modelling platform.The three-dimensional grids of local plastids and proposed stopes are divided by importing models into MIDAS software platform through dxf files.Grids are seamlessly converted into FLAC^3D mechanical model by using interface program.The stability of the empty field formed by the two mining schemes initially drawn up is evaluated through the comprehensive application of Mathew stability diagram method and integration technology.Results show that the Mathew stability diagram method is consistent with the numerical simulation conclusion.
