针对某大型地下金属矿山存有大量复杂边界矿柱的工程实际,为了优化设计复杂边界矿柱回采崩矿方式,结合CMS精密探测技术,运用矿山三维建模软件SURPAC对复杂边界矿柱进行了三维可视化建模.在此基础上,构建了复杂边界矿柱的块体模型,并导出其数据文件,采用接口程序将其导入数值分析软件FLAC3D中,实现了复杂边界矿柱数值模型的快速准确构建.模拟分析了后退式侧向崩矿和水平上向分层崩矿2种可行的回采崩矿方式,结合模拟过程中矿柱及充填体的力学响应特征,实现了复杂边界矿柱回采崩矿方式的数值优化.
In order to optimize the design of complex pillar mining with complicated boundary pillars in a large underground metal mine, combined with the sophisticated detection technology of CMS, the complex three-dimensional Visual modeling.On this basis, the block model of the complex boundary pillar is built and its data file is derived and imported into the numerical analysis software FLAC3D by using the interface program, so that the numerical model of the complex boundary pillar can be quickly and accurately constructed Two kinds of feasible mining methods of reclamation of laterally collapsed ore and horizontally upward stratified collapse were simulated and analyzed, combined with the mechanical response characteristics of pillars and backfill in the simulation process, Numerical optimization of the way.
