摘要
根据矿区实测的地应力场和工程地质条件,结合矿山的实际生产情况,采用FLAC3D软件对Ⅴ号矿体-580 m中段采场进行了数值模拟计算,对提出的3种开采方案进行比较,并通过分析开采过程中围岩和充填体的应力,变形及破坏情况,获得了最佳开采优化方案,以期指导类似工程施工。
According to the measured in-situ stress date, engineering geological condition and existing condition of No. V ore body, taking into account the actual mine production conditions, it carries on numerical simulation analysis by using FLAC3n software in -580 m level stope and proposes multiple mining programs. By analyzing the stress, deformation and damage of roadway surrounding rock and backfill in process of stope mining, the paper puts forward the best optimization program, with a view to guide similar engineering construction.
