| 摘 要： | 采场回采顺序及结构参数对提高采场回采安全性,降低回采损失、贫化率,提高回采效率有重要意义。利用FLAC3D数值分析软件,对不同结构参数采场稳定性进行数值模拟分析。通过对矿柱及围岩的应力、应变及破坏特征进行分析,得出不同采场结构参数条件下采场的应力、应变及破坏特征变化规律,最终确定合理的回采顺序及采场结构参数,提高采场回采安全性及回采效率。

| Abstract: | Stope mining sequences and structural parameters are important to improve mining safety,reduce mining losses and dilution rate,and increase the extraction efficiency.Stope stabilities with different structural parameters are analyzed by the numerical analysis software FLAC3D.By analyzing the stress,strain and failure characteristics of the rock pillars and wall rocks,the stress,strain and failure characteristics with different structural parameters are summarized.Reasonable stope mining sequences and structure parameters are drawn,and the stope mining safety and mining efficiency are also improved. |
