| 摘 要： | 利用FLAC程序 ,对鞍山矿业公司眼前山铁矿采场南帮的两种开采方案分别进行了模拟研究。以模型中出现的破坏区域和破坏程度来评价高边坡的稳定性 ,从而评价深部两种开采方案可能形成的破坏情况。计算结果表明原有设计方案深部开采会导致局部破坏 ,调整方案有效地改善了深部边坡状况

| Abstract: | The authors use FLAC to carry out simulation analysis on two mining options in southern slope of Yanqianshan Iron Ore Mine of Anshan Mining Company.The stability of high rock slope and the possible failure caused by two deep mining options are assessed based on the failure region and failure extent occurring in the model.The calculation results show that the original plan,i e.,deep mining will result in partial failure.The adjusted plan improves effectively the status of deep slope. |
