有限元数值分析在铜绿山矿残柱回采方法选择中的应用

Application of Finite Elementary Numerical Analysis in the Selection of Stoping Methods for Residual Pillars in Tonglushan Mine

为回采铜绿山矿的残留间柱 ,在现场岩石力学调查的基础上 ,对用不同的采矿法回采残留间柱的采场稳定性进行了有限元数值分析 ,从而选择了适宜的采矿方法 ,确定了合理的采场结构参数 ,并达到了预期的效果。

For recovery of residual interstall pillars in Tonglushan Mine, field rock mechanics was investigated. Based on the results, stope stability for different stoping methods for recovering these pillars was studied using finite elementary numerical analysis. As a result, the most appropriate mining method with reasonable stope structure parameters was adopted, having achieved desired results.
