摘要: 为进一步探讨筑埂沉坝法的应用效果,分析了筑埂沉坝法的基本概念,以某矿山为例,采用MIDAS有限元分析软件的SRM和SAM两个模块分析了膏体尾矿持续排放对尾矿坝埂稳定性的影响。结果表明:随着尾矿不断地向库内排放,尾矿坝埂的稳定性整体呈降低趋势,但不明显,说明膏体尾矿持续排放对坝埂稳定性的影响较小。

Abstract: In order to analyze the application effects of sinking dam method by building dike,the basic concepts of the method is analyzed,taking a mine as the study example,the SRM and SAM modules of finite element analysis software MIDAS is adopted to analyze the influence of Continuous discharge of past tailings to the tailings dam stability.The results show that with the discharging of past tailings,the stability of tailings dam is decreased,but the decreasing trend is not significant,which indicated that the influence of continuous discharge of paste tailings to the stability of tailings dam is small.

Key words: Tailings discharge, Sinking dam method by building dike, Paste tailings, Stability of dam dike
