摘　　要：本文在对抚顺西露天矿北帮E1 0 0 0边坡变形及水压动态监测资料分析的基础上 ,建立了双层渗流分析计算模型 ,依据流量平衡原理和有限元数值方法 ,进行了边坡降雨入渗量、冲积层汇水量、疏干井及放水孔涌水量计算和动态模拟 ,提出了有实际意义的疏干排水方案。实践表明 ,效果良好。This paper,on the basis of an analysis of the variant and water pressure trends monitoring record data of E1000 side slope of the Fushun Western Open pit Coal Mine,establishes the two layers seepage flow analysing and computing model;in the light of the flow balancing principle and FEM computer simulation,makes an analogue calculation and dynamic simulation of such values as penetration of rain fall into the side slope,the sink water volume of the alluvial deposit,the flow of water in the drainage well and drain holes;and puts forward a drainage and pressure reduction scheme of real significance.Practice indicates the effect is favorable.
