魏家峁露天矿东一外排土场增高稳定性研究

Stability research on the eastern external dump after increasing height in Weijiamao Open-pit Mine

介绍了魏家峁露天矿排土场的概况,对软弱层的物理力学指标及流变特性采用试验的方法进行研究,确定出排弃物料的力学指标,最后利用FLCA3D软件建立模型,通过模拟分析确定出增高后排土场无滑坡危险。

This article introduces the general situation of dump in Weijiamao Open-pit Mine, and researches the physical and mechanical indexes and theological properties of the weak layer, determines the mechanical index of the discarded material. By usingFLCA3D software to establish the model, the article determines no landslide risk of＇ dump after increasing height by simulation analysis.
