砂石矿露天开采边坡稳定性分析研究

Open-pit Mining Slope Stability Analysis of a Gravel Mine

随着露天采场的不断增多,开采难度日益增大。我国的大中型露天矿一般设计终了开采高度为300~500 m,有的甚至可达700 m。在对这些砂石矿开采期间,为保障开采过程的安全性,需要在前期探讨其设计边坡的稳定性。文章针对某采石场露天开采边坡的岩体工程、区域地质环境条件等,根据现场调查与资料分析提出其边坡失稳破坏的重要模式,并根据对该矿区岩土工程的内容分析,探讨其边坡稳定性,以保障开采过程的安全。

With growing open pits,mining becomes harder.The final design mining height of large and midsized open-pit mines in China are usually 300~500 m,for some mines can be 700 m.To ensure safety mining,analysis of slope stability is necessary.The paper explores the slope stability of an open-pit quarry based on its geotechnical engineering,regional geological conditions and other on-site investigation data to ensure a safety excavation.
