露天煤矿非工作帮顺层边坡致滑机理及稳定性分析

Mechanism and Stability Analysis of Non-working Side Bedding Slope in Open-pit Coal Mine

对新疆某露天煤矿地质特征进行分析,采用控制变量法,改变平盘宽度及边坡角,分析非工作帮顺层边坡的稳定性,得出该矿顺倾边坡的安全稳定系数,根据计算结果,提出合理的开采顺序,通过加强维护检查、加固抗滑工程等措施,做好边坡防护。

The study analyzes the geological characteristics of an open-pit coal mine in Xinjiang,and the stability of the bedding slope of the non-working slope by using the method of controlling variables and changing the width of the flat plate and the slope angle;and obtains the safety and stability coefficient of the bedding slope of the mine.According to the calculation results,the slope protection measures such as reasonable mining sequence,strengthening maintenance and inspection,and anti-slide engineering reinforcement are proposed.
