摘　　要：为了提升煤炭资源回收利用率,以新疆天池能源南露天煤矿南端帮为研究背景,通过分析该露天煤矿边坡工程技术参数,对提升煤炭资源回收利用率进行了研究;通过采用极限平衡法和强度折减法分别对南露天矿南端帮不同时期的二维剖面模型进行稳定性分析。结果表明:2022—2023年边坡稳定系数较低,基于边坡稳定性计算结果,通过调整南端帮边坡设计参数,边坡稳定系数提升明显。In order to explore the technical means to improve the recovery and utilization rate of coal resources,taking the southern end slope of an open-pit coal mine in Xinjiang as the research background,the article analyzes the technical parameters of the slope engineering of the open-pit coal mine,and studies the improvement of the recovery and utilization rate of coal resources.We use the limit equilibrium method and strength reduction method to analyze the stability of the two-dimensional profile model of the southern end slope of South Open-pit Mine in different periods.The results show that the slope stability coefficient is low in 2022-2023.Based on the calculation results of slope stability,the slope stability coefficient is obviously improved by adjusting the design parameters of the southern slope.
