摘　　要：为了掌握凤阳县某石英岩矿山边坡稳定性情况,提高边坡安全管理水平,通过现场调查露天采场实际作业情况和查阅地质资料,采用基于极限平衡原理的简化Bishop法对矿山现状靠帮边坡进行稳定性分析,确定边坡安全状况。结果表明:矿山现状边坡稳定性较好,没有发现滑坡、坍塌等边坡破坏现象,但南侧靠帮边坡后缘发现有拉张裂缝,在强降雨等特殊工况下边坡虽属安全稳定,未来生产过程中仍需不断加强边坡维护工作。In order to have a good understanding of the stability of a quartzite mine slope in Fengyang County and improve the level of slope safety management,the simplified Bishop method based on the principle of ultimate equilibrium was adopted to analyze the stability of the mine slope and determine its safety status through on-the-spot investigation of the operation of the open pit and consulting geological data.The results show that the current slope of the mine is stable,without the failure of landslide or slumping except that tensile cracks were found at the rear edge of the southern bank-near slope.Under special working conditions such as heavy rainfall,the slope is safe and stable,The maintenance of the slope still needs to be continuously strengthened in the future production process..
