摘要： 某矿山企业浮选厂边缘经挖山平整形成一高边坡，在初期加固治理后，因多种因素作用又重新发生失稳破坏，有加速变形破坏可能，给矿山安全生产带来威胁。在稳定性分析基础上，研究了地层分布特征、降雨等对边坡的影响，揭示出边坡的滑移破坏机理；在此基础上对提出的边坡整治方案进行验算，为边坡的治理提供了有力依据。

Abstract: A manmade high slope at the edge of a floatation ore processing plant was formed by the mining excavation. The slope was identified having accelerated deformations and having safety hazard to the mining operation. This paper studied the impact of subsurface soil condition and precipitation on the slope stability. The mitigation measures are proposed based on the stability analyses.
