摘　　要：依据安全评价的基本原理,在分析某小型露天非煤矿山边坡设计及其相关参数的基础上,对矿山边坡事故危险性进行了讨论.引入极限平衡定量安全评价方法,对该矿山开采台阶边坡和最终边坡角稳定性进行量化计算,得到在现有设计开采条件下,该矿山边坡的稳定性是安全的.同时计算结果和后期工程施工设计结果一致,符合非煤矿山开采安全规程的控制要求,证明了极限平衡法这一定量安全评价方法在小型露天非煤矿山安全评价中的适用性.根据分析计算结果,针对性的提出了预防小型露天矿山边坡事故的安全对策措施.According to the basic principles of the safety evaluation,and based on the analysis of slope design and its related parameters of a small open-air non-coal mine,slope accident risk of the mine is discussed.With the introduction of quantitative safety evaluation method of limit equilibrium,the slope of bench mining and the stability of final slope angle is calculated quantitatively,which proves that the stability of the mine slope is safe under the condition of the existing design exploitation.At the same time,the result and the future mining design are in the same construction,which accords with control requirements of the non-coal mine safety rules and proves the applicability of limit equilibrium in the safety evaluation of small-scale open-pit mine.According to the result of the analysis and calculation,safety countermeasures aiming at preventing slope accident of small-scale open-pit mine are put forward.
