摘　　要：为保证露天采场边坡稳定,解决安全风险评估问题,降低风险,根据常见的边坡稳定性影响因素,实地考察和查阅文献资料,构建了以权—未确知测度危险性评价模型,并结合矿山实际特点,并将此模型应用在刚果金某铜钴矿露天边坡边坡稳定性评价中,结果与现场实际贴合度较高,取得了良好的效果。研究结果表明,该模型计算过程简单,结果合理可靠,为有效进行露天采场复合型边坡的安全风险评估提供了不同思路.In order to ensure the slope stability of the open-pit stope,solve the problem of safety risk assessment and reduce the risk,according to the common influencing factors of slope stability,field investigation and literature review,a risk evaluation model based on weight unascertained measurement is constructed.Combined with the actual characteristics of the mine,this model is applied to the stability evaluation of the exposed slope of a copper cobalt mine in the Democratic Republic of the Congo,and the results are in good agreement with the actual situation on site,Good results have been achieved.The results show that the calculation process of the model is simple,the results are reasonable and reliable,and provide different ideas for the effective safety risk assessment of compound slope in open pit.
