摘　　要：给出了影响露天煤矿边坡危险度因素集,利用可拓学理论建立了露天煤矿边坡危险度评价数学模型,各因素权重采用层次分析法确定。研究表明,层次分析法与可拓学的结合降低了危险度评价中人为因素的影响。以安太堡露天煤矿为背景,采用上述模型对其边坡进行了危险度评价,所得结论表明危险度较高,必须采取一定的防护措施。Set of factors which influence the stability of open-pit slope is given at first. The risk degree evaluation mathematical model of open-pit slope is established with extension theory and the weights of every factor are determined through analytic hierarchy process. Studies show that combination of analytic hierarchy process and the extension theory can reduce the influence of human factors in risk degree assessment. Then the model is used to evaluate the risk degree of Ann too open-pit slope. The results reveal that the risk degree is high, so some protective measures must be taken.
