摘　　要：为评价南芬露天铁矿的安全风险,根据南芬露天铁矿安全现状,从安全管理制度、边坡安全管理、采场安全管理、边坡防治这4个方面构建南芬露天矿安全评价指标体系,并采用突变理论对南芬露天矿的安全风险进行分析,结合实际,对南芬露天矿进行安全评价。结果表明,南芬露天铁矿突变隶属值为0.891,现场安全风险较好,但安全管理制度的隶属度值较低,在以后的工作中应着重安全管理制度的完善、健全及落实,避免因没有及时处理而出现相应事故。In order to evaluate the safety risk of Nanfen open-pit iron mine,according to current security status of this mine,the safety evaluation index system was established through four aspects of safety management system,slope safety management,stope safety management and slope control.Catastrophe theory was adopted to analyze safety risks of Nanfen open-pit mine.Combing with mining conditions,safety evaluation of Nanfen open-pit mine was conducted.The results showed that catastrophe membership degree value of Nanfen open-pit mine was 0.891.The site security risk was low and the membership degree value of the safety management system was low.In future work,emphasis should be placed on strengthening the safety management system to avoid corresponding accidents due to the failure of timely handling.
