摘    要：根据国内发生的尾矿库主要溃坝事故,运用事故树方法从自然灾害、坝体质量问题、人因管理缺陷等3个方面对尾矿库溃坝事故进行了研究,指出地震、库区山体滑坡、排水设施破坏、坝体失稳、人因管理缺陷是引发尾矿库溃坝事故的主要原因,提出了相应的事故预防措施,可为尾矿坝运行阶段的安全管理提供依据。

Abstract: Firstly,base on some past examples of tailings dam break in our country,the accidents are studied with fault tree analysis from 3 aspects,natural disaster,quality issues of dam body,shortcomings of human factors and management.Secondly,earthquake,landslide in reservoir region,failure of drainage structures,dam instability and shortcomings of human factors and management are identified as the primary factors to cause dam break.Finally,some accident prevention measures are proposed which would provide a basis for safety management of the tailings dam during their operation phase.
