摘　　要：在系统安全评价中,目前常采用事故树定性分析的3种主要方法:基本事件的结构重要度系数法,基本事件的割集重要度系数法,利用概率重要度性质求结构重要度法。通过对这3种方法在矿井安全评价中的应用进行分析、比较,提出采用基本事件的割集重要度系数法简单方便,并以煤电钻触电事故为例,介绍了其使用过程,建议在矿井评价中采纳。In the course of system safety assessment, there are three kinds of accounting methods about QFTA, including computing strucrural importance of basic event, computing probabilistic importance of basic event, utilizing probabilistic importance to calculate structural importance. In this paper the three means are analyzed and compared , computing prebabilistic importance of besic event is considered to be simple and convenient, and it＇ s using process is introduced by means of electrocuting accident about dectric coal drill. Finally the method is advised to be utilized in mine safety evaluating.
