摘　　要：采用安全系统工程方法,以陕西省某大理石矿为例,对非金属矿山爆破事故进行了事故树分析,并绘制出爆破事故树分析图,直观地表现了各可能导致顶上事件发生的基本事件及其逻辑关系,通过对FTA的定性分析,得出了最小割集和结构重要度,并提出了相应的安全对策。Taking a marble mine mining project in Shanxi province for example, this paper uses the safety system engineering method to analyze the nonmetal mines blasting accident with fault - tree. It also protracts the fanlt - tree of mining person electric shock accident which shows in an intuitionistie way all the possible basal incidents leading to the top incident and their logical relation. With the qualitative analysis of FIA, it obtains the minimal cut set and structure importance which indicate the possible approaches to avoid the accident. As the same time, this passage presents some prevention countermeasures accordingly.

关 键 词：事故树分析 爆破事故 结构重要度
