摘要
根据电爆网路盲炮产生的原因,构建了盲炮事故树,通过对盲炮事故树结构重要度分析,求出了盲炮事故树的最小割集,并对各基本事件重要度进行了排序,从而找出了盲炮产生的主要原因。最后从安全系统工程的角度对电爆网路盲炮预防措施进行了系统的梳理和分析,提出了避免产生盲炮的主要对策,对电爆网路中盲炮的预防具有较好的指导意义。
According to causes of the misfire in the blasting electric circuit,fault tree analysis （FTA） of misfire was constructed. On that basis, each elementary event was ranked orderly, and then, the minimum cut sets were obtained through analyzing the structure importance of the FTA. Consequently, the main reasons attributed to misfire were found out. Finally, preventive measures of misfire were sorted and ana- lyzed systematically from the perspective of safety systems engineering, and a series of fundamental coun- termeasure were put forward to prevent the emerging of misfire, which could have some guiding signifi- cance for taking precautions against misfire in the blasting electric circuit.
