建立了电起爆器可靠性模型；进行了故障模式、影响及危害度分析；采用冗余、优化及环境防护等可靠性设计方法对电起爆器进行了可靠性设计；利用GJB376、GJB377对电起爆器主要性能的可靠度作了评估．
The reliability model of the electric detonator was established. The failure mode, influence and hazard degree analysis were carried out. The reliability design of the detonator was carried out by reliability design methods such as redundancy, optimization and environmental protection. The detonators were detonated by GJB376 and GJB377 The reliability of the main performance of the device was evaluated.
