摘　　要：通过对比分析电雷管起爆网路和非电导爆管雷管起爆网路的优缺点,认为拆除爆破中的大规模起爆网路宜采用非电导爆管网路。非电导爆管网路中,推荐方便快捷、安全可靠的纯"大把抓"网路和"大把抓"、四通复式网路,前者具有防水功能,后者网路层次分明。可靠度计算与工程实践均证明上述推荐的2种非电起爆网路,能够一次安全可靠的起爆成千上万发雷管,安全可靠性高。According to comparison of electric priming circuit and non-electric nonel tube system, the latter is suggested to be adopted in demolition blasting, especially in the ease of large detonators. The non-electric nonel tube system such as batch nodes only,or batch nodes ＆ 4-way nodes,is used generally,because they are convenient and efficient, and the former is immune to water, while the latter is concise. The reliability analysis and engineering prac- tices both show that if the two non-electric nonel tube system discussed above are used properly, thousands of detona- tors can be primed simultaneously.
