摘　　要：为了论证并串联电爆网络的可靠性,根据电雷管电阻值的分布规律,利用数学方法计算出并联电阻期望值,以串联电路准爆条件为基础,推导出电容式发爆器并串联电爆网络的三个准爆条件。经验证,使用MFB型发爆器时,五种国产电雷管在并串联情况下均满足此准爆条件;同时经多次实践检验,并串联电爆网络可成功运用于实际爆破工程中,具有高可靠性和安全性。To prove the reliability of parallel-serial electro-explosion network, the study calculated the expected value of parallel resistance based on distribution rule of electric detonator＇s resistance value; it also deduced three firing conditions of capacitance-type initiator based on the serial circuit firing condition. When using the MFB initiator, 5 kinds of electric detonators made in China all satisfy the firing condition; meanwhile, after multiple practice tests, the result shows that the parallel-serial electro-explosion network can be used in the real blasting engineering with high reliability and safety.
