井下大爆破常规起爆网路利弊论

Discussion on the Advantage and Shortcoming of Conventional Detonation Network for Underground Big Demolition

我司井下大爆破使用的是非电雷管、导爆索、导爆管微差复式起爆系统,但在现场操作中,由于对两种起爆器材的认识缺陷和偏见,在系统网路联结工作上存在不足因素,爆破结果表现出起爆器材不彻底起爆的现象。本文结合实际存在问题和不足,从两种起爆器材的原理出发,对系统网路联结工作中导爆索起爆法联结技术进行了利弊分析,杜绝了爆破中类似拒爆现象的再度发生。

The detonating cord and millisecond delay detonating tube with non-electric detonator priming system is used in our mine for underground big demolition. But in practical operation, due to the misunderstanding and prejudice to the two kinds of detonation equipment, there were some deficiencies on detonating network connection leading to incompletion detonating of the detonation equipment. Based on the principle of the two kinds of detonating equipment and the actual existing problems and deficieneie, the advantages and shortcomings of the technology for detonating cord connecting have been analyzed so as to avoid the occurrence of similar un-exploding phenomenon once again.
