摘　　要：非电起爆系统在爆破工程中广泛应用，工业雷管如何安全、可靠起爆导爆管至关重要。本文开展了8号工业雷管起爆导爆管能力的模拟实验，分别对雷管正、反向起爆导爆管情形，不同捆扎约束力情况下导爆管引爆概率进行了研究，并对雷管起爆导爆管的可靠距离和不破坏临近导爆管的安全距离进行了研究。实验结果表明：（1）雷管正、反向起爆导爆管对起爆概率影响不大，但正向起爆存在金属射流或破片切断导爆管的可能；（2）导爆管的捆扎约束力越大，有效起爆导爆管数量越多，起爆概率越大；（3）雷管起爆导爆管的可靠距离≤1cm，不破坏临近导爆管的安全距离≥9cm。本文的实验结果与分析对工程爆破中非电起爆网络起爆可靠性、安全性分析等方面具有一定的参考价值。Non-electrical initiation system has been widely applied in blasting projects. So how to keep the safety and reliability of industrial detonators initiating the nonel tubes becomes very important. The article carried out the simulation experiment of the nonel tubes initiated by industrial detonators of series 8. The experiment investigated the initiating probability under the condition of the front and back shooting methods and under the condition of different enlacing forces. Also, the reliability distance of initiating the nonel tubes and the safety distance of not destroying the nonel tubes were put forward. The experimental results showed that：（1） the initiating probability revealed a smal difference when applying the front or back shooting methods. But the front shooting method may exit the thing that the metal jet and detonator lfyer cut off the nonel tubes;（2） the bigger enlacing force of the nonel tubes was, the bigger number of effective initiating nonel tubes was, that is to say, the initiating probability is higher;（3） the reliability distance of the detonators initiated the nonel tubes was less than 1cm, and the safety distance of the detonators not destroying the nonel tubes was higher than 9cm. The experimental results and analyses in this article can be regarded as a reference for analyzing the safety and reliability of non-electrical initiation system.
