It shows that the network, affected by stream of water, superposes each other leading to the jet of detonator energy cavity and metal fragments which can break the nonel-tube without transmitting detonation yet, so as to make the detonation transmission in some local network break off and bring about misfire.

结果表明，受紊乱水流影响，导爆管网络相互叠加，比较凌乱，致使传爆雷管产生的聚能射流和碎片容易将尚未传爆的导爆管切断或打破，而使局部网路爆轰传递中断，造成拒爆现象的发生。

5The blasting vibration signals are analyzed by time-energy analysis. Identify the time of detonator priming and ascertain reasonable subordinate interval in millisecond delay blasting to decrease blasting vibration and control the damage of blasting. In this paper, wavelet analysis is used to de-noise the blasting vibration signals.

According to the experiment results,the author analyses the combustion propagation mechanism of detonator delay composition and believes that the combustion in the lead tube is impulsive combustion,which is the key factor of influencing the delay precision of the detonator;secondarily,the effect of the igniting power terminal is also very obvious.

本文实验测试了硼系延期药和硅系延期药燃烧传播过程，根据实验结果分析了延期药燃烧传播机理，认为延期药在铅管内的燃烧是脉动燃烧，是影响雷管延期精度的主要因素，其次点火药头的影响作用也十分明显。

The detonating cord and millisecond delay detonating tube with non-electric detonator priming system is used in our mine 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。
