系统地研究了超低能导爆索的传爆原理，结合工程实际需要，拓宽应用范围的研究，为深孔土岩爆破的反向起爆提出一种新型的，安全、可靠、高效的起爆网络。

In this paper, the detonation transmission rules of the super low energy detonating cord was studied. Combining with engineering problems,a new priming net which can be used in the reverse priming in deep rock shot holes is proposed. It's reliable, efficient and safe.
