摘要
岩塞爆破是开挖隧洞进水口的一种爆破技术，所用炸药应具有良好的抗水性能，通常采用胶质炸药和水胶炸药。贵州印江岩口抢险工程中首次将乳化炸药用于岩塞爆破获得成功，达到了爆通、成型、安全的基本技术要求，为抢险工程做出了很大贡献。
The rock-ping blasting is a kind of blasting technique for the excavation of tunnel intake. Slurry explosive and gelatin dynamite are usually used in the rock-plug blasting because they are the water-resistant explosives. In Yinjiang Yankou wrecking project in Guizhou Province, the emulsion explosive was first successfully used in the rock-plug blasting work. And this has met the basic technical demand of blasting completion, shaping and safety. It is a great contribution to the wrecking project.
