摘要(Abstract)：

在张双铁路扩堑施工中,环境非常复杂,采用深孔爆破技术实现了一次爆破长达376m的路堑。通过采用逐孔延时起爆技术、优化爆破参数,很好地控制了爆破振动及爆破飞石的危害,取得了满意的爆破效果。文中介绍了孔外接力逐孔延时起爆网路,并总结了网路连接的要点,可为复杂环境下大规模石方快速爆破开挖提供参考。
The excavation of a ditch of 376m was fulfilled by only one single blasting with deep-hole in very complicated surroundings.The blasting was under well control of the danger of blasting vibration and fly rock,and saw a good effect by adopting techniques like hole-by-hole millisecond delay blasting technology and optimizing blasting parameters.The paper described the hole-by-hole blasting network and summarized the key points of network connecting,provided some experience for large-scale blasting in complicated surroundings.
