近日，我国目前最大规模水下深孔爆破在吉林引松（花江）入长（春）工程施工中获得成功。这项工程是由铁道部十三局和铁道建筑设计院共同施工的。这次爆破在国内首次将塑料导爆管非电起爆系统应用于水下大规模深孔爆破，通过采用孔外等间隔微差起爆技术、宽间隔爆破技术和交叉 Recently, the largest underwater deep-hole blasting in our country succeeded in the construction of the Jinsong (Spring) Project of Jilin Jinsong (Huajiang). This project was jointly constructed by the 13th Bureau of the Ministry of Railways and the Railway Construction Design Institute. The blasting in the country for the first time the plastic detonating tube non-electric detonating system used in underwater large-scale deep-hole blasting, through the use of holes outside the interval differential detonation technology, wide-interval blasting technology and cross
