国内地下工程施工中对直眼掏槽爆破技术的研究和使用从五十年代末开始至今已有几十年的历史了,应该说这门技术是比较成熟的。但是施工中仍不时出现爆破效果不稳定的情况,究其原因有两条。一是由于施工时未满足钻爆参数设计的要求:二是因为该技术在理论研究上尚不完善。本文的目的是就该问题提出几点粗浅看法,供有关人员在设计和施工时参考。
The research and use of straight-eye cut blasting technology in domestic underground construction has been several decades from the late 1950s to the present. It should be said that this technology is relatively mature. However, the blasting effect is still unstable from time to time in construction. There are two reasons for this. First, due to the construction of the drilling and blasting parameters not meet the design requirements: Second, because the technology in the theoretical study is not perfect. The purpose of this article is to provide a few rough ideas on the issue for reference by relevant personnel in the design and construction.
