预留岩墙精准深孔控制爆破技术研究

Study on the precise control of deep hole blasting technology in preserved dike

为减少主爆区施工时难度和对周围环境的危险性,提出了采用预留岩墙爆破技术施工,通过分析预留岩墙处理技术的利弊、预留岩墙的关键性爆破参数,指出预留岩墙采用精准深孔控制爆破技术,爆破过程安全快捷,可为类似工程提供科学依据。

In order to reduce the difficulty of the main blasting area and the dangerous of the surrounding construction. This article has adopted the blasting technique for preserved dike, through the analysis of advantages and disadvantages for preserved dike and the key blasting parame- ters, the preserved dike with precision deep hole controlled blasting technology is proposed, the blasting process quick and safe. The experiences of the project provided some references for the future similar blasting projects.
