光面爆破技术研究及其在隧道掘进中的应用

在简述光面爆破机理的基础上 ,讨论了在只能把直径 32mm的普通硝铵药卷用于光面爆破的条件下的参数计算方法。通过一个工程实例 ,介绍了爆破参数计算方法的应用。文中对如何用好光面爆破技术阐述了作者的认识和体会 ,并提出了进行“水压光面爆破”试验的建议。

STUDY ON SMOOTH BLASTING TECHNOLOGY AND ITS APPLICATION IN TUNNEL EXCAVATION

In this paper, the calculation of blasting parameters under the condition of only using general ammonium nitrate explosive cartridges with a diameter of 32mm for smooth blasting was discussed on the basis of briefly stating the mechanism of smooth blasting. Through an engineering example, the application of the calculating method of blasting parameters was introduced. In addition, author's understanding and experience of how to well use smooth blasting technology were expounded and a proposal for test of water pressure smooth blasting was put forward.
