摘要

通过对光面爆破技术在节理化岩体中实施爆破方案的不足之处的分析，引入了双向聚能拉伸爆破技术，并简要分析和介绍了该技术的基本技术原理和优点以及两种爆破设计方案，同时对该技术在两个大型洞室工程中的高岩台应用情况进行了分析和介绍，最后就该技术的今后的研究方向提出了一些设想。

Abstract

Based on analyzing challenging problems in the jointed rock mass confronting the smooth blasting technology

a new blasting technology

a two-direction energy-gathering blasting technology

is introduced for the jointed rock mass. Next the basic technical principles and advantages of the technology has been dealt with in detail

so have the two design schemes. Finally

two application cases are put forward to demonstrate the application prospect of the technology.
