摘要
该文以工程实例为背景,介绍了精细爆破的概念以及在水利水电工程岩石边坡爆破开挖中的应用,重点介绍了基于对保留岩体保护的精细爆破参数的设计方法。边坡岩体开挖满足质量标准、保留边坡岩体完整稳定、预裂爆破残留炮孔痕迹保存率85%以上,取得了良好的施工效果。
In this paper, the concept of precision blasting and its application in blasting excavation of rock bank slope in waterconservancy and hydropower engineering are introduced. The design method of precision blasting parameters based on preservation ofpreserved rock mass is introduced emphatically. Slope rock excavation can meet quality standards, and retain the integrity of rockslope stability. And presplit blasting residual traces of the hole is more than 85%. Good construction results are achieved.
