摘要(Abstract):

以百龙滩水电站下闸首基础石方开挖工程为例,介绍了深孔松动微差控制爆破技术的爆破参数计算,起爆间隔时间的选取,爆破震动的分析。该工程的爆破效果有力地证明了深孔松动微差控制爆破技术是非常适合岩石开挖工程的一门新技术,值得推广。
By taking the rock excavation of lower floodgate head foundation at Bailongtan hydraulic power station as an example,introduced the blasting parameter calculation,the selection of igniting interval time,and the analysis of blasting vibration regarding the project.The blasting effect of this project prove that long hole loose millisecond controlled blasting is a new technology extraordinarily suitable for rock excavation,and worth to be widely spread.
