深孔松动微差控爆技术在岩石开挖工程中的应用

The Application of Short Delay Controlled Blasting Technology for Deep Hole Loose in Rock Excavation

本文简要介绍了深孔松动微差控制爆破技术。结合百龙滩水电站下闸首基础石方开挖工程,详细介绍了该技术的爆破参数计算。工程爆破效果证明该爆破技术是非常适合岩石开挖工程的一门新技术,值得广泛推广。

Short delay controlled blasting technology for deep hole loose is presented in this paper. The blasting parameter calculation of the technology is analyzed with the discussion on the rock excavation of the first foundation in next floodgate of Bailongtan hydroelectric power station. It is showed that the technology is new and suitable for rock excavations, which is worthy of wide use.
