采用非电塑料导爆管、孔外延时接力起爆网络实现的深孔微差抛掷爆破技术,将岩滩水电站上游碾压混凝土围堰~#18坝段前缺口一次爆除,取得了良好的爆破效果。
By deep hole millisecond pinpoint blasting with Nonel detonators reley initiation network, the demolition of a notch in the upstream RCC cofferdam in front of the 18th monolith of Yantan Hy droelectric Project attained success on 19 march, 1990, and it obtained a desired result.
