摘要
大河口水电站将深孔微差爆破运用于导流隧洞开挖。通过分析、对比验算和观测结果，取得了适宜的爆破方式、钻爆参数和爆破规模，对加快施工进度起了重要作用，并获得了显著的经济效益和社会效益。
Micro-difference blasting in deep hole is carried out in excavation of diversion tunnel at Dahekou hydropower station. By analyzing and comparing checking computation and measurements,adquate blasting method,parameters for drilling and blasting and blasting range are obtained. This plays a imPOrtant role to speed up construction progress and gains obvious economic and social benefit.
