摘　　要：结合河北张河湾抽水蓄能电站的工程特点,确定了使用混装铵油炸药进行爆破开挖为最佳选择,并通过实践证明了所采用的逐孔微差爆破网路的可行性和优越性。根据现场混装铵油炸药爆破开挖所取得的施工经验,对在手风钻保护层中采用混装铵油炸药爆破进行了试验研究,效果良好,提高了钻爆作业效率,降低了钻爆成本。这一混装铵油炸药的应用实例,对类似工程有一定借鉴价值。Combining with the features of Hebei Zhanghewan Pumped Storage Power Station project, using of mixed ANFO determined for blasting excavation was the best choice, and the millisecond delay initiation network was feasible and superior proved by practives. According to the site experience of mixed ANFO blasting excovation, tests of mixed ANFO blasting in the pretective layers were carried by preumatic drills, and which got well effects of improving the efficiency and reducing the cost of drilling and blasting. This example of mixed ANFO explosive application has some reforences value for similar projects.
