摘　　要：介绍了在某水电站进行的混凝土面板堆石坝坝料开采爆破试验的情况。试验突破了仅根据岩石坚固性系数选取单位炸药消耗量的传统习惯，结合岩体裂隙与风化程度确定单位炸药消耗量，并采取分段装药、严格控制各段装药量和炮孔堵塞长度等措施，取得了良好的爆破效果，This paper introduces an experimental study on exploring stones by the blasting in benchesfor the rockfill dam in Zhushuqiao Hydropower Station,China. It gets a series of excellent resultsbecause of selecting the explosive factor not only by the rock firmness factor but also by theweathering state and the fracture density of the rock mass,taking the accurate broken charge andan enough samped stemming length.

关 键 词：梯段爆玻 单位炸药消耗量 堆石坝
