摘　　要：预裂爆破的钻孔精度是预裂爆破的前提,它仍是工程上应严格要求和控制的重要因素。龙首水电站左右岸开挖爆破采用仪器监测,结合生产进行了一系列实验。主要介绍了现场预裂爆破试验的方法和措施,结合生产,研究分析了预裂爆破效果及影响,为爆破的设计和施工提供技术参数,可作为同类工程的参考。Drill precision is premise of the pre-splitting blasting, it is strict requirement and controlled key factor in the engineering. The Longshou hydropower station around land excavation adoption to instrument monitoring, and combined with production made a series of experiment. The simulative field pre-splitting blasting experiment, the pre-splitting blasting effect was studied, some parameters and bases are offered for design and construction of the pre-splitting blasting in this disquisition and the practice could be used for reference for similar project.
