Abstract: It’s an economical way to use the presplit blasting to ensure the slope integrity in the process of building the reservoir of pumped storage power station. However, as perennial drought in Northwest, weathered rock and fracture zones in mountain, control of pre-split blasting is important. Taking Huhehaote pumped storage power station as an example, the paper introduced the scheme design, loading dose, initiation network, security measures, construction organization and effect of the presplit blasting. Further, blasting effect was analyzed, for reference.

摘要： 抽水蓄能电站建设修建水库过程中，采用预裂爆破以保证边坡的完整是一种非常经济的方法。但是，由于西北地区常年干旱少雨，岩石风化严重，山体含有大量的破碎带，所以预裂爆破的控制显得尤为重要。以呼和浩特抽水蓄能电站为例，介绍强风化地质条件下预裂爆破的方案设计、装药量、起爆网路、安全防护措施、施工组织以及爆破效果，并对爆破效果进行分析，为同类工程的实施提供参考。
