摘　　要：介绍了在包头市某工程实施管道穿越黄河施工中,采用爆破法处理卡钻的经验。针对深水环境条件及钻杆内径小不宜采用集团装药的条件,确定采用"小直径爆破筒,钻杆内部装药"的爆破方案,阐述了爆破设计及施工注意事项。可供类似工程参考。In the construction of a project in Baotou which implemented pipeline crossing Yellow River, the experience of using blasting method in dealing with sticking was introduced. Aiming at the deep-water environmental condition and the requirement that small inner-diameter of the drill pipe should not use group charge, blasting scheme of small diameter hangalore, drill pipe internal charge was determined, and blasting design and construction caution were described. It could be referred for similar engineering.
