介绍了中深孔爆破在奥运会飞碟靶场石方开挖中的应用,在复杂环境下,采用孔外多段毫秒延时、低单耗、加长填塞等技术措施,较好地控制爆破振动及飞石的危害.在不良地质条件下采用预裂爆破技术,优化预裂爆破参数,保证了边坡的平整.对实施经验进行了总结,可为同类条件下的爆破提供参考.

The application of the technique of the excavation by long-hole type blasting in the Olympic Games flying-saucer stadium was introduced in the article. In the complicated surroundings, some techniques were adopted such as out-hole millisecond delay blasting, underload, the longer length of stemming to control the danger of blasting vibration and fly rock, at the same time, in view of the complex geological condition, presplitting blasting was adopted so that blasting parameters were optimized to make the side slope integrated. The paper summarized and provided some experiences of construction.
