摘　　要：爆破震动是爆破的主要有害效应之一。为解决露天采场生产爆破对周围建筑物的影响,根据矿山的具体条件,采用孔间微差爆破技术在现场进行了试验。试验结果表明,露天采场采用孔间微差爆破技术能取得较好的减震效果。Vibration is one of the most damaging effects of blasting. To avoid the effect in open mining on nearby civilian houses, according to the specific condition of mines, a series of in - situ experiments were made with the technique of microsecond delay and hole - by - hole firing. The results show that this technique can be used to decrease the damage effects of blasting vibration effectively in open mines.
