摘要
通过使用空气间隔器实现孔底(超深部分)不装药的爆破技术,达到降低孔内爆炸压力,减缓炸药作用时间。实现提高爆破质量,降低炸药单耗,从而证明利用空气间隔器实现底部空气柱爆破在海南铁矿的应用是成功的。
With the blast technique to leave hole end, i.e. super deep part, empty without explosive with air interval device, the explosion pressure in hole can be reduced, the explosive conducting time prolonged, blast quality raise and consumption lowered. It is proved to be successful in our mine.
