摘要
隧道掘进传统周边孔装药结构,采用导爆索加分段装药结构形式,介绍了一种新的爆破技术———周边孔空气间隔装药光面爆破技术。实际应用表明,该技术简单实用,既保证了光面爆破的效果,又极大地降低爆破施工的成本,带来的经济效益非常地可观,有极大地推广应用价值。
A new blast technology, air-deck charge using peremeter hole smooth blasting, has been introduced in this paper. Through using in practical project, this feasible technology can not only ensure the effect of smooth blasting but also greatly lower the cost of implementation.
