摘要
详细介绍中深孔光面爆破破岩机理,结合工程实例论述了采用中深孔爆破的技术要求,中深孔光面爆破能提高施工速度,降低成本,在今后井巷工程中等以上稳定岩层施工中可推广应用。
The mechanism of middle deep hole smooth blasting are introduced, the technic request are discussed combining engineer example. Middle deep hole smooth blasting can increas construction speed and crease cost and can be extend and applied in the construction.
