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。采用该技术可提高施工速度,降低成本,可在井巷工程中等及其以上稳定岩层施工中推广应用。
The brocken rock mechanism of the middle deep hole smooth blast is introduced in detail. And combined with practical exanaple expounds the technical demands of the middle deep hole smooth blast. By this technology can improve the construction speed, reduce cost, and may spread in the middle or over middle shaft construction with stable rock stratum.
