某矿高溜井深孔爆破成井技术探讨

    DISCUSSION ON HIGH RAISE TECHNOLOGY THROUGH DEEP HOLE BLASTING

    • 摘要: 针对某铁矿岩体局部节理裂隙发育,需掘进通向采空区的废石溜井,文章介绍了利用掏槽法和漏斗法联合深孔分层爆破形成高溜井的技术,该技术安全高效可靠,并全矿推广应用。

       

      Abstract: Based on excavating waste raises to goaf in rock with well-developed joint and crack partly,a way of shafting high raise is illustrated by deep hole blasting which uses burned-cut blasting method and crate blasting method.This way is applied extensively in the whole mine with safety,efficiency,and reliability.
