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,可供同类型矿山推广应用。
Based on excavating waste raises to goaf in rock with well-developed joint deep hole blasting shaft high raise is illustrated by using the burned-cut blasting method. This way is applied extensively in the whole mine with safety, efficiency and and crack partly, a way of method and crate blasting reliability.
