摘要
针对地下矿山高阶段大直径深孔采矿炮孔深、孔径大、单孔担负矿量大等特点以及集中凿岩、分段崩矿的工艺要求，就大孔径光面爆破在高阶段大直径深孔采矿中的应用参数选择以及光面爆破工艺进行了应用性探讨。
Smooth blasting technology is applied to reduce the destructive action of large diameter longhole blasting to the pillars and wall rock so that the results such as good stope stability, low ore loss and dilution are obtained The parameters and process of large diameter longhole smooth blasting technology are discussed in this paper
