摘　　要：大直径深孔采矿法因为其高效率、低成本、安全性好在矿山得到了广泛的应用。介绍了我国地下采矿大直径深孔爆破技术的应用研究现状,剖析了主要问题及其危害。而后以铜绿山铜铁矿大直径深孔采矿方案为例,从凿岩工艺、装药结构与爆破参数三个方面,简述了其解决方案与主要优点。Large-diameter longhole mining method has been widely applied for its high efficiency,low cost and good security. This paper introduces the current status of domestic application and research of large-diameter longhole blasting technique employed in underground mining and discusses main problems and harms. Then the large-diameter longhole mining project which was employed in Tonglushan Copper-iron Mine is taken as an example. Finally, the solution and primary merits are expounded in terms of rock-drilling technology, charge structure and blasting parameters.
