摘　　要：分析了某露天矿深孔爆破爆前、爆中、爆后粉尘的来源,通过若干次试验,采用爆前预湿、水间隔装药、碎石充填、优化孔网等方法,很好地抑制了某石灰石矿深孔爆破产生的扬尘,满足了该矿西南方向某新建大型机场通航安全对降尘的要求。It analyzed the cause and source of deep hole dust in before,during and after blasting.Through some tests,it found that applied several methods,such as pre-wetting blasting area,water deck charge,stemming by crushed stone,parameters optimization and so on,the dust of deep-hole blasting in one limestone quarry was effectively constrained,and local government requirements for the new big international airport navigation safety was met.
