| Abstract: | 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. |
