Slurrying and Dust Removal Technology of Spraying Machine in Driving Face of Huayang No.1 Coal Mine
In order to solve the problem of the large amount of dust produced during the shotcrete operation of the anchor net spraying working face,the dust control technology of the spraying machine was studied by theoretical analysis,experimental research and industrial practice.The dust during the blanking period was controlled by the scraper conveyor and the dust during the pulping period was controlled by the dust control hood,and the optimal suction parameters were determined by experiments.The factors affecting the dust removal effect of the wet dust collector were analyzed,and the best parameters such as filter screen aperture and spray gas-water ratio were obtained.The dust control system designed for the spraying machine was applied to the 81214 driving face of Huayang No.1 Coal Mine.The overall dust removal efficiency was above 96%,and the application effect was good.
