| Abstract: | In view of the phenomenon of the secondary flying for deposit dust in the roadway.The author applies numerical simulation method to study secondary flying for dust,which analyses the relationship between the limit wind speed and the dust particle size in the state of secondary flying of dust.The research provides a reference for dedusting,so as to create a good working environment for miners. |
