  • According to the principle of deriving mine dust distribution from the Rosen-Rammler distribution function,dust particle size distribution data at four places on the 4339 working face in Wangzhuang Coal Mine were regression-analyzed so as to get the dust particle size distribution law.The results show that in the area of 5 m away from the working face in the intake airway,the percentages of mine dust of less than 5 μm,5 to 10 μm and larger than 10 μm in particle size are 14.8%,32.5% and 52.7%,respectively,with a concentrated distribution of 5 to 20 μm.The size of mine dust concentrates in the range of 5 to 10 μm for the transfer point,in the range of 5 to 10 μm for the 50# support of the working face,and in the range of 5 to 20 μm for the area of 20 m away from the working face in the outlet lane.Some corresponding dust-proof suggestions were finally put forward on the basis of the characteristic of mine dust distribution in different places.
