The Influence of Dust Dispersion on the Law of Blasting Dust Emission Based on Microscope

Dust is everywhere in everyday life. The dust dissipation condition will affect the development of dust prevention and dust suppression measures, dust control equipment selection and construction arrangements. Dust dispersion can reflect the distribution and harmfulness of dust, which has important research significance. The use of microscopy for the determination of dust dispersion has long been regarded as the perfect method for dust dispersion analysis. Based on the dust dispersion and the microscope as a tool, the influence of dust dispersion on the blasting dust dissipation law was analyzed. In this paper, the dispersion of different particle sizes from different working faces, the dispersion of dust with different particle sizes, the different test sites, and the proportion of different particle size dispersions were studied. From this we found that the larger the particle size, the smaller the proportion of its dispersion. At the same time, we found that the most harmful to the human body is dust with a particle size of less than 5 mu m, because they escape the most in the air.
