The storage of bulk materials at industrial sites leads to significant dust pollution in work areas. An important task is to study the patterns of dust formation and air pollution under various weather conditions at industrial sites. The article presents the results of experimental studies to determine the intensity of dust emissions from a coal site. The study was conducted for different air flow speeds. An empirical model was obtained that makes it possible to estimate the intensity of dust formation at industrial sites. The pattern of change in coal dust concentration at different distances from the coal site was determined. Two numerical models were developed to predict dust pollution of the air at industrial sites. The models are based on the use of finite difference splitting schemes to integrate a multidimensional mass transfer equation.
