摘要：

The paper presents the results of a study of the morphological composition of coal dust fractions of the coal grade 2J of the Triple sh. Vorkutinskaya formation of the Pechora coal basin. Studies of coal mine dust particles with a dispersion of less than 0.1 mm were performed using the LEICA DM 4000 optical microscope and the IMAGE SCOPE Software. the Studies revealed certain class-forms of particles. It was found that the shape of the parallelepiped best describes the coal dust particles presented in the samples. This class-form is embedded in a mathematical model that allows you to predict the distribution of explosion-and fire-hazardous coal mine dust in mining workings. Implementation of the computational model of the study was carried out using a specialized complex ANSYS FLUENT.
