Abstract: An overview of Russian and foreign methods and approaches to control carbon-containing dust in the atmospheric air in the operation area of coal mining and processing enterprises is presented in this paper. The main composition of suspended substances (coal dust) emitted in the atmosphere in the processes of coal mining and processing includes an inorganic part, represented by the main rock-forming oxides, toxic elements, mineral particles PM2,5 and PM10, also organic substances, which include soot (carbon), organic matter of coal, benz(a)pyrene and other PAHs. The toxic elements content in coal can vary significantly within even a single coal basin; so the study of the elemental coal composition in the Kuznetsk coal basin and their processing products must be carried out in order to develop new geotechnologies for integrated development of coal deposits and planning monitoring of environmental objects in the operation area of coal mining and processing enterprises. It is necessary to measure the particle size distribution and determine the proportion of the most dangerous classes for estimating the toxicity of fine coal systems. The laser diffraction method is the most informative and reliable method for these purposes. The data of the composition and properties of coal dust of Kuzbass enterprises were obtained on the basis of studies of coal, overburden and host rock and contain the results of toxic elements, PAHs, and granulometric composition determination. The development of scientific bases and practical methods for polyaromatic hydrocarbons extraction from Kuzbass coal and the study of the distribution of these carcinogenic compounds representatives in the region is actual and necessary for predicting the carcinogenic hazard in coal mining, transportation and processing.
