The article presents the results of the grain-size and substance analyses of air suspensions at coal production objects. The atmospheric pollution is studied at all stages, from actual mining (Karakan coal cluster, Kuzbass) to loading (coal terminal, Vostochny port, Primorski Krai) to combustion (Heat power plant 2, Vladivostok). It is shown that within the same process flow, air microparticles have similar content and size. The quantity of toxic micro-size air particles gradually lowers on the way from the mining site to the heat power plant). In terms of the content, air suspensions at all three objects (Karakan coal cluster, Vostochny port terminal and heat power plant in Vladivostok) are very much similar – these are particles of coal, aluminum silicates and rare earths represented by monocytes (phosphates of light and, less often, heavy rare earth elements) and seldom by silicates of rare earths. The most hostile environments in terms of the grain-size and substance compositions are the areas directly adjacent to a coal production object (particles from 300 nm to 2 μm in size, with the large specific surface area up to 24903.82 cm²/cm³).
