Abstract
Physicochemical properties of coal dust sampled from the fine filter of the mine degassing plant of the Kuznetsk coal basin were explored. The coal dust sample was thoroughly characterised by scanning electron microscopy and atomic emission spectroscopy; technical analysis was also carried out and granulometric composition was determined. Relationships were found between changing the chemical composition of mineral components of the mineral portion of coal dust and coal particle size relying on the data acquired.
