Laboratory installation for collection and concentration of airborne coal dust

Coal dusting is one of the urgent problems of the coal industry, since coal dust can pollute the air, soils and water objects. In accordance with SanPiN 1.2.3685-21, coal dust is included in the list of air pollutants. It was noted that there are no marker substances for soils and water objects, indicating that coal dust is the source of their pollution. The availability of information on the content of airborne dust in coals, its granulometric composition and the concentration of potentially hazardous elements will make it possible to identify a list of marker substances, i.e. potential pollutants of soils and water objects. This article describes a new laboratory installation designed to capture and concentrate fine dust contained in ordinary coals or commercial products that is capable of being in an airborne state. Experimental results studies on a laboratory installation for trapping suspended coal dust from commercial coals are presented. The quantitative content of airborne dust in coals of different rank was determined, granulometric composition of dust samples was analyzed. It has been established that, in comparison with the original coals, dust is characterized by a higher ash contents, and the sulfur content in it changes insignificantly.

Keywords: laboratory installation, airborne coal dust, concentration, identification, potentially hazardous elements, sieve analysis, regulation, environmental damage.
