The granulometric composition of the powders of GZhO, OS, and G coals was measured by a laser
diffraction method upon the dispersion of samples in an aqueous medium with the addition of a Dusazin 901
surfactant (Fritsch, Germany). The metrological evaluation of the results of determinations by coal-sizing
analysis and the laser diffraction method was performed. It was shown that satisfactory results were obtained
for the samples of GZhO and G coals in all of the determination ranges. For the samples of OS coal, the limit
of reproducibility between the two methods in ranges of 0.074 + 0 and –0.20 + 0.10 mm was exceeded by factors
of 1.5 and 1.2, respectively.
