Abstract

The composition and properties of coal from the Bodonskoe deposit were studied. It was shown that this is low-sulfur (Sd = 0.3–1.0%) and medium-ash grade 1B brown coal with a high yield of volatile substances (Vdaf = 56.1–60.9%). The humic acid content varies from 32.3 to 50.8%. The heat of combustion of coal is Q s daf= 26.0–27.4 MJ/kg. The concentrations of toxic elements in the coal samples are at a background level.
