Abstract

The composition and properties of black coals from the Khingui coal manifestation were evaluated. It was found that the test coals are noncaking low-sulfur (Sd to 0.49%) coals with a high yield of volatile substances (V daf= 43.52–51.42%). The high heat value of coal is Q daf s = 22.6–32.8 MJ/kg, and the low heat value Q r i on an as received basis is 11.7–20.6 MJ/kg. The humic acid content varies from 5.63 to 44.73%. The results of the analysis of the mineral matter of coal and ecologically harmful elements are given.
