The characteristics and the composition of the mineral substances forming the internal and external ash content of the coal have been studied. A quantitative estimate is given of the mineralogical composition of the inorganic fraction. It is shown that uryup brown coal is characterized by a high concentration of various elements of the mineral fraction in compounds with humic acids.
