Abstract

The paper presents a mathematical model developed by the authors. The model intended for evaluation of changes in the lowest coal heating value was tested on the hard coal from the Dzhebariki-Khaya deposit, the Republic of Sakha (Yakutia)). This coal is transported uncovered to the overwhelming majority of consumers located in the Yan river basin. The developed model can be applied to technically and economically assess the fuel supply to the remote hard-to-reach consumers in Russia’s Far North. It takes into account seasonal variation in the mass fraction of external moisture and dynamics of chemical oxidation through the empiric model of change in the ash content of the coal in the case of outdoor storage. The paper also describes an existing scheme for coal delivery to the regions of Russia’s Far North and main risks of the fuel supply.
