Features of the transport system of the Republic of Sakha (Yakutia) and the substantiation of the need for searching of ways to increase the reliability of coal supply

Abstract

The article describes the transport corridors of coal delivery to remote hard-to-reach consumers of the Republic of Sakha (Yakutia). A brief description of the waterways and the timing of their operation are given. The conditions of functioning of winter roads are reflected. The main risks of coal delivery are described. The article describes the whole cycle of finding coal in the open air from the moment of production to the final consumption in boiler houses. The results of experimental analysis and modeling of oxidation state during delivery are presented. The economic inexpediency of forming long-term coal reserves is explained, while maintaining the traditional technology of transportation and storage. The economic difficulties of the organization of coal supply have been singled out. As a result of the analysis of the current state of coal supply, key points of improving the coal supply system of the Republic of Sakha (Yakutia) are highlighted.

Russian Arctic region energy balance (Republic of Sakha (Yakutia))

“…On delivery, 4-10% of coal is lost. Due to the duration of delivery there is a decrease in the quality of coal [6][7][8][9][10]. The decrease in coal quality is primarily due to oxidation processes.…”
