Abstract

The article examines the reasons leading to the increase in the price of fuel and energy resources consumed in the Arctic regions of the Yakutia. The paper studies the conditions for the development of coal deposits in the region. It is shown the lack of open cast mines that meet modern criteria for efficient use of small-scale open mining by quality and logistic accessibility. This article determines that with the minimum level of clogging of the hard coal mined and the stabilization of its quality over time, it is possible to efficiently recycle the fuel without other precombustion measures. In the case of development of brown coal deposits, additional enrichment is required after extraction to improve the level of consumables. The paper stresses that development of local small-scale deposits of coal is important direction to improve energetic safety of arctic regions. It is necessary to select the coal mines most suitable for open-cast mining, as close to consumers and also with the best quality indicators. The use of the specified measures of technological and economic management, administrative regulation and improvement of mechanisms of «northern delivery» make it possible to facilitate the creation and operation of new coal mines in the Arctic zone of Yakutia. In turn, this reduce coal delivery periods, its quantity and quality losses in the supply chain, and improve local fuel and energy complexes.
