【 摘 要 】

The energy crisis, which becomes more evident in Russia, stems in many respects from unjustified high consumption of energy resources. Development and exploitation of principal oil and gas deposits located in remote areas with severe climatic conditions require considerable investments increasing essentially the cost of power generation. Account should be taken also of the fact that oil and gas resources are nonrenewable. An alternative fuel for heat and power generation is coal, the reserves of which in Russia are quite substantial. For this reason the coal extraction by 2020 will amount to 450-550 million tons. The use of coal, as a solid fuel for heat power plants and heating plants, is complicated by its transportation from extraction to processing and consumption sites. Remoteness of the principal coal mining areas (Kuzbass, Kansk-Achinsk field, Vorkuta) from the main centers of its consumption in the European part of the country, Siberia and Far East makes the problem of coal transportation urgent. Of all possible transportation methods (railway, conveyor, pipeline), the most efficient is hydrotransport which provides continuous transportation at comparatively low capital and working costs, as confirmed by construction and operation of extended coal pipelines in many countries.
