Abstract

Three coal basins in East Siberia, the Russia Lena, Kansk-Achinsk and South-Yakutsk basins, are huge coal basins which contain various sorts of both brown and high quality subbituminous and bituminous coals with low ash and sulfur content. The coals have great industrial significance for the production of energy, coke and chemicals. However, these coals are less characterized in terms of the content and distribution of trace metals, some of which are of industrial significance, other metals are toxic and radioactive. The data on the distribution of trace metals in these three coal basins, their geochemical occurrence and the behavior in chemical treatment and burning are presented in the paper. Separate coals were found to contain a large amount of valuable metals such as Ge (up to 1,400 g/ton of ash), V (up to 1,400 g/t), Sc (up to 220 g/t), Nb (up to 280 g/t), Cr (up to 1,300 g/t), Co (up to 320 g/t), Ni (580 g/t) and thus could be an industrial source of metal production. The methods for the extraction of Ge, Sc, Y, Nb and other metals prior or after combustion are described. The aspects of coal characterization in terms of toxic and radioactive impact onmore » the environment are discussed.« less

Development of fuel-energy complexes of Siberia and the Far East

Journal Article Semenov, L - Coke Chem. USSR (Engl. Transl.); (United States)

The Energy Program provides for the long-term formation of regional fuel-energy complexes on the basis of large-scale development of coal production by the open-pit method in the Kuznetsk, Kansk-Achinsk and South Yakutsk coalfields. In 10-15 years over half of all the coal in the country will be produced in these coal fields, as well as the Ekubastuz field in Kazakhatan. A feature of the historically developed placement of productive forces is concentration of industry and population in the European part of the country and the principal natural resources in the East.

The characterization of brown coals of Kansk-Achinsk Basin for improved utilization in the coal-burning power stations

Conference Solntsev, S; Shorokhov, V

Kansk-Achinsk Brown Coal Basin in Siberia is the largest one of Russia. There are several large deposits in the Basin. Two main open cuts currently annually supply 35 million tonnes of brown coal for the pulverized fired boilers operated by number of Power Stations in Central Siberia. The main part of Kansk-Achinsk brown coals are characterized by low sulfur, nitrogen and heavy metal content. However, they differ in the ash content (within the range of 4--12%) and in the ash composition (in Ca, Al, Fe, Na, in particular). This has a major influence on the boiler fouling and slagging tendency.more »« less
Problems of phytostratigraphy and the correlation of the Lower Jurassic continental sediments in West Siberia and Kuznetsk and Kansk-Achinsk basins

Journal Article Mogutcheva, N - Stratigraphy and Geological Correlation (English Translation)

Paleofloral and palynological records of Lower Jurassic sediments in West Siberia, Kuznetsk (Kuzbass), and Kansk-Achinsk basins and their correlation are discussed. In a number of recent papers dedicated to the Jurassic stratigraphy of Siberia this problem is ambiguously treated. The reference palynological scale has been developed for the Jurassic West Siberian sediments and an uninterrupted succession of floral assemblages associated with it and with regional stratigraphic units has been recognized. On this basis the scheme of the correlation between the Lower Jurassic sediments of the Kansk-Achinsk and Kuznetsk basins and West Siberia permitting a better age estimate of coal-bearing deposits,more » is proposed.« less

Review of the Soviet coal industry in 1985

Journal Article Shabad, T - Int. Geol. Rev.; (United States)

The Soviet coal industry, after having stalled for six years, managed to resume growth in production in 1985 to reach a new high point of 726 million metric tons of gross mine output. This corresponded to a 1985 goal of 726 million tons and represented a rise of about 2%. The previous high, 723.6 million tons, was achieved in 1978. Because of Soviet secrecy, detailed coal mining data on regions and basins are not available, but most of the current increases appear to be coming from eastern strip mines in Siberia, especially the Kansk-Achinsk lignite basin, and the Ekibastuz subbituminousmore »« less
Parameters of the industrial classification of the coals of eastern Siberia and the Kansk-Achinsk basin

Journal Article Svyatets, I; Agroskin, A - Solid Fuel Chem. (Engl. Transl.); (United States)

The proposed classification has been constructed according to the coding principle. Each type of coal is denoted by a three-symbol index. The first figure expresses the degree of coalification, the second the petrographic composition, and the third the degree of oxidation. The classification permits the determination of the methods of utilizing various types of coals of Eastern Siberia and the Kansk-Achinsk basin. Extensive analyzed data are tabulated and evaluated. 10 refs.
