INTEGRATED DEVELOPMENT PROSPECTS FOR POGRANICHNOE BROWN COAL DEPOSIT IN TRANSBAIKALIA

The integrated use of coal is the most important direction of increasing production efficiency, which expands raw material supply, increases production range, enhances profitability of coal mining and processing, reduces harmful emissions into the atmosphere and diminishes areas occupied by coal processing waste. Coals contain considerable group of trace elements at concentrations significantly higher than their average content in the crust and sedimentary rocks. This circumstance is governed by the fact that the geochemical environment in coal-bearing strata is favorable for the accumulation of trace elements as compared the average background of the earth’s crust. Trace elements are characterized by uneven distribution in coals not only per various deposits but even within a seam of a deposit, which is typical of coal deposits in Transbaikalia. In Transbaikalia, coal is the primary source of power production without any alternative in the future. In addition, brown coals of Transbaikalia are characterized by very high and high contents of germanium and other rare and trace elements. This article discusses in detail Pogranichnoe brown coal deposit as an integrated development project in the main areas of coal use: power production and industry. The preliminary estimate of germanium, gallium and beryllium distribution in coal seams is given.
