Transcript | One of the layers under exploitation has a depth of from 60 to 1.4 metres, while another has a depth of 5 to 8 metres. The great variety of coal to be found there includes: (1) brown and bituminous coal, especially predominant in the Khakharei deposits, with supplies of about 75 million tons in the Priangara region, remarkable for its high percentage of volatile substances (42-82 per cent). The lignite contains up to 12-14 per cent ash and moisture. In places, the bituminous coals yield a badly caking coke. The calorific value is from 6,000 to 6,600 calories. The total deposits are estimated at 52 billion tons, of which 385 million tons, or about 0.7 per cent, are classed as actual. Only the central portion has been covered by detailed geological investigation, a territory extending over 71 sq. km. (out of a total area of 25,000 sq. km.). Mining operations in the district are insignificant in scope. In 1926—27 658,711 tons were mined, although this district occupies first place among Siberian coal mining operations. East Siberia, from Lake Baikal to the Pacific Ocean, contains numerous small deposits of coal scattered in isolated groups: (1) The Trans-Baikal region with coal deposits of the Jurassic age containing brown coal (calorific value about 5,000 calories) with a considerable percentage of ash. Total reserves are about 320 million tons. (2) The Amur River region, containing brown coal of the Tertiary age with deposits totaling 375 million tons. (3) The Maritime region where numerous deposits of bituminous and brown coal are known to exist, the most important being the deposits of the district of Vladivostok. In this district 9 deposits are being worked out of a total of 13 coal deposits existing in the whole of the Far Eastern region. The total coal reserves here are estimated at 615 29 |
