"VORKUTAUGOL" (RU: "Воркутауголь") is the productive consortium for the extraction of the coal of the Ministry of the Coal Industry of the USSR, within the Komi ASSR. The major industrial and administrative centre is the Vorkuta city. The consortium has been established during the 1974. The consortium includes the 15 underground mines, the PechorNIIproekt scientific-researching institute, and other institutes. The underground mines of the "Vorkutaugol" consortium develop the Vorkutinskoe, Vorgashorskoe, Yunyaginskoe, and Halmeryuskoe deposits, which are containing the 26 layers with the total thickness of 48 metres, with the median dynamic thickness of 2.3 metres, and with the angle of the dip from 2 to 90 degrees. The majority of the coals, which are extracted, belong to the ZH and K marks; the coals are coking, with the low sulfur content (0.6-0.8%), with the low phosphorus content (0.002-0.03%), and with the ash content of 16% on average. The places of the development are distinguished with the complicated hydrogeological conditions (the water abundance is 70-600 cubic metres per hour), and with the tectonic disturbances in the form of the individual dip-slip fault zones. The majority of the underground mines are beyond the categories in terms of the methane, and are dangerous because of the mine bumps and outbursts of the coal and gas. The average depth of the development is 550 metres, the maximal depth is 800 metres. The predominant system of the development (see the Figure) is with the long pillars along the strike (up to 2000 metres); there are also used the continuous and combined systems, the layered and shielded methods for the excavation.
At the retreat mining cleaning works, there are used the KM-87, MK-97N, "Donbass", 1MK, 2MKE, and 1ASCH mechanized complexes, the 1K-101, and 2K-52M combined cutting-loading machines with the individual roof support, and others. The level of the extraction using the mechanized complexes is 97.1% (1981). The penetration of the mine workings is conducted using the combined cutting-loading machines (67.9%); the underground transport is of the conveyor type, and of the electric locomotive type.
The consortium has been awarded with the Order of Lenin (1966).
