Coal can be converted directly into synthetic fuels equivalent to gasoline or diesel by hydrogenation or carbonization. [100] Coal liquefaction emits more carbon dioxide than liquid fuel production from crude oil. Mixing in biomass and using carbon capture and storage (CCS) would emit slightly less than the oil process but at a high cost. [101]
In 2012 coal production in Ukraine amounted to 85.946 million tonnes, up 4.8% from 2011. [113] Coal consumption that same year grew to 61.207 million tonnes, up 6.2% compared with 2011. [113] More than 90 percent of Ukraine's coal production comes from the Donets Basin. [114] The country's coal industry employs about 500,000 people. [115]
The mine ships its coal to the adjacent Wyodak power plant and to other customers via railroad. The mine is operated by Wyodak Resources Development, a subsidiary of the Black Hills Corporation. [1] As of 2009, Wyodak had reserves of 294mm tons of sub-bituminous coal and a maximum permitted production capacity of 10mm tons per year.
Coal analysis techniques are specific analytical methods designed to measure the particular physical and chemical properties of coals. These methods are used primarily to determine the suitability of coal for coking , power generation or for iron ore smelting in the manufacture of steel .
Eight of the ten largest mines in the United States are located in the basin. Annual Production at North Antelope Rochelle was 107.7 million tons in 2012, 109.0 million tons in 2011, 105.8 million tons in 2010, and 109.3 million tons in 2015, making the North Antelope Rochelle the largest producer of coal in the United States.

The coal is next pulverized into a very fine powder. The pulverizers may be ball mills, rotating drum grinders, or other types of grinders. Some power stations burn fuel oil rather than coal. The oil must kept warm (above its pour point) in the fuel oil storage tanks to prevent the oil from congealing and becoming unpumpable. The oil is usually ...
