The Dry Fork mine is a coal mine located 8 miles north of Gillette, Wyoming in the United States in the coal-rich Powder River Basin . The mine is an open pit mine that utilizes truck and shovel mining method to mine a low-sulfur, sub-bituminous coal that is used for domestic energy generation and shipped to customers via railroad. In 2011, the mine began supplying coal to the newly constructed Dry Fork power station that was constructed adjacent to the mine. The mine is currently owned and operated by Western Fuels Association .
4-488: As of 2009, Dry Fork had reserves of 330 mm tons of sub-bituminous coal and a maximum permitted production capacity of 15mm tons per year. Typical annual production has been in 5.2mm ton range for the last several years though. In 2008, the mine produced just over 5.2 million short tons of coal, making it the 37th-largest producer of coal in the United States. The average quality of the coal shipped from Dry Fork
8-498: Is 8,050-8,200 BTU/lb, 0.20-0.42% Sulfur, 3.8-5.1% Ash, and 1.50% Sodium (of the ash). Train loading operations at the mine are done with a batch weigh bin system that is coupled to a "weigh-in-motion" track scale system. Silo capacity at the mine's rail loop, which can accommodate a single unit train, is 10,800 tons. The Dry Fork mine shipped its first coal to members of the Western Fuels Association in 1990 and
12-601: Is run by Western Fuels-Wyoming an associate of Western Fuels. Since opening, Dry Fork has shipped 69.5mm tons of coal. Short ton The short ton (abbreviation tn ) is a measurement unit equal to 2,000 pounds (907.18 kg). It is commonly used in the United States , where it is known simply as a ton; however, the term is ambiguous, the single word " ton " being variously used for short, long , and metric tons. The various tons are defined as units of mass. They are sometimes used as units of weight ,
16-616: The force exerted by a mass at standard gravity (e.g., short ton-force). One short ton exerts a weight at one standard gravity of 2,000 pound-force (lbf) . In the United States , a short ton is usually known simply as a "ton", without distinguishing it from the tonne (1,000 kilograms or 2,204.62 pounds), known there as the "metric ton", or the long ton also known as the "imperial ton" (2,240 pounds or 1,016.05 kilograms). There are, however, some U.S. applications where unspecified tons normally mean long tons (for example, naval ships) or metric tons (world grain production figures). Both
