The biggest coal deposit by volume is the Powder River Basin in Wyoming and Montana, which the USGS estimated to have trillion short tons of inplace coal resources, 162 billion short tons of recoverable coal resources, and 25 billion short tons of economic coal resources (also called reserves) in 2013. The coal in the Powder River Basin is subbituminous in rank.
Gas content in the Powder River Basin is much lower than in the San Juan Basin (Table ), but the large production of gas in the Powder River Basin suggests that low gas content is compensated by large coal volumes. This also suggests that the Powder River Basin may feature a significant contribution of free (, not adsorbed) gas in its coal.
Coal in the Powder River Basin. The Powder River Basin in the Red Desert stretches for more than 14 million acres from the peaks of Wyoming's Bighorn Mountains to the Yellowstone River in eastern Montana. It provides premier habitat for elk, mule deer, pronghorn antelope, wild turkeys, and the threatened greater sagegrouse in places like Otter ...
Arch Resources' Coal Creek mine in the Powder River Basin, pictured here in December of 2019, is slated for closure in 2022. (Dustin Bleizeffer) The reality of a permanently shrinking Powder River Basin coal industry came into sharper focus on Tuesday with Arch Resources announcing it is speeding up preparations to close its Coal Creek mine.
During the production of CBM, water is pumped from wells, lowering hydrostatic pressure in the coal beds and allowing the previously confined methane that is stored within the internal surfaces and voids of the coal to flow (DeBruin and others, 2000). ... The effect of CBM discharge waters on streamwater quality in the Powder River Basin is ...
The coal mines in the Powder River Basin produce about 40% of the nation's thermal coal, but production volumes have been declining for years. Natural gas and renewable energy have gradually ...

(Stricker and Ellis 1999). Coal quality data from the WyodakAnderson coal indicate that the coal is subbituminous, generally low sulfur, and has low ...
Subbituminous coal is the predominant rank of coal produced west of the Mississippi River, accounting for 62 percent of the region's total coal output in 1992. Subbituminous coal in Wyoming's Powder River Basin, the principal source of this rank of coal, has an emission factor of pounds of carbon dioxide per million Btu.

The Powder River Basin coal boom started in the 1970s. The biggest mine by production volume, Black Thunder, opened in 1977. The company town of Wright sprang up at nearby Reno Junction, beginning with the 108unit Cottonwood Mobile Home Park. As of 2012 there are 13 operating coalmines in the Powder River Basin in Wyoming.
