Montana produces primarily subbituminous coal from the Powder River Basin Powder River Basin coal has a lower heat content compared to other coal basins, but it burns cleaner because of its relatively low sulfur content.

Powder River Basin: Part One (BNSF) Not that long ago (early 21st century), as many as 100 or more coal trains per day ran into and out of the Powder River Basin. You could plant yourself anywhere along the tracks from Shawnee Junction to Donkey Creek and, during a busy hour, see 810 trains. In a "slow" hour, you might see three.

The Powder River Basin is a geologic structural basin in southeast Montana and northeast Wyoming, about 120 miles (190 km) east to west and 200 miles (320 km) north to south, known for its extensive coal reserves. The former hunting grounds of the Oglala Lakota, the area is very sparsely populated and is known for its rolling grasslands and ...

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.
Most of the coal produced in the PRB supports electric power generation in the United States. Starting in the 1990s, many coalfired power plants switched to subbituminous coal from the PRB—which has relatively low sulfur content—to meet tightening Clean Air Act emission 2003, the Powder River Basin yielded more coal than the Appalachian coal basins in the eastern United States.
The most important distinction between this Powder River Basin coal assessment and other, prior assessments, was the inclusion of mining and economic analyses to develop an estimate of the portion of the total resource that is potentially recoverable, not just the original (inplace) resources. Prior resource assessments relied on net coal ...
The Powder River Basin coalbed methane boom in the early 2000s stirred controversies over land rights, mineral rights, environmental stewardship, the disposal of water and—at every turn—politics. Now, few of the 29,000 wells drilled produce much gas and around 3,000 wells are abandoned and left to the state to clean up.
Wyoming's First Coal Bust. During Wyoming's halcyon days of coal in 2008, Powder River Basin mines collectively filled more than 100 twomile long trains per day and sent them rolling to power plants in 36 states. After 11 years of decline, the daily pulse of coal trains out of the basin slowed to fewer than 50.
Powder River Basin, Wyoming Coal Assessment. In 2009, the USGS completed the first digital National Coal Resource Assessment (NCRA) of inplace coal resources. The current generation of coal assessments will not only be a refinement of the coal resources, but also the systematic determination of the regional coal reserve base in all the ...

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 Powder River Basin (PRB), located in the western United States, is a coal mining region that has evolved throughout the half century since the first largescale mine began in the 1970s, as shown in Fig. related to commodity pricing, high inflationary periods and, more recently, low demand, associated with power producers switching from coal to natural gas or renewable energy ...

Coal mine in the Powder River Basin of Wyoming and Montana(Credit: USGS. Public domain.) In our 2015 Powder River Basin assessment, we met the challenges of changing prices by including a cost curve that would allow readers to estimate what portions of the recoverable coal resources could be considered reserves at various price points.
Coal and coal byproducts from the Powder River Basin (PRB) of Wyoming are potential sources of REE but lack complete characterization of mineral hosts including ionadsorption clays (IACs). IACs, which provide a substantial portion of the global REE supply, form when hydrated REE complexes are physiosorbed to negatively charged sites on clay ...
Major coal producers have read the coal market trends and have begun to adapt, too, Feaster said. Both Arch Resources and Peabody Energy — which, combined, make up more than half the coal production in the Powder River Basin — have focused their capital spending on metallurgical coal.
