A coal mine in the Powder River Basin has received state recognition for its reclamation efforts. The Wyoming Department of Environmental Quality (DEQ) recognized the Coal Creek Mine with its 2022 Excellence in Mining Reclamation Award for coal. Coal Creek Mine is operated by Thunder Basin Coal Company south of Gillette.
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 ...
These coal deposits are the thickest in the Powder River Basin (PRB), where Fort Union coal beds like the Big George coal and the Wasatch Formation's Lake DeSmet coal bed can be more than 200 feet thick.

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 ...

Coal. Wyoming, the nation's leading coal producer since 1986, provides about 40% of America's coal through the top 10 producing mines located in the Powder River Basin. Most Wyoming coal is subbituminous, which makes it an attractive choice for power plants because it has less sulfur and burns at around 8,400 to 8,800 BTUs per pound.
The Future of Coal in the Powder River Basin. Currently for Campbell County, the 2013 Wyoming Business Directory lists nine different coal mining companies, mostly in Gillette. Among these are Alpha Coal West, Arch Coal Inc., Cloud Peak Energy, Foundation Coal West and Powder River Coal. Eighteen oil and gas producers are listed, including two ...
Examination of a fly ash derived from the combustion of a lowS, subbituminous Powder River Basin coal by Scanning Electron Microscopy (SEM) and Highresolution Transmission Electron Microscopy (HRTEM), both supplemented by Energydispersive Xray spectroscopy (EDS), showed that the fly ashes were dominated by amorphous phases, Carich plagioclase feldspars, Mgrich phases, complex CaMgAlSi ...
Powder River Basin The Powder River Basin (PRB) of Wyoming and Montanta is the largest low sulfur coal source in the nation. Eight of the ten largest mines in the United States are located in the PRB.
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.
Powder River Basin coal production increased in the months of July through September, mining just shy of 61 million tons out of 12 Wyoming PRB mines, according to data from the Mine Safety...
Powder River Basin Coal on the Move No other coal deposit on the planet is so big, so close to the surface and so cheap to mine as the rich seams in eastern Wyoming and southern Montana. And...
North Antelope Rochelle Mine sits in the Powder River Basin. The Powder River Basin of Wyoming and Montana is the largest lowsulfur coal source in the nation. Eight of the ten largest mines in the United States are located in the basin. Peabody Energy opened the North Antelope Mine in the heart of Wyoming's Powder River Basin in 1983. The ...
The revised USGS assessment methodology resulted in an estimated original resource of about trillion short tons in the Powder River Basin, of which 162 billion short tons are considered recoverable resources (coal reserve base) at a stripping ratio of 10:1 or less.
Powder River Basin is a major coalbearing geologic structure underlying southeast Montana and northeast Wyoming, accounting for more than 40% of the country's coal reserves. The Powder River Basin (PRB) was formed during Late Cretaceous to early Tertiary during tectonic uplift. In the Paleozoic and Mesozoic, the area began as a stable ...
Powder River Basin (PRB) coal is classified as " subbituminous " and contains an average of approximately 8,500 btu/lb, with low sulfur. Contrast this with eastern, Appalachian bituminous coal containing an average of 12,500 btu/lb and high sulfur.
GILLETTE — Coal production in the Powder River Basin saw growth in 2021 after a significant pandemicrelated setback marred the extraction industry the year before. Amid an overall downturn in ...
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 top five coal producing states and their percentage shares of total coal production in 2021 were: Wyoming 41%; West Virginia 14%; Pennsylvania 7%; Illinois 6%; Montana 5%; Coal is mainly found in three regions: the Appalachian coal region, the Interior coal region, and the Western coal region (includes the Powder River Basin).
Sixteen mines in the Powder River Basin produce 43% of coal Source: Energy Information Administration and Mine Safety Health Administration (MSHA) More than 40% of coal produced in the United States comes from 16 mines in the Powder River Basin (PRB), a mining region primarily located in northeast Wyoming and southeast Montana.

In Recent and Ancient Nonmarine Depositional Environments: Models for Exploration. SEPM (Society of Sedimentary Geology) Special Publication 31, pp. 169190.
Today, most coal rights, including onethird of reserves, are owned by the federal government, but in the Powder River Basin, it's even more concentrated.
Powder River Basin (PRB) coal also includes beds in the Eoceneage Wasatch Formation, where exploration drilling has encountered coal seams greater than 200 feet thick. Coal is mined in the PRB at a rate of 12 tons per second, filling between 50 to 70 coal trains per day. Seven of the nation's 10 largest coal mines operate in the Wyoming part ...
More than a million tons of publiclyowned federal coal leaves Wyoming's Powder River Basin each day, bound for power plants across the nation. It's a big part of the state's economy and the nation's energy mixbut it also takes a toll on our state. Concerns about coal development were the driving force behind the formation of the ...
The coal geology in the basin is complex, which makes correlation with individual seams difficult at times. Although more than 12,000 wells have been drilled to date, large areas of the Powder River Basin remain relatively undeveloped. ... The Powder River Basin in northeastern Wyoming is one of the most active areas of coalbed natural gas ...

Look at a map and you will find two Powder River Basin coal fields. Not far away, there is a small one in Montana and one in Wyoming. What railfans call PRB ist exact the SOUTHERN POWDER RIVER BASIN between Gilette and Orin in Wyoming. UP, like many others, use also the shortversion SPRB! Coal production in 2002 in the NPRB: 5 million tons.
