A stratigraphic section of the Powder Creek Basin can be found at the Wyoming Geological Survey website. A common type of rock found in this basin is called "scoria" colloquially known as "red dog,". It is red from oxidation of iron, which causes the rock to rust. The area is rich in coal, and the coal sometimes burns naturally due to ...
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. This is the same as for subbituminous coal in Colorado, but slightly below that in Montana. The lowest emission factor for subbituminous coal is in Utah () and the highest ...
The subbituminous PRB coal examined in this study was collected from the Antelope Mine in the Powder River Basin, Wyoming, by CQ, Inc. A commercial laboratory produced a simulated cleaned coal by combining various floatsink fractions according to CQ, Inc.'s specifications. Initial project tasks included (1) obtaining semi
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 future of energy production in parts of Wyoming and Montana remains uncertain following a court ruling last week. A federal judge rejected the Bureau of Land Management's (BLM) two resource management plans for the Powder River Basin, which is a region in Wyoming and Montana that produces more than 40 percent of coal.. District Judge Brian Morris said the BLM failed to properly ...

The trend toward increased use of Powder River Basin coals, even in the Eastern United States, has led to newer boilers being designed to operate within broader ranges of fuel types and quality. Tangentially fired boilers can also accommodate a broader range of fuel types and quality.
Loadings in the Powder River Basin averaged trains/day in the most recent reporting week, a % decrease week on week and the lowest level since an average trains/day were loaded in the week ended May 28. Cumulative PRB loadings this year were at an average trains/day, up from trains/day in the same period a year ago.
This 37,500squaremile region known as the Powder River Basin is home to some of the largest coal mines in the world, and it supplies around 40% of the country's 700 million tons annually.

• Resource tables for the WyodakAnderson coal zone in the Powder River Basin include coal and overburden thickness categories from Wood and others (1983), which are based on apparent coal rank. Additional categories have been added to provide more detail. Resources are also reported by State, county, Federal
Industry data hammer home the quantitative reality of the shift. From 2008 to 2019, the pulse of coal out of the Powder River Basin has slowed from about 80 trains per day to 50 trains, according to railroad industry data. Trendlines point to a continuing decline in PRB coal as utilities across the nation shift to natural gas and renewables.

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.
The coal beds in the Powder River Basin are shaped like half a bowl sliced vertically. A mine starts at the top of the bowl, where coal is near the surface, but as it moves it digs progressively deeper until it reaches the bottom. The overburden (rock and sediment on top of the coal) is loosened by dynamite charges that shake the ground for ...
