Although no underground mining in the Powder River Basin is expected to occur in the foreseeable future, a substantial, deeper coal resource in beds 1020 feet thick is estimated at 304 billion short tons in the region.
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.
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.
Ninetyfive percent of the coal hauled by BNSF comes from the Powder River Basin in Montana and Wyoming. This is the largest deposit in the United States, supplying about 40 percent of its coal. Powder River Basin coal is subbituminous and low in sulfur, making it some of the cleanestburning coal available in the United States. BNSF serves 21 ...
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 ...
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 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 QGESS coal specification selection process was based on the following criteria: 1. Recommendations for QGESS were selected from the coal analyses most commonly used ... sulfur, nearsurface, and thick subbituminous coal seams of the Powder River Basin (PRB). The Rocky Mountain province comprises the coal fields of mountainous areas of Montana,
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.

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.
The glacial aquifer system covers the northeastern part of the Williston structural basin. The lower Tertiary and Upper Cretaceous aquifer systems are present in about 91,300 square miles (mi 2) of the Williston structural basin and about 25,500 mi 2 of the Powder River structural basin. Directly under these aquifer systems are 800 to more than ...
The results of the study show that coal fly ash created from the combustion of Powder River Basin coal holds promise as an economic source of REEs. "We have really important work going on in SER and across UW through some key collaborations," says SER's Davin Bagdonas, the lead author on the study.

When the USGS data was first compiled, in 2013, Powder River Basin coal was selling for a ton, resulting in about 23 billion tons being designated as economicallyrecoverable. With coal prices down to a ton, the reserve estimate has plummeted to just 16 billion tons, Haacke said. That's equivalent to 40 years at the current ...
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 ...
