If you are looking for the largest source of low sulfur coal in the nation, you should check out the BNSF Mine Guide 2018. This pdf document provides detailed information on the coal mines that BNSF serves, including their locations, capacities, qualities, and contacts. You can also learn more about BNSF's coal shipping services, routes, and prices on their website.
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.
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.
In the Powder River Basin, for example, coal is of insufficient thermal maturity to have generated thermogenic hydrocarbons, and geochemical data indicate that all produced gas is effectively of biogenic origin [54], [55]. Methanogenesis occurs along two major metabolic pathways: methyltype fermentation and CO 2 reduction shown in Fig.

Within a given basin, various structures tend to be associated with enhanced gas production. In the Powder River basin, folds with up to 75 m of structural relief were created by differential compaction. ... These insights are valuable for locating thicker and higherquality coal bodies, predicting whether these will be connected at a given ...
By 2003, the Powder River Basin yielded more coal than the Appalachian coal basins in the eastern United States. Both total coal production and PRB coal production peaked in 2008 and have since declined.

Coalfired power plants often utilize a specific coal quality that generators cannot easily replace with coal from other regions. While Powder River Basin coal operators have reported some success in managing costs as production footprints shrink, largescale operations have long been one of the region's primary advantages.
Coal. We help keep the lights on! BNSF is a critical component in coal delivery for electricity generation, industrial use and export. We offer efficient, reliable delivery through proven routes with broad access to western coal production. BNSF is a vital link to lowcost Powder River Basin (PRB) coal. Contacts.
In the western United States, coal beds have burned naturally in several geologic basins in the states of Wyoming, Montana, North Dakota, Colorado, Utah, New Mexico, and Arizona Sigsby, 1966, Hoffman, 1996. The most extensive burning has been in the Powder River basin (PRB) of northeast Wyoming and southeast Montana Rogers, 1918, Coates and ...

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 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. ... The USGS Energy Resources Program research ...
The Powder River Basin, or PRB, which is home to the largest coal reserves in the United States, currently supplies approximately 40 percent of the nation's coal and accounts for a full 13 ...
AREA AND GEOLOGY OF THE POWDER RIVER BASIN AND GILLETTE COAL FIELD Minable coal discussed in this study is within the Tongue River Member of the Fort Union Formation in the Powder River Basin of Wyoming and Montana (fig. 3). The Powder River Basin is an asymmetrical structural basin with an axis that trends northwestsoutheast (fig. 1) on
The Powder River Structural Basin covers an area of more than 61,000 km 2 in northern Wyoming and southern Montana (Fig. 1).The Basin is an important source of energy resources, containing the largest coal resources of any coal field in the contiguous United States (Glass, 1997) and substantial oil and natural gas technological advances have enabled economical development of ...
The purposes of this paper are to: (1) test the presumptive microbial origin of gas in subbituminous coal in the Powder River Basin, which is a prolific coalbed gas producer (Fig. 1); (2) compare results of our work to previous investigations by Rice, 1993, Gorody, 1999; (3) expand the work on isotopic composition and fractionation of deuterium (D) between water and methane (CH 4) and of ...
The Powder River Basin contains one of the largest resources of lowsulfur, lowash, subbituminous coal in the world and is the single most important coal basin in the United States.

The objective of this research is to develop a costeffective catalytic pyrolysis process for producing highquality oil and gas from coal with low CO 2 emission. Catalytic pyrolysis of the Powder River Basin coal using composite Na 2 CO 3FeCO 3 catalysts has been investigated in a fixed bed reactor between 500 and 800 °C under atmospheric pressure to evaluate effects of catalyst on quantity ...
Factors that affect TRDU product gas quality appear to be coal type, temperature, and oxygen/fuel ratios.
