· Both coal pretreated for 12 and 16 h produced methane with 240 μmol/g coal, which increased methane production by about % compared with the raw coal. Based on these results, 12 h would be the best time for NaOH pretreatment. More treatment time with M NaOH had less effect on methane production, suggesting the effect of NaOH on coal structure was no longer .

The amount of gas dissolved in the coal increases with increasing CO2 pressure. TPDMS showed that CO2 desorption from the Wyodak coal follows a first order kinetic model. Increase in the ...
North Antelope Rochelle is the highest production coal mine in the country, and the accident was the first coal mining fatality in the state since a 2008 accident at the Wyodak Mine. While the exact cause is still being investigated by several state and federal organizations, it appears that a failure of the cables on the tongs may have contributed to the accident.

The Powder River Coal Region of northeastern Wyoming and southwestern Montana contains North America''s thickest and most extensive lowsulfur coal seams, including the seventyfootthick Wyodak seam, and the region''s 269 million–ton production accounts for 70 percent of Plains production and 23 percent of combined Canadian production. Most of the coal is transported out of state, with ...

Energy Production; Wyodak Resources; History of the Wyodak Mine . The Wyodak Mine is nestled in the Powder River Basin. Coal deposits within the Powder River Basin were discovered at the end of the 19th century, and these deposits contain the largest source of coal in the United States. Mining operations at the mine site first began in about 1918 with the establishment of the Peerless Mine, an ...
Phosphomolybdic acid (PMA) has been found to be a very effective catalyst precursor for direct liquefaction of Wyodak coal. A concentration of 300 mg Mo/kg maf coal of PMA imparts greater activity when impregnated onto the coal compared to adding the crystalline solid directly to the reaction mixture. Significant improvement in the reaction occurred only when H2S was added to the reaction ...
Abstract The production of both over and undersized coal fragments is a constant problem to open pit operators in the Powder River Basin. Operators strive to achieve production blasts that economically minimize the weight percentage of over and undersize coal. However, natural fractures influence blast fragmentation, and can impose limits on the final fragment size distribution.
Wyodak claims the Department improperly applied Wyoming law when it set the point of valuation for its coal for production years 2009 through 2011. It also challenges the Department''s categorization of certain governmentimposed and environmental expenses in the tax valuation formula. The Board of Equalization (Board) upheld the Department''s determinations, and Wyodak petitioned for ...
· We use frontend loaders to mine the coal. The loaders place the coal into an inpit crusher. It''s then transported by conveyor to the adjacent power plant complex. Wyodak''s coal seam is approximately 80 feet thick, and average daily production is between 11,000 and 12,000 tons.
