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
The basin covers about 19,500 square miles, exclusive of the part of the basin within the Crow and Northern Cheyenne Indian Reservations in Montana. The Powder River Basin, which contains the largest resources of lowsulfur, lowash, subbituminous coal in the United States, is the single most important coal basin in the United States.
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 ...
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.
