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 ...
