Black Thunder is the second most productive mine in the United States, providing the U.S. with eight percent of its coal supply. In 2007, the mine produced 86,196,275 short tons (78.2 million metric tonnes) of coal, nearly 20 percent of Wyoming's total coal production, and higher than 23 other individual coal producing states.
Black Thunder’s dragline excavator is the biggest in the world and cranks out enough coal to load up 25 miles of railroad cars per day.. Draglines are not used to dig coal but only strip overburden. Black Thunder operates six draglines, not just one. Coal is excavated by power shovels and loaded into haul trucks.
In 2009, the America’s Power Factuality Tour stopped at the Black Thunder Coal Mine to report on its role in generating electricity in the United States.
In 2010, the Black Thunder Mine dug up an estimated 115 million tons of coal, an increase of 34 million tons over 2009. The increase was a result of merging the Jacobs Ranch Mine - and its average 38 million tons per year - into the Black Thunder's annual production. With the acquisition of Jacobs Ranch Mine, Black Thunder is now the world's top coal producer.(5)

Famous quotes containing the words black, thunder and/or coal:
“We are all androgynous, not only because we are all born of a woman impregnated by the seed of a man but because each of us, helplessly and forever, contains the other—male in female, female in male, white in black and black in white. We are a part of each other. Many of my countrymen appear to find this fact exceedingly inconvenient and even unfair, and so, very often, do I. But none of us can do anything about it.”
—James Baldwin (1924–1987)
“Here falling houses thunder on your head,
And here a female atheist talks you dead.”
—Samuel Johnson (1709–1784)
“And in their blazing solitude
The stars sang in their sockets through the night:
“Blow bright, blow bright
The coal of this unquickened world.””
—Philip Larkin (1922–1986)
