A Wyoming coal mine in the Powder River Basin broke a coal production record last month.
The North Rochelle-Antelope mine shipped 10 million short tons of coal in March, a monthly production record for the Peabody Energy Corp.-owned mine, a company official official told a reporter from Platts, which covers the industry, on April 6.
The mine, second largest in the U.S. as measured by production numbers, loaded 641 trains with a total of 10.06 million tons of coal, said John Hull, Peabody's vice president of transportation.
The mine usually produces 8million to 9 million tons a month, he said.
North Antelope Rochelle produced 105.8 million tons of coal in 2010, according to data from the U.S. Mine Safety and Health Administration.
Platts, a journalism organization that covers the energy, shipping and metals industries, published news of the record online April 7.
Peabody spokeswoman Meg Gallagher wouldn't confirm the totals to the Star-Tribune this week, citing a need for the company to not announce such things prior to its quarterly earnings announcement next week.
