"GILLETTE, Wyo. — About 465 coal mine workers are being laid off from the two largest mines in northeast Wyoming as declining prices and demand for coal force mining companies to scale back their operations.

Peabody Energy announced Thursday it was laying off about 235 employees at its North Antelope Rochelle mine, and Arch Coal said it was reducing 230 positions at its Black Thunder mine.

Both mines are in the coal-rich Powder River Basin in Campbell County, and each employs more than 1,000 workers. Together, they produce about 200 million tons of coal a year.

The layoffs represent about 15 percent of their workforces at the mine."
