Patriot Coal says it expects to lay off more than 2,000 workers in West Virginia.
Patriot issued layoff warning notices in the counties of Boone and Kanawha this week.
Kanawha County Commission President Kent Carper says 1,065 workers in his county will lose their jobs. There will be 483 layoffs at Speed Mining LLC in Dawes, 288 at Wildcat Energy in Eskdale, 161 at Midland Trail Energy, 118 at Remington LLC in Eskdale and six at Little Creek Dock in Charleston.
Assistant Boone County administrator Pam White says 970 workers in her county will be affected.
Patriot filed for Chapter 11 bankruptcy in May.
Patriot says the warning notices are conditional because it doesn't yet know who will purchase its assets or what the purchaser's hiring plans will be.
