Alpha Natural Resources has completed sealing the West Virginia mine where an explosion killed 29 workers in 2010.
Alpha spokesman Ted Pile told The Register-Herald that the seals are covered with fill dirt.
The mine hasn’t operated since the explosion on April 5, 2010. It was the worst U.S. mine disaster in four decades.
Virginia-based Alpha acquired the mine in Montcoal last summer when it bought Massey Energy.
Alpha announced earlier this year that it would seal the mine.
