Upper Big Branch Mine Permanently Sealed

{Montcoal, West Virginia}...The Upper Big Branch Mine hasn't operated since the April 2010 explosion that killed 29 workers. Wednesday, Alpha Natural Resources put a final concrete seal in place at the mine, closing the mine for good. It sealed the mine's portals, which are large tunnels used by miners to get underground. Alpha will complete all activities at the mine within the next few weeks.
