MELVILLE, W.Va. -- A day after a fire broke out in a West Virginia mine, rescuers still have miles underground to search for two men who didn't get out.
Flare-ups have intermittently hampered the search.
About 20 rescue teams from four states were at the scene Friday night. They were searching for the men in four tunnels -- each about four miles long.
Smoky conditions that have slowed rescue efforts are improving. Ray McKinney, with the Mine Safety Health Administration, said crews are re-channeling ventilation in the mine to get better visibility.
Nineteen other miners were able to reach the surface after the fire broke out. They were waiting for news on the two missing men in a church with relatives -- a scene reminiscent of the one less than three weeks ago near another West Virginia mine, where 12 men died.
That disaster's sole survivor -- Randal McCloy Jr. -- remains hospitalized in a coma.
West Virginia Gov. Joe Manchin met with the families in Melville. He described them as hopeful, but, "They know that the odds are a little bit long."
Friday morning, two rescue teams reached the site of the fire, which started on a conveyor belt more than 10,000 feet inside the mine, but they weren't able to continue because the smoke was too thick. So, they turned their attention to putting out the fire.
Offiicals had originally said they would let the fire burn itself out.
Twelve miners had gone into the mine to start their shift on Thursday when a carbon monoxide monitor sounded an alarm. About 10 minutes later, the company told the miners to leave. They ran into smoke as they left.
Two of the 12 were separated from the group. In addition to the 10 who escaped, nine others in another part of the mine were also able to get to safety.
