So how bad will this story become?

Already about as bad as can be:

Rescue teams planned to search again for four workers missing in a coal mine where a massive explosion killed 25 in the worst U.S. mining disaster in more than two decades, though officials said Tuesday that the chances were slim that the miners survived.

And not surprisingly:

Though the cause of the blast was not known, the operation run by Massey subsidiary Performance Coal Co. has a history of violations for not properly ventilating highly combustible methane gas, safety officials said.
