HOLMES MILL, Ky. (AP) - Kentucky's governor says relatives of five miners killed in an early-morning accident want answers.
He says knowing more about what caused Saturday's explosion will "help them deal with it a little more."
A sixth man, who was closer to the mine's exit than his co-workers, survived.
The wife of one of the dead miners says her husband leaves
behind two teenage daughters.
She says Roy Middleton had thought about quitting the mines, but needed the job to support his family.
Another miner who died came from a family of miners. As a relative put it, "Mining is all he's ever done."
Ten Kentucky miners have been killed on the job this year. That's more than in all of last year.
An investigation into Saturday's blast is under way.
