The owner of the mine was on Fox News. He denied they are using the collapsed ceiling method. He said Union officials were wildly speculating (in an effort to unionize the mines in Utah) and the MSM ran with the story. There is plenty of hope for those miners.
Well, the TV showed graphics that said they WERE doing it that way.
(Who to believe? ;^)
HOPE indeed then!!! MIRACLES even!
My buddy in the sound booth at church worked in a limestone mine. They have 'streets' and 'avenues' cut in the limestone, with columns of rock left that support the overburden.
It seems as they get about 3/4 of the material this way.
Our previous Pastor and his dad used to work in a coal mine on the ILL/IND border. It was a below ground one, not an open pit like the ones mostly in IND.
