Warsaw - A Polish coal miner trapped more than a kilometre underground for 111 hours was brought to the surface alive and well Monday after rescuers freed him from under tons of rubble in the Halemba mine in Ruda Slaska, southern Poland....Rescuers located the man thanks to a special transmitter worn by miners.

Zbigniew Nowak, 30, reportedly suffered dehydration but nothing worse. One other miner was rescued shortly after the roof fall and 30 more escaped on their own.
