BREAKING!!! EARTHQUAKE Traps 18 Polish workers in Underground Mine
""There was a quake in the Rudna mine," Wyborski said. "The rescue operation is difficult because huge amounts of rocks have to be removed."
There was no contact with the trapped miners because the tremor cut communication lines, the company said.
The mine is in the Silesia region, near Poland's borders with Germany and the Czech Republic. It has been in operation since 1974. The operator, state-controlled KGHM, is Europe's second-biggest copper producer."
