WARSAW, March 20 (Xinhua) -- Some 19 miners were rescued from a Polish copper mine after being trapped underground by a cave-in, a spokesman of the mine operator said Wednesday.
The miners were trapped 600 meters below ground at the Rudna mine, about 400 km southwest of the Polish capital, when an earthquake triggered a collapse in the mine late Tuesday night, KGHM spokesman Dariusz Wyborski said.
There had been no contact with them for two hours as the tremor cut communication lines, the spokesman said.
The rescuers reached the miners after tunneling through huge rocks, he added.
The mine, which has been in operation since 1974, is in the Silesia region, near Poland's borders with Germany and the Czech Republic.
