POLKOWICE, Poland -- Nineteen miners were pulled alive and well from a copper mine in southern Poland on Wednesday after a small earthquake trapped them almost 2,000 feet below the surface late Tuesday.

It took seven hours to tunnel through collapsed rock to reach the miners, who were working at the Rudna copper mine in southern Poland when a small tremor trapped them there at 10:09 p.m. local time (5:09 p.m. ET) on Tuesday.

Families react to the news Wednesday that 19 miners were rescued after a small earthquake trapped them some 2,000 feet below the surface at the Rudna copper mine in southern Poland.

Two were treated for minor injuries, while the others, shaken up and covered with grime after a grueling night, were on their way home.

Families of the miners, who gathered near the site, cheered when the mine's operator, KGHM, announced that all 19 were alive and were slowly being taken out through a hole dug by the rescuers.

"This was the biggest accident in KGHM history," chief executive Herbert Wirth told Reuters. "Never in our history has it happened that 19 miners were trapped with no contact."

The Rudna mine is about 250 miles southwest of the Polish capital, Warsaw.

After the quake on Tuesday, workers on the surface lost contact for several hours with the trapped miners because communication lines into the shafts had been severed.

The mine is in the Silesia region, near Poland's borders with Germany and the Czech Republic. It has been in operation since 1974. State-controlled KGHM is Europe's second-biggest copper producer.

Poland has large numbers of mines, mostly in the heavily industrialized Silesia region. In 2006, a gas explosion at a coal mine in the region killed 23 miners.
