Polish miner killed in cave-in, three injured

WARSAW, Feb 22 (Reuters) A Polish miner was killed and three others injured yesterday when a mine shaft collapsed in southwest Poland, Polish metal's group KGHM said today.

Minor earth tremors triggered a slide 950 metres below the surface at the group's biggest mine late last night in the town of Rudna, 300 km from Warsaw.

Rescue teams worked through the night to rescue two workers with minor injuries and the body of a 35-year-old miner who was killed, a company spokesman said.

A fourth critically injured miner was taken to hospital.

A total of 30 workers were evacuated. The mine stayed opened and production continued.

State-controlled KGHM is the world's sixth biggest copper producer and one of Poland's biggest companies.

In November, 23 coal miners at a different company died in a gas explosion in Poland's worst mining disaster since the 1970s.
