At least seven miners are missing and one has died after an earthquake occurred at the Rudna mine in Polkowice in southwestern Poland, state news agency PAP has reported.
An earthquake of magnitude 4.4 struck at 9.09pm on Tuesday (local time), according to the US Geological Survey.
It said the quake was very shallow, only 10km deep, which would have magnified its effect at the mine belonging to state-run copper producer KGHM.
According to Polish state authorities, quoted by PAP, the quake's epicentre was located 1500 metres underground.
"There were 16 people in the danger zone. Some of them were walked out," a spokeswoman for the company was quoted as saying by private radio RMF FM.
The one miner who died was among nine people evacuated, according to media reports.
Three miners who were injured the most are in hospital with back and head injuries. Their conditions were stable, according to RMF FM.
