Polish rescue teams were digging through a vast copper mine late Tuesday searching for a missing miner after pulling out several of his colleagues following a tremor at the site, operator KGHM said.
The company had initially put the number at 14 missing miners out of the 32 people who had been in the danger zone around the Rudna mine in south-west Poland, after the tremor struck some 770 metres (2,526 feet) underground around lunchtime.
"A rescue operation is underway to locate the last miner at Rudna. Two people are in the hospital," the company said on Twitter.
KGHM spokeswoman Lidia Marcinkowska-Bartkowiak told reporters that the two hospitalised miners "most likely have broken legs."
"Eleven people are undergoing medical checkups. No one is seriously injured," she added, quoted by the Polish news agency PAP.
According to the US Geological Survey, a magnitude 4.1 quake struck near the southwestern village of Grebocice.
Rudna is Europe's largest copper mine and one of the biggest in the world. It has 11 operating shafts, the deepest of which is 1,25 kilometres (0.77 miles) deep.
In late 2016, a quake at the mine killed eight miners.
