WARSAW (Reuters) - Rescuers battled in the early hours of Sunday to reach four coal miners who remained trapped nearly one kilometre (0.6 mile) underground in southern Poland after an earthquake.
The 3.4 magnitude quake hit the Borynia-Zofiowka-Jastrzebie mine on Saturday morning, initially trapping seven miners at a depth of about 900 metres (2,950 feet), state mining office WUG said.
Two had been rescued by mid-afternoon, and one was found late on Saturday but showed no signs of life, the deputy chief executive of the mine owner JSW, Tomasz Sledz, told reporters.
He said the third miner was buried and that it was not yet possible for rescuers to confirm he was dead. He said there had been no contact with the remaining four miners.
The two rescued miners were taken to a hospital in Jastrzebie-Zdroj city in “relatively good condition” and could walk unaided, JSW Chief Executive Daniel Ozon told reporters.
“We are doing all we can to save the miners,” Ozon said.
There were about 250 people working in the mine at the time of the quake, JSW said. The missing miners were from a team of 11 that was drilling a new tunnel. Four escaped by themselves.
The 200-person rescue operation was earlier hampered by high levels of methane, which reached a concentration of up to 58 percent.
A spokeswoman for JSW, the European Union’s largest coking coal producer, said earlier that the quake had damaged communications lines in the area.
Prime Minister Mateusz Morawiecki, who reached the mine on Saturday evening, said the rescue operation was very difficult and that he hoped the remaining miners would be saved.
He also visited the two rescued miners at the Jastrzebie-Zdroj hospital.
WUG said the quake was of a type that can occur in coal mines after the removal of deposits builds up tensions in the rocks.
Polish news agency PAP said family members of the missing miners had gathered at the mine and were being counselled by psychologists.
