Prime Minister Mateusz Morawiecki, who came to Jastrzebie Zdroj on Saturday night, visited the hospitalized miners and met with their families.
After the quake hit, four miners were rescued quickly but seven others went missing.
Rescuers attained yet another miner on the list of 11 who were immobilized after a 3.4-magnitude natural disaster struck on a coalmine in southern Poland, but he had been unresponsive. He said there had been no contact with the remaining four miners. Two were rescued earlier with injuries that were not life-threatening.
More than 200 rescuers and support teams were working through the rubble and pumping air to the search area to find the missing miners, Ozon said.
Two miners were found dead Sunday and three others remain missing some 900 meters (2,950 feet) below ground since the quake hit Saturday morning in the mine, located in the town of Jastrzebie-Zdroj, close to Poland's border with the Czech Republic. It was not clear if the miner was dead or alive. He says the miner had been trapped under some metal and was not responsive.
Prime Minister Mateusz Morawiecki, who reached the mine on Saturday evening, said the rescue operation was hard and that he hoped the remaining miners would be saved.
