All 10 miners who were trapped underground after a tunnel collapsed in the Daanshan coal mine outside Beijing have been rescued, official media reports said yesterday. The miners, who had been trapped for more than 100 hours, were found yesterday morning, Xinhua said. They were immediately sent to hospital for treatment. 'Wearing oxygen masks, all 10 miners were carried to ambulances one by one on stretchers and taken away,' China News Service reported. Xinhua said Beijing Party Secretary Liu Qi visited the mine yesterday and thanked the rescuers for their efforts. However, it did not say if the miners were injured and give no details of their conditions. Officials earlier said rescue efforts had been hampered by the complex rock structure above the collapsed tunnel. Rescuers pumped oxygen into the tunnel to keep the miners alive. The tunnel collapsed on Sunday morning. Although rescuers had heard noises from the tunnel, they were not sure about the condition of the miners and their chances of survival. The Daanshan coal mine is a state-run enterprise employing more than 2,000 workers. Despite the accident, officials maintained Daanshan had a good safety record and this week's accident was its worst in 10 years. Xinhua said eight of the 10 miners came from Sichuan province . Although they are not local residents, they had signed proper labour contracts with the mine company and were insured. Although the accident only involved 10 miners, it attracted the attention of top leaders. Xinhua said Vice-Premier Huang Ju had instructed officials to spare no efforts to save the workers. Separately, Xinhua yesterday reported that 10 miners were killed on Wednesday when a gas explosion destroyed a coal mine in Liupanshui, Guizhou province . It said rescuers found the bodies of five miners yesterday and were still looking for the other five. Thirteen miners were working underground when the explosion happened and only three escaped. Xinhua said each victim's family would receive 66,000 yuan in compensation.
