XIANGNING, China - Rescuers pumped water Wednesday in a fading bid to find more survivors in a flooded mine in northern China where earlier 115 miners had been pulled to safety in dramatic rescues after being trapped for more than a week. A seventh body was recovered Wednesday but 31 miners are believed trapped in two areas and there have been no further signs of life. "Now we're racing against time and putting efforts in full swing to concentrate on these two areas," Liu Dezheng, the rescue headquarters' spokesman told a news conference. "There are 31 workers there, holding on, waiting for us to rescue them " we must face the work ahead with this in mind," Liu said. With 5,000 rescuers on the mine site, pumping water out was the top priority."It's only after we've pumped water out and cleared a way through that we can go in. If we can't go in, we can't rescue them," he said. "At the moment we have not had any contact with them," he said of the trapped miners. Liu said there was also the threat of dangerous gases seeping into the spaces underground that could sicken rescuers or cause an explosion. The lowered hopes come after Monday's dramatic rescues at the Wangjialing mine in Shanxi province. The 115 miners survived for eight days underground by eating sawdust, tree bark, paper and even coal. Some strapped themselves to the walls of the shafts with their belts to avoid drowning while they slept. State media reported Wednesday none of the survivors were in serious condition, and that more of them were eating solid food. One of the miners, Su Zexi, told Central China Television that quick thinking by a team leader saved some of the miners. "Our team leader Wang Jiming realized that the tunnel had a dead end. When the water started to rise, he cracked the tunnel open, and the water flowed away through the tunnel," said Su from his hospital bed, with an oxygen line hooked up to his nose. "Then we got through and met another 50 miners from the other side. He and some other experienced older miners somehow found us a dry, warm place with enough air."
