FUNING, Yunnan, July 20 (Xinhua) -- Fourteen workers rescued from a collapsed tunnel early Sunday are "in pretty good condition", said their doctors in the southwestern province of Yunnan.
The workers were saved at around 3 a.m., after being trapped for 131 hours in the debris of a collapsed railway tunnel in Funing County.
A thorough checkup showed they were in pretty good condition, said Zhang Jinlong, vice president of the People's Hospital in Funing County.
"Four of them had low potassium, as a result of unbalanced diet and particularly lack of vegetables," said Zhang. "They will recuperate soon after a few days of normal diet."
Xinhua reporters saw the workers were either sleeping or playing with cell phones in their hospital beds. Some were chatting with friends.
Zhang said they would spend Sunday night in hospital and if all was well, they were expected to be discharged Monday morning.
About 20 meters of a 13.5-km tunnel, known as Funing No. 1 tunnel, collapsed at 4 p.m. Monday, in Funing County of Zhuang and Miao Autonomous Prefecture of Wenshan, trapping 15 workers. More than 400 rescuers were mobilized to save the trapped men.
Rescuers drilled a hole in the collapsed tunnel Tuesday and managed to send food, water and flashlights to the workers.
Rescue work continued Sunday for the last missing worker.
The tunnel was on a pivotal railway linking Yunnan with south China's Guangxi Zhuang Autonomous Region.
