At least 114 survivors have been pulled out of a Chinese coal mine over a week after being trapped by an underground flood.

"It's a miracle," rescue worker Wei Fusheng said. "It's been worth all our efforts. No sleep for several days."

State media broadcasting live from the mine put the number of survivors so far brought above ground at 114.

A total of 153 workers had been trapped in the state-owned Wangjialing mine in Shanxi since it flooded during construction work on March 28.

The accident has been blamed on lax safety standards.

Officials said a search for the remaining 39 miners was continuing.

Television images showed survivors being brought out of the mine pit one after another, strapped to stretchers and wrapped in green blankets.

Towels covered their eyes and blackened faces to protect them from lights after so long underground.

Groups of rescue workers wearing blue and orange jumpsuits loaded them into waiting ambulances.

Hundreds of family members awaiting news of their loved ones stood along the road, bursting into applause when the ambulances passed by.

Many of the survivors were dehydrated, suffering from hypothermia and doctors feared gas poisoning from the bad air in the shaft.

The miners also had skin infections from being in the water so long and some were in shock and had low blood pressure.

At least 3,000 rescuers had been racing against time to pump water out of the mine after it flooded in the latest accident.

According to official statistics, 2,631 coal miners were killed last year in China.
