Rescuers are pumping out water in the quest to free 11 coal miners trapped in a flooded colliery in northwest China's Shaanxi Province, authorities said Tuesday.
Five pumps are working around the clock.
As of 9 a.m. Tuesday, 25 hours after the flood, around 4,600 cubic meters of water had been taken from the Zhaojin mine in the city of Tongchuan, lowering the water level by 113 cm.
Sixty-seven workers were underground when the flood occurred: Fifty-six managed to escape.
The cause of the accident is still not known.
