A coal mine flooded on Saturday at the Hengxinyuan Coal Mine in Jixi City.

24 miners remain trapped.

China's coal-mining industry is the deadliest in the world, with thousands killed every year in floods, explosions, collapses and other accidents.

Higher wages in the mines tempt workers.

So far two mine officials have been sacked for dereliction of duty and the mine managers are reported to be in custody.
