Seven workers were believed trapped underground a flooded coal mine in east China's Jiangxi Province Tuesday, a local work safety official said.

The accident occurred at about midday in a pit in Jinshan town in Shangli county, said the official in Shangli, who declined to be named.

The trapped miners still had a good chance of survival, he said.

Further details are not immediately known.

In a separate coal mine accident, five miners died and seven are trapped after a gas leak in Jianshan town in Gaoan city in Jiangxi early Tuesday. Rescuers said the chances of survival were slim because of the gas accumulation in the shaft.
