BEIJING -- Authorities say 123 workers are trapped in a large flooded coal mine in northern China.
The Xinhua news agency reports that 138 of the 261 miners were able to escape as underground water began flooding the mine.
The Xiangning county mine covers an area of 180 square kilometers and is undergoing construction. When the repairs are finished, the mine will be able to produce six millions tons of coal each year.
China's coal mines are among the most dangerous in the world, with safety standards often ignored.
