GUIYANG - Seven miners who had been trapped in a flooded coal mine were confirmed to be dead in Southwest China's Guizhou province, authorities said Sunday.

Rescue work completed on Sunday evening, ten days after the accident happened at the Dachong Coal Mine in Changtian township, Huishui county, said a spokesman with the Huishui County Committee of the Communist Party of China (CPC).

Relevant responsible officials, including head and CPC secretary of the township and chief of the county's work safety supervision bureau, were sacked or suspended from duty for investigation.

The flooding occurred around 1:30 pm on October 11 when 33 miners were working underground. Twenty-six managed to escape, and seven others were submerged by water.

The licensed mine has an annual production capacity of 90,000 tonnes.

Further investigation is underway.
