BEIJING (AFP) - Ten miners have been killed in an accident in a coal mine in northwest China, state media said Saturday, a week after an explosion killed 45 miners in another part of the country. The Xinhua news agency said the accident occurred at the Huacaoton Coal Mine in Shandan County of Gansu Province on Thursday evening, with the last body pulled from the mine early Saturday, according to a safety official. The 10 workers fell off a platform when it overturned more than 200 metres (yards) above the bottom of the mine’s shaft, which was flooded with water, the agency said. Accidents in China’s mines occur frequently.
