Wu Dengfan, a 40-year-old farmer from Gulang county in Gansu who worked at a gold mine close to the Mongolian border from 1996 to 2006, had a similar experience.“We even preferred not to wear masks inside the mine, because it made breathing even more difficult,” said Wu, who has stage II pneumoconiosis. “When we finished our work and came out of the mine, each of us was completely covered in dust.”
