Seven people remain trapped underground following a coal mine accident in Southwest China's Yunnan province, local authorities said Tuesday.
A total of 10 people, including the coal mine's manager, a safety inspector and eight workers, became trapped after a coal mine shaft caved in Monday afternoon at a coal mine in Luxi County, a government spokesman said.
Three people were rescued as of 9 am Tuesday, the spokesman said.
The 10 people were inspecting the mine's ventilation facilities when the accident occurred, he said.
