Beijing, Dec 16 : At least seven workers were killed and three others injured in an accident at a coal mine in southwestern China, state media reported on Sunday.
The accident took place on Saturday in Chongqing municipality when the connecting segment of a mining skip broke, causing it to slide down the inclined shaft, state-run Xinhua news agency reported.
Seven miners working in the shaft were killed. The three injured miners have been rushed to a hospital, the report said.
Accidents in coal mines are common in China. However, the number of deaths have reduced at mines in recent years.
In October, 8 miners were killed after a rock burst ripped through a coal mine in Yuncheng county of Shangdong province.
In June, a powerful explosion in an iron mine in country's northeast Liaoning province claimed the lives of 11 workers and left nine others injured.
Similarly in May, a methane gas explosion ripped through a coal mine in central China's Hunan province, killing at least five workers.
