Beijing: A sudden burst of gas inside a coal mine in China’s central province of Hunan killed at least seven miners Sunday, officials said.
A total of 39 miners managed to escape after the accident at the Xiangzhong coal mine in Lianyuan city, Xinhua reported.
Workers engaged in drilling work triggered the gas burst, a probe showed.
