One miner killed and another nine were trapped underground over 48 hours after part of a coal mine in northeastern China's Liaoning province collapsed on 2: 30 a.m. November 11, National Business Daily reported, citing a statement issued on November 13 from the mine's holding company Liaoning Hongyang Energy Resource Invest.
The coal mine activated emergency rescue and tracked the cause of the accident in the first place. It preliminarily estimated the collapse to be caused by mine earthquake, which is usually incurred by mining activities.
The collapsed coal block, mainly producing coking coal and meager-lean coal, is part of the Hongyang No.3 coal mine, one of five subsidiaries with largest designed capacity and the largest coal mine in Liaoning province.
Hongyang No. 3 coal mine ranked the top with capacity of 4.8 Mtpa in the province in August this year. Its approved production capacity were lifted to 5 Mtpa on December 2013.
There are several coal mine accidents taking place across the country in the month. On November 11, a miner found dead after an electric shock in Linfen, Shanxi; on November 13, two were missing in a flood accident at a coal mine in Jiyuan, Henan.
