Nineteen miners have been confirmed dead in east China following a mining accident earlier this month that trapped 22 people, state media reported on Monday.
The tunnel where the miners were working was blocked at both ends by coal after pressure caused rocks to fracture and break on October 20, the official Xinhua news agency said. Only one miner has been rescued so far.
Rescuers working to clear the tunnel recovered six bodies on Sunday.
Two miners remained unaccounted for as of Monday morning. The accident took place at a mine owned by Longyun Coal Mining Co. Ltd. in Shandong province.
In December 2016, explosions in two separate coal mines in the Inner Mongolia region and in northeastern Heilongjiang province killed at least 59 people.
