The death toll from a rock burst at a coal mine in east China's Shandong Province stood at 21 as the last two miners were confirmed dead on Monday, ending the nine-day rescue operation, local authorities announced.
The last two people trapped underground for days were found dead on Monday afternoon.
Among the 22 miners trapped after the incident, only one survived.
They were trapped in the tunnel after coal fell at both ends of their shaft from a rock burst at Longyun Coal Mining Co. Ltd. in Yuncheng County on October 20.
Rock bursts are often caused by fractures in rocks due to mining.
