Rescuers have yet to find any survivors after a landslide early on Friday buried 83 Chinese miners as they slept near the Tibetan capital, Lhasa.
Chinese state-run media say 1,000 police, firefighters and doctors have been sent to the disaster site.
The miners' camp was destroyed by thousands of tonnes of rock. The BBC's John Sudworth reports from Shanghai.
