The gypsum mine in east China's Shandong province collapsed on Christmas Day, killing one and leaving 17 miners missing, including the four survivors, who were lifted to safety today after spending 36 days trapped inside the mine.
State-run CCTV showed dramatic footage of a miner being lifted to the surface and then taken to the hospital. Eleven miners had been rescued earlier.
Over 400 rescue and emergency workers participated in the operation spread over a month. The workers tunnelled down the collapsed mine, slowly, so that the mine does not cave in completely.
The company chairman Ma Congbo, committed suicide a few days after the accident by throwing himself into the mine well.
