2010 Copiapó mining accident San Jose Mine were around 20% higher than at other Chilean mines due to its poor safety record. The collapse occurred at 14:00 CLT on 5 August 2010. Access to the depths of the mine was by a long helical roadway. A group nearer the entrance escaped, but a second group of 33 men were trapped deep inside. A thick dust cloud caused by the rock fall blinded the miners for as much as six hours. Initially, the trapped miners tried to escape through ventilation shafts, but the ladders required by safety codes were missing. Luis Urzúa, the duty shift
2008 Ukraine coal mine collapse at some time after the collapse. One body was found in the rubble. On June 9, it was announced that 22 more miners, who had been waiting for 30 hours, were rescued by the crews, while 13 remained buried. On June 10, an official said that there was little chance that the 12 remaining miners were alive, as 9 of them were riding up an elevator when the blast happened, sending the cage down the shaft, and the other 3 were underground, where methane levels were dangerously high after the explosion. Officials were also concerned that the mine could flood.
