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.
