The 2010 Copiapó mining accident, also known then as the "Chilean mining accident", began on Thursday, 5 August 2010 with a cave-in at the San José copper–gold mine, located in the Atacama Desert 45 kilometers (28 mi) north of the regional capital of Copiapó, in northern Chile. Thirty-three men, trapped 700 meters (2,300 ft) underground and 5 kilometers (3 mi) from the mine's entrance via spiraling underground ramps, were rescued after 69 days.
