The 2010 Copiapó mining accident, also known then as the “Chilean mining accident”, began in the afternoon of Thursday, 5 August 2010 as a significant cave-in at the troubled 121-year-old San José copper–gold mine. The mine is located deep in the Atacama Desert, one of the driest and harshest regions on earth, about 45 kilometers (28 mi) north of the regional capital of Copiapó, in northern Chile, South America.[1] The buried men, who became known as “Los 33” (“The 33”), were trapped 700 meters (2,300 ft) underground and about 5 kilometers (3 mi) from the mine’s entrance via spiraling underground service ramps.
