Rescue plans for 2010 Copiapó mining accident Rescue plans for 2010 Copiapó mining accident The 2010 Copiapó mining accident began as a cave-in on 5 August 2010 at the San José copper-gold mine in the Atacama Desert near Copiapó, Chile. The accident left 33 men trapped below ground who survived underground for a record 69 days. All 33 men were rescued and brought to the surface on 13 October 2010 over a period of almost 24 hours. After the last trapped miner was winched to the surface, the rescue workers still underground held up a sign before the camera stating """" (English: ""Mission accomplished Chile"") to the
Ontario Mine Rescue to allow for a four-hour capability. The BG174 proved a workhorse for almost 40 years before it was replaced by the BG4. Ontario Mine Rescue took on added responsibility in 1984 after four miners were trapped and killed in a rockburst at Falconbridge No. 5 Shaft near Sudbury. The Stevenson Commission recommended that the organization's mandate be expanded to conduct training in and respond to non-fire emergencies. Training on non-fire rescue equipment began shortly after. In January 2001, responsibility for Ontario Mine Rescue was transferred to the Mines and Aggregates Safety and Health Association, now a part of Workplace Safety
