Chilean miners trapped after mine collapse; miscalculated drilling delays rescue

August 11, 2010 A gold mine collapse in Copiapó, Atacama Region, Chile has trapped 33 miners since last Thursday. Another collapse occurred on Saturday, that provoked temporary suspension of the rescue works.

Rescue efforts were first focused on a ventilation shaft, but attempts to reach the miners failed. Rescuers have been drilling into the mine since Sunday. "The situation is very complex, the mine continues to have collapses because there is a geological fault-line," said Sebastián Piñera, President of Chile, who "pledged to do everything possible to get to the trapped miners," but acknowledged he was pessimistic.

There is no certainty that the miners, who are trapped about 400 meters (1300 feet) below the ground, are still alive.
