Drilling to reach trapped Chilean miners beginsCopiapo, Chile (CNN) August 31, 2010
Drilling has begun as part of an effort to reach the 33 miners who have been trapped underground in Chile for more than three weeks, authorities said Tuesday.
The effort to drill through more than 2,300 feet (700 meters) of rock and safely extract the workers could take three to four months, officials said. The hole currently underway is the excavation hole, where the drill bit will be placed.
