Chilean rescue workers say they have finished drilling an escape shaft for 33 miners trapped for over two months half a mile underground after a cave-in, setting the stage for their evacuation in a world record survival story.
Engineers must now decide how much of the inside of the shaft to line with metal tubing before starting to hoist the men one at a time to the surface in special capsules, a task the government says will take from three to 10 days.
