Rescuers expand lifeline to trapped Chile miners

COPIAPO, Chile — Engineers reinforced a lifeline Monday to 33 miners entombed deep inside a Chilean gold and copper mine, preparing to keep them supplied with food, water, medicine and communications during the four months it may take to carve a tunnel wide enough to pull them out. A team of doctors and psychiatric experts also arrived Monday at the remote mine, implementing a plan to maintain the miners’ sanity as well.
