Over a month ago, on August 5, 2010, the roof of the San Jose copper and gold mine collapsed, trapping 33 miners inside, 700 meters (2,300 ft) below ground near Copiapo, Chile. The fate of the miners was not immediately known - it took 17 days before a drill reached their refuge, discovering them alive and well. Rescue work began immediately, but even with several concurrent plans underway, the quickest likely rescue will still take two to three months. Until then, the 33 men will have to endure high temperatures and humidity in isolated conditions. A video link has been established, many relatives have set up camp nearby, and food, air, messages and supplies are delivered by several narrow boreholes. Fluorescent lights with timers are to be sent down to attempt to keep the men on a normal schedule by imitating day and night as they care for each other and assist in their own rescue. Once it reaches them, the diameter of the rescue borehole will be very narrow. so each miner will have to ensure they have a waistline of no more than 90 cm (35 in) to escape. ( 42 photos total
