In 2010, folks in every single place had been riveted to the story of the 33 miners in Chile trapped 2,300 ft (seven-hundred meters) beneath the Earth's surface in a copper and gold mine. The miners spent more than two months there, getting meals, air and letters from beloved ones through bore hills drilled to their location in a protected workroom. Meanwhile, the bigger-scale drilling of an escape shaft made gradual progress. Finally, on Day 69, rescuers lifted every of the miners out alive. The saga reminded the non-mining world of a often invisible reality. Deep beneath the floor of the Earth lie some of essentially the most frightening factories on the earth: underground mines. An underground coal mine can drive 2,500 feet (750 meters) into the Earth and different types even deeper -- uranium mines can attain 6,500 ft, or 2 kilometers. Mining sites have modified rather a lot from the images we now have of the 19th century when men with shovels toted canaries to make sure the air underground was not toxic.
