Underground mines are the alternative to surface mines. Surface mines excavate from the top down, a method that can become inefficient at depths greater than about 200 feet 60 meters sources Illinois Coal Association, De Beers. Undergrounds coal mines can drive 2,500 feet 750 meters into the Earth and other types even deeper -- uranium mines can reach 6,500 feet, or 2 kilometers. But those depths are extreme most top or bottom out at about 1,000 feet 300 meters sources Times Wire, ARMZ, Illinois Coal Association.
Mining has changed a lot from the images we have of the 19th century when men with shovels toted canaries to make sure the air underground was not toxic. Modern mines feature extensive ventilation and water-drainage systems, high-tech communication networks and increasingly computerized machines that reduce the number of humans required underground.
All underground mines have some crucial components in common ventilation shafts to clear toxic fumes from drilling and blasting escape routes access shafts to lower workers and equipment ore-transport tunnels recovery shafts to carry excavated ore to the surface and communication systems to send information back and forth between the surface and the depths source Hamrin.
No two mines are alike, though. Technology applications and basic decisions about design and mining method rest on considerations like the type of ore being mined, composition of surrounding rock, shape and orientation of the ore deposit, geologic features underground, and simple economics source United Mine Workers of America.
