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.
For coal mines across the globe, StrataConnect Wireless communications and tracking is the ideal system. It truly is wireless and battery-powered - from surface operations to underground, and the entire system is intrinsically safe. Mines can continue connectivity all the way to the face.
