Opencast mining

2003-3-12 · Opencast mining, also called "opencut mining," or "open pit mining," is based on the principle of continuous conveying, employing large earth-moving machinery such as the Big Muskie walking dragline to mine the coal, iron ore or phosphates at the surface rather than underground. Opencast mining may include multi-seam mining, where two or more coal seams are excavated.
