Mining Underground mining Britannica

Mining Mining Underground mining: When any ore body lies a considerable distance below the surface, the amount of waste that has to be removed in order to uncover the ore through surface mining becomes prohibitive, and underground techniques must be considered. Counting against underground mining are the costs, which, for each ton of material mined, are much higher underground than on

Rockwell Automation drives Underground Mining

Three miles underground, a sophisticated, high-powered mining machine moves steadily through a six-foot-high tunnel at an average speed of two miles per hour, carving out coal, then conveying it to a crusher and carrying it to the surface. Instead of digging out the ore, a long-wall mining system slices it from the exposed tunnel face, using giant rotating shears. The shorn coal tumbles onto a
