    What Is Underground Mining? (with Pictures)

    underground mining is a technique used to access ores and valuable minerals in the ground by digging into the ground to extract them. this is in contrast with techniques like open pit mining, in which the surface layers of ground are scooped away to access deposits, or mountaintop removal, in which the top of a mountain is simply shaved off to access the ore inside.
