Surface mining - Wikipedia

Surface mining - Wikipedia

Surface mining, including strip mining, open-pit mining and mountaintop removal mining, is a broad category of mining in which soil and rock overlying the mineral deposit (the overburden) are removed, in contrast to underground mining, in which the overlying rock is left in place, and the mineral is removed through shafts or tunnels.. Surface mining began in the mid-16th century [dubious .
