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 ...

What is Surface Mining? (with pictures) - Info Bloom

Feb 12, 2021  Quarry mining is one type of surface mining. Strip mining is a form of surface mining that is primarily used for coal excavation. The rock and dirt covering the ore is removed one strip at a time. Once the ore has been taken from the first strip, a second strip is cut next to it, and the waste from the second strip is used to back fill the first.
