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 and is practiced throughout the world, although the major

Figure 2 shows a comparison of the annual produ ction rates and producti vities of US coal mines. Surface mines have very few limitations on the operation of large machines with high capacity, whereas underground operations are considerably restricted by narrow working spaces and rock conditions. Moreover, less commuting time is required at a

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.
