  • Basics of an open pit mine

    The planning of an open pit mine is, therefore, basically an exercise in economics, constrained by certain geologic and mining engineering aspects A bench may be defined as a ledge that forms a single level of operation above which mineral or waste materials are mined back to a bench face...

  • Surface mining

    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...

  • Hydrology of reclaimed opencast coal

    Abstract The success or failure of a land reclamation project is to a considerable extent determined by the management of surface runoff and drainage Reclaimed overburden tends to allow little infiltration because of compaction during reclamation, subsidence, and the accelerated weathering of coal shal This rapid production of fine sediment also tends to make subsurface drainage difficult ....

  • Opencast Mining

    Opencast Mining Opencast mining is the most common method used throughout the world for extracting minerals (Ha et al, 2011) and commonly produces much waste, due to the removal of large volumes of materials (Anawar et al, 2013; Bini, 2012) From: Assessment, Restoration and Reclamation of Mining Influenced Soils, 2017 Related terms: Coal Mine...

  • Environmental Consequences of Open Pit Mining

    Environmental Consequences of Open Pit Mining An open pit mine is a type of excavation where surface and subsurface materials (soil and rock) are removed, typically through use of explosives and mechanical mining and hauling equipment, to gain access to commercially valuable ores or other buried natural resources, including coal and gemstones ....
