  • Open-pit mining - Wikipedia

    Open-pit, open-cast or open cut mining is a surface mining technique of extracting rock or minerals from the earth by their removal from an open pit or borrow.. This form of mining differs from extractive methods that require tunnelling into the earth, such as long wall mining.Open-pit mines are used when deposits of commercially useful ore or rocks are found near the surface.

    AdvantagesIssuesTypesUsageCostTechnologyOperationConstructionServiceEarly historyOther factors influencing the choice between open-pit and underground methods may be inferred from the advantages and disadvantages of open-pit mining, some of which are listed below. In specific instances consideration of these may affect the choice of method or result in revision of pit limits established by cost estimates based upon stripping-ore ratios. Among the advantages of open-pit mining are its flexibility, the ability to obtain mass production with it, and the ease with which rate of production

  • Basics of an open pit mine

    In a open pit coal mine, the pit bottom would be the bottom mined coal seam elevation, since it is usually feasible to extract multiple seams when surface mining coal. In a hard rock mine, the bottom of the pit would be the lowest level (elevation) that mining would be conducted on the ore being mined.

  • Open pit copper mining - MAXAM

    Open-pit mining is used when the orebodies are extensive and relatively close to the surface. The sterile/ore ratio is one of the factors which defines the exploitation method and the final dimensions of the mine cuts. In general, open-pit mining consists of a system to exploit open pits with multiple benches. Operations start with drilling and ...
