Openpit mining, also known as opencast mining, is a surface mining technique that extracts minerals from an open pit in the ground. Openpit mining is the most common method used throughout the world for mineral mining and does not require extractive methods or tunnels.
The strip mining process is suitable for fairly flat, shallow, singleseam coal, lignite, and other bedded deposits. The mineral layer is covered by an even thickness of overburden composed of soft top soil and weathered rocks in succession. The soft and unconsolidated overburden can be stripped and removed by dragline or shovel to expose a

area strip mining type of surface mining used where the terrain is flat. an earthmover strips away the overburden, and a power shovel digs a cut to remove the mineral deposit. The trench is then filed with overburden and a new cut is made parallel to the previous one
Strip mining is a mineralextraction process in which a layer or seam of undesired material (called overburden) is removed from the surface of an area to allow efficient access to a desired material existing underneath the layer being stripped.
25/2/2015#0183;#32;2. Strip Mining Is Faster Most other mining techniques require the digging of tunnels, which adds additional time to the process. Strip mining does not rely on the digging of tunnels and since the route to the surface is much shorter, this also cuts down on the amount of time spent.

23/6/2017#0183;#32;Strip Mining. Strip mining is the process of removing a thin strip of overburden (earth or soil) above a desired deposit, dumping the removed overburden behind the deposit, extracting the desired deposit, creating a second, parallel strip in the same manner, and depositing the waste materials from that second (new) strip onto the first strip.

This means that surface mining destroys mountain tops, landscapes, forests and wildlife habitats.

Strip mining is commonly used for mining coal seams and phosphate beds. In hilly terrain the mining of the overburden and the deposit (usually a coal seam) follows the contour around the hill and into the hillside up to the economic limits; hence it is called contour mining. Unexpected geological conditions during the mining process can
