Coal mining by opencut methods. A dragline is used to remove overburden from a gently dipping coal seam, placing it in spoil piles on the updip side (left). A pattern of blast holes has been drilled into the overburden on the right of the image. The coal is removed by a power shovel and placed into trucks for haulage from the mine.

Abstract Open pit mining method is one of the surface mining methods that has a traditional coneshaped excavation and is usually employed to exploit a nearsurface, nonselective and lowgrade zones deposits. It often results in high productivity and requires large capital investments, low operating costs, and good safety conditions.

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 list of commodities is extensive, although the relative proportions mined underground and on the surface vary from mineral to mineral. Massive tonnages of hard coal and lignite are also produced from surface mines, although the terminology used open cast or open cut, rather than openpit indicates that the technology and engineering concepts used are often markedly different from ...

1. Introduction. Opencut mining causes complete disruption of landforms and soils, which can impede or prevent the restoration of original or other preexisting ecosystems because ".essential properties of the original soils cannot immediately or easily be reinstated" (Ngugi et al., 2018, p. 839).However, the postmining outcome should also be contingent on preexisting landuse.

Mining Strip, OpenPit, Quarrying: It has been estimated that more than twothirds of the world's yearly mineral production is extracted by surface mining. There are several types of surface mining, but the three most common are openpit mining, strip mining, and quarrying. These differ from one another in the mine geometries created, the techniques used, and the minerals produced.

The openpit method is generally practiced where thick coal seams are overlain by thick or thin overburden; it is also used for mining steeply pitching coal seams. In the beginning stages of mining, considerable volumes of overburden materials must be accumulated in large dump areas outside the mine. Auger mining

The decision on whether to operate an above or underground mine is heavily influenced by a couple of important factors. The major factor in deciding on whether to go underground or open cut is the stripping ratio (Whittles et al. 2007).This is defined as the ratio of the volume of overburden (BCM) moved to the amount of coal produced (tonnes).
