Openpit mining, also known as opencast or opencut mining and in larger contexts megamining, [1] is a surface mining technique of extracting rock or minerals from the earth from an openair pit, sometimes known as a borrow . This form of mining differs from extractive methods that require tunnelling into the earth, such as long wall mining.

Story | 31 Jul, 2019. Casenote: Gloucester Resources Limited v. Minister for Planning. By Rob Fowler For the first time, a proposed opencut coal mine has been rejected by a court in Australia on environmental grounds that include the projected carbon emissions that would arise from its operation and from the downstream burning of its coal.
Opencut mining or surface mining is a technique used to extract ore located close to the surface and is the most common method of mining. Opencut mines are used when deposits of commercially useful minerals or rock are found near the surface and where the overburden (surface material covering the valuable deposit) is relatively thin or structurally unsuitable for tunneling.

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.

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.

Opencut coal mining. Opencut (often called opencast outside Australia) mining usually occurs where the coal deposit is close to to the surface. ... fine coal cleaning and process control, and strata reinforcement technology. There are more than 550 Australian mining equipment and technology suppliers including world leading mining brands.
Overall when compared to other methods, opencut is much safer. Opencut mining is responsible for 65 percent of the raw coal production in New South Wales. Opencut is also a good method for gold and copper. Underground mining. Underground mining occurs underground through the creation of tunnels. These tunnels go deep into the mineral seam.
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 ratio a measure of an opencut mine's implicit efficiency represents the amount of overlying rock that has to be removed to expose the coal seam available for coal mining. Data from NSW Coal Services has shown a clear trend to increasing strip ratios. Strip ratios have risen at a rate of 6% per year on average in NSW since 2021.
Samples were collected from an opencut coal mine in Inner Mongolia with a total length of km. The major coal seams are nos. 19 and 21 with a current mining rate of 360 m/a.
