The main coal seam of the Zhundong Openpit Coal Mine is a huge inclined coal seam with a thickness of 70 m, and the tendency of the coal seam is to gradually decline from east to west.
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.
In surface mining, the ground covering the coal seam (the overburden) is first removed to expose the coal seam for extraction. The elements of a surface mining operation are (1) topsoil removal and storage for later use, (2) drilling and blasting the strata overlying the coal seam, (3) loading and transporting this fragmented overburden material (called spoil), (4) drilling and blasting the ...
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.
Largescale open cut coal mining operations commenced in Australia in mid 1960s and since then there has been significant developments in this method of mining. The mines are now operating at significantly higher annual tonnages, growing deeper, more complex and operating at higher stripping ratios (Westcott et al., 2009).
30 November 2021 What is Open Cut Mining? Opencut mining is a process of resource extraction where it is dug up from the surface. Also known as openpit mining or opencast mining, it is the most common form of extraction for minerals or coal in Australia.
Other huge excavators include the EX80006 and the PC80006. 2. Dump Trucks. Dump trucks, also known as haul or tipper trucks, are widely used across the mining industry for the handling of heavy materials. These trucks are used around mining sites to transport materials and mined minerals and are equipped with an openbox ...

Opencut coal mining projects can have a range of environmental, cultural and social impacts that, in New South Wales (NSW), Australia, are required to be addressed as part of the environmental assessment (EA) process. While these impacts are often addressed within separate impact assessment frameworks, it is
Most of the coal mined in Australia is produced by opencut methods. In, for example, the total Australian production of black coal was about 405 Mt with roughly threequarters coming from opencut mines (Australian Coal Association, 2013).Hence, there is considerable potential for spontaneous combustion to occur in spoil over large areas.
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.
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 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.
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

Openpit mining is the process of extracting rock or minerals from the earth through their removal from an open pit or borrow. Sign in to download fullsize image Figure Openpit mine [16]. Surface mining is usually used to develop coal seams and deposits of many other minerals, but their feasibilities vary with the nature of the body ore.
Opencut coal mining produces large quantities of waste material that must be disposed of around the mine site. Some of this material may be sufficiently reactive to begin to selfheat which can ultimately lead to spontaneous combustion in the spoil piles at some mines. ...

In the longwall mining method, mine development is carried out in such a manner that large blocks of coal, usually 100 to 300 metres wide and 1,000 to 3,000 metres long, are available for complete extraction (see photograph).A block of coal is extracted in slices, the dimensions of which are fixed by the height of coal extracted, the width of the longwall face, and the thickness of the slice ...
Methods of extraction Coal extraction methods vary depending on whether the mine is an underground mine or a surface (also called open cast) mine. Additionally, coal seam thickness and geology are factors in the selection of a mining method. The most economical method of coal extraction for surface mines is the electric shovel or drag line.
The integration of these operations enables all sites to use a single coal handling and preparation plant (CHPP) and infrastructure at Mt Owen Mine. Glendell Mine is seeking approval to continue current open cut mining to the north of its existing operations through the Glendell Continued Operations Project. Ownership
