Open Cut Coal Mining Process
Coal Mining in Australia
· Coal Mining Trends. 80% of Australian coal produced is mined from opencut mines, whereas globally, opencut mining accounts for only 40% of coal produced. Queensland produces the most coal Australia wide. Opencut mining Is more affordable than underground mining and allows for 90% recovery of the raw resource in situ.
Open Cut Mining Process Coal
· 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.

outside the mining area for placement and storage. In the Midwest, where the surface topography and coal seams are generally flat, it is common to employ area strip mining in which the fragmented overburden is placed directly by large draglines in the space created where coal has been mined ().In some situations in the eastern United States, a coal seam occurring near the top of mountains is ...

Apr 04, 2019· Opencut coal mining can be more costeffective and safer than underground coal mining methods. Typical recoveries of 90% of the coal seam are achieved through open cut coal mining methods. However the environmental rehabilitation of sites is costly and must be achieved effectively according to regulatory requirements.

· Credit: BHP. BHP has started the process to seek approval for extending the operational life of the Mount Arthur Coal (Mt Arthur) mine in New South Wales, Australia, beyond the opencut approval's expiry on 30 June 2026. A major element of the planning approval is clearance to continuing operations through to 30 June 2045.

· The site is owned and operated by BHP Billiton, with the mining operations consisting of two opencut areas — the Northern Open Cut and the Southern Open Cut. More than 20 coal seams are mined at Mt Arthur, where thermal coal is produced for energyrelated customers in the area and internationally. Its annual coal production is more than 18Mt and has an estimated reserve life of 35 .

· Techniques of surface mining include: openpit mining, which is the recovery of materials from an open pit in the ground, quarrying, identical to openpit mining except that it refers to sand, stone and clay; Strip mining consisting of stripping off surface layers to reveal ore / seams below ; and mountaintop removal, commonly associated with coal mining, involving removing the top of a ...
The Four Main Methods of Mining
· Strip mining – Strip mining is the most common surface mining method used to mine coal and lignite. The process is done by removing a strip of overburden before mining a seam of mineral. Strip mining is done only when the ore body is in close proximity to the surface. Openpit mining – Openpit mining is the method in which minerals or ...

The Mining IOF program funded some work that was relevant to minerals separation (as part of a much broader program and not exclusively coal related), but new funding for this program (never more than 5 million per year) has been terminated and the program is being closed out. DOEFE had a solid fuels program, although it tended to fund more advanced work—such as chemical coal cleaning ...
