Surface Coal Mining Methods in Australia 5 2. Open cut mining methods strip mining Largescale open cut coal mining operations commenced in Australia in mid 1960s and since then there has been significan t developments in this method of mining. The mines are now operating at significantly higher annual tonnages, growing deeper, more complex and
The underground mining methods we use include room and pillar, narrow vein stoping and largescale mechanised mining. Room and pillar mining is a style of mining where tunnels are driven in a chess board pattern with massive square pillars between them which are gradually cut away as the work proceeds. We use this for mining coal.

Several benches may be in operation simultaneously in different parts of, and at different elevations in the open pit mine. Open pit mines can be used in coal mining, and they are used extensively in "hard rock" mining for ores such as metal ores, copper, gold, iron, aluminum, and many minerals.
Openpit mining or opencast mining refers to a method of extracting rock or minerals from the earth by their removal from an open pit or borrow. It is a form of surface mining. The term is used to differentiate this form of mining from extractive methods that require tunneling into the earth, like longwall mining.
however, for largescale open pit mining in particular, the truck and loader" material movement practice is the preferred method of materials handling (Czaplicki, 1992; Ta et al., 2005). Throughout this paper, we consider a loader" to be any type of high productivity excavating equipment, which may include a mining loader, shovel or excavator.
Open Cut and Underground Mining. Learn more about the Bowen Basin mining location. The Bowen Basin contains the largest coal reserves in Australia. This major coal producing region contains one of the world''s largest deposits of bituminous coal.
Open cast mining is a type of surface mining in which mineral resources are removed from the earth through large holes or pits dug into the surface. The term "open cast mining" is used most commonly in Great Britain. In the United States, open cast mining is usually called openpit or opencut mining.
outside. Augering can be regarded as a supplementary method for open cast mining in cases when coal seams in the highwall would otherwise remain unmined (unless recoverable by underground methods) or when rugged terrain would preclude economic stripping by conventional surface methods. Quarrying of dimension stone and highwall
Coal mining Coal mining Choosing a mining method: The various methods of mining a coal seam can be classified under two headings, surface mining and underground mining.
