In best practice, studies of the immediate environment are carried out several years before a coal mine opens in order to define the existing conditions and to identify potential problems. The studies look at the impact of mining on surface and ground water, soils, local land use

Surface mining and underground mining are the two major schools of coal mining. To qualify for surface mining, the coal deposits must be within 5080 meters of the surface. The job of a miner primarily involves removing overburden rock, soil, trees etc. that mix with the coal deposits and cover them near the earths surface.
When it comes to mining coal, there are two processes by which coal can be removed from the ground: surface mining, or underground mining. In Australia, the majority of coal mining is done via the opencast method, although often the method of choice is dependent on certain characteristics of the coal deposit 1.. The opencast, also referred to as the openpit method, is the ideal technique when
Shortwall mining, a method currently accounting for less than 1 percent of deep coal production, involves the use of a continuous mining machine with movable roof supports, similar to longwall. The continuous miner shears coal panels 150 to 200 feet (45 to 60 metres) wide and more than a halfmile (1 km) long, having regard to factors such as geological strata.
Surface mining can be used when the coal is buried less than 200 feet underground. In surface mining, giant machines remove the topsoil and layers of rock to expose large beds of coal. Once the mining is finished, the dirt and rock are returned to the pit, the topsoil is replaced, and the area is replanted. The land can then be used for

COAL INDUSTRY (ELECTRIC MACHINEMINING). (Hansard, 18 May 1938) The use of electricity is something new in coal mining. It is new in the sense that it is how being used at the coal face where there is always so much report adds: The use of electricallydriven coalface machinery is practically unknown, though some gate conveyors are electrically driven.

#0183;#32;Coalminers use electricpowered shuttle cars to transport coal from the coal bed to safer points in the mine. From there, miners can use standard scoops, or haulage vehicles, to drive their loads completely out of the mine. Miners of all types use haulage vehicles for various tasks.
Coal mining has been performed since the arrival of the Industrial Revolution in the mid18th century. Coal is used as a fuel primarily for steamgenerated electrical power plants, as well as being a component of certain industrial applications, such as steel manufacturing.
Coal mining is only a temporary use of land, so it is vital that rehabilitation of land takes place once mining operations have stopped. In best practice a detailed rehabilitation or reclamation plan is designed and approved for each coal mine, covering the period from the start of operations until well after mining
pit machinery can also be used for other purposes such as civil construction, whereas underground mining equipment is specialized and expensive. A number of surface mines operate 24 hours/da y and almost 365 days/year in order to use open pit machinery for as many hours as possible, thereby reducing the number of machines required.
