Coal Mining Process. In Queensland, coal mining is primarily carried out using two methods: opencut mining and underground mining. Opencut mining is the more common method and involves removing the surface layers of soil and rock to expose the coal seams. Once the coal is exposed, it is extracted using large equipment, such as draglines and ...

Coal is a combustible black or brownishblack sedimentary rock, formed as rock strata called coal is mostly carbon with variable amounts of other elements, chiefly hydrogen, sulfur, oxygen, and nitrogen. Coal is a type of fossil fuel, formed when dead plant matter decays into peat and is converted into coal by the heat and pressure of deep burial over millions of years.

Coal is generally produced in opencut mines in Australia because the coal seams are close to the surface. This makes it more economical to mine, and given the highquality of the resource, Australia's black and brown coal are strong commodities on the international market. How Is Coal Mined and Processed?

The process is repeated until the coal seam is mined. Another method, called longwall mining, accounts for about 20 percent of production. This method involves pulling a cutting machine across a 400 to 600 foot long face (longwall) of the coal seam. This machine has a revolving cylinder with tungsten bits that shear off the coal.

Bituminous: Even greater pressure results in the creation of bituminous, or "soft" coal. This is the type most commonly used for electric power generation in the It has a higher heating value than either lignite or subbituminous, but less than that of anthracite. Bituminous coal is mined chiefly in Appalachia and the Midwest.

Coal blending is the process of mixing coals after coal has been mined to achieve quality attributes that are desirable for the coal's intended application ( steam generation, coking). The quality attributes that are most important in blending will differ from one mine site to another and also depend on how the coal seams vary in quality and their final intended use.

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. The technique of opencut mining is used when the deposits are close enough to the surface to be readily extracted.
