What is coal seam gas (CSG)? Coal seam gas, or coal bed methane (CBM, is a form of natural gas, typically extracted from coal seams at depths of metres. It is a colourless, odourless, nontoxic mixture of a number of gases but mostly made up of methane (generally 9597 per cent pure methane). Coal seam gas has been part of Australia's ...

Mining coal. Coal miners use large machines to remove coal from the earth. Many coal deposits, called coal beds or seams, are near the earth's surface, but others are deep mining methods allow coal miners to easily reach most of the nation's coal reserves and to produce about three times more coal in one hour than in 1978.

Coal Seam Gas. Coal Seam Gas (CSG) is a naturally occurring methane gas found in most coal seams and is similar to conventional natural gas. In Australia the commercial production of CSG commenced in 1996 in the Bowen Basin, Queensland. Since then production has increased rapidly, particularly during the first decade of the 21st century.

Coal preparation plants that employ fine coal cleaning by froth flotation can produce an unacceptable amount of moisture in the product. Thermal drying, in which the wet coal is dried in the hot gas generated by a coalor gasfired burner, is used in some plants to reduce the moisture content. Refuse and tailings management.

Owing to the exhaustion of shallow coal resources, deep mining has been occupied in coal mines. Deep buried coal seams are featured by the great ground stress, high gas pressure, and low permeability, which boost the risk of gas disasters and thus dramatically threaten the security about coal mines. Coal seam gas pressure and gas content can be decreased by gas extraction, which is the primary ...
