The coal seams are generally filled with water and it is the pressure of the water that keeps the gas as a thin film on the surface of the coal. The technical term for this is ''adsorption''. Natural gas in coal seams in Australia is not a new discovery. It was first identified when coal mining began in the early 1900s.
Coal seam definition is a bed of coal usually thick enough to be profitably mined. a bed of coal usually thick enough to be profitably mined. See the full definition ... state officials approved new strip mining practices that allowed companies to blast away at the summits of West ia mountains to gain easier access to coal seams.
Jan 31, 2019· Mining Coal Seam Gas. EDO NSW has produced a number of resources on mining and coal seam gas. EDO NSW undertakes law reform work relevant to mining and coal seam gas. Read our submissions below. EDO NSW represents individuals and community groups in public interest litigation to protect the environment.
Coal seam gas (CSG) mining is a risky, invasive form of unconventional gas mining. Coal seam gas extraction usually involves tens of thousands of gas wells, with roads, pipelines, compressor stations, wastewater dams, and other infrastructure. A CSG project can spread across hundreds of thousands of hectares of land.
Growth in coal seam gas (CSG) in Queensland has been rapid over the past 15 years, peaking at 1,634 wells drilled in 201314. This growth will support the more than 70 billion worth of investment in 3 liquefied natural gas (LNG) projects that will produce approximately 26 million tonnes per year of LNG from 2015 onwards.
Coal seam methane. Methane (CH4) is a gas formed as part of the process of coal formation. When coal is mined, methane is released from the coal seam and the surrounding disturbed rock strata. Methane can also be released as a result of natural erosion or faulting.
May 22, 2017· Anti coal seam gas mining rally outside parliament house in Sydney: CSG caused such a political headache on the state''s north coast that the .
Coal Seam Gas / Coal Bed Methane. Coal Seam Gas (CSG) or Coal Bed Methane (CBM) is primary coal seam gas collected from unmined coal coal seams are drilled down into, releasing the associated gas which is extracted and can be used to generate electricity.

Sep 27, 2016· Introduction. In March 2012, South Australia signed the National Partnership Agreement on Coal Seam Gas and Large Coal Mining Development (NPA). Queensland, New South Wales and Victoria are also signed parties to the NPA. The Agreement strengthens the regulation of coal seam gas (CSG) and large coal mining by informing decisions with bestavailable science and advice from the .
In conventional gas fields, the gas exists in permeable sandstone reservoirs. CSG, however, is found in coal seams, where underground water pressure keeps it contained. Pumping water out of the coal seam releases this pressure and allows gas to escape from the coal into a well.
Coalseam fires can be ignited by selfheating of lowtemperature oxidation, lightning, wildfires and even arson. Coalseam fires have been slowly shaping the lithosphere and changing atmosphere, but this pace has become fast and extensive at modern times, triggered by enormous mining activities.
NSW Gas Plan. The NSW Gas Plan sets out the regulations for all Coal Seam Gas (CSG) activities in the State. Importantly, the NSW Gas Plan is based on the findings of the Chief Scientist and Engineer''s Independent Review of CSG Activities in New South Wales.. The State Environmental Planning Policy (Mining, Petroleum Production and Extractive Industries) 2007 (Mining SEPP) establishes a ...
A coal seam is a dark brown or black banded deposit of coal that is visible within layers of rock. These seams are located underground and can be mined using either deep mining or strip mining techniques depending on their proximity to the surface. These seams undergo normal coal formation and serve as a conventional coal reserves of coal are immense, and are the largest of all of ...
The gas is channeled to processing facilities for distribution while water is piped to water treatment facilities. CSG producers aim to satisfy and expand demand and equally important, to replace the diminishing supply of conventional gas. Coal seam gas production involves drilling wells into the underground coal seams.

Coal Seam Gas in Australia. Historically, coal seam gas was the cause of most mining explosions and was therefore ventilated out of a coal mine. However, there is now a growing global awareness that coal seam gas is a viable energy resource, enabled by emerging extraction and utilisation technologies.
