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.
Coal seam gas (CSG) is natural gas mainly composed of methane, the odourless and colourless gas used in homes and businesses. Natural gas from coal seams is used in exactly the same way as other natural gas, for cooking, heating, electricity production and to make products such as fertilisers.
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.
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.
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.
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 ...
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.

The Minister for Resources is usually responsible for
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.
Coalbed methane (CBM or coalbed methane), coalbed gas, coal seam gas (CSG), or coalmine methane (CMM) is a form of natural gas extracted from coal beds. In recent decades it has become an important source of energy in United States, Canada, Australia, and other countries. The term refers to methane adsorbed into the solid matrix of the coal.
Mar 08, 2016· Methane emissions are one of the major concerns surrounding coal seam gas. But we should also be paying attention to other sources of methane, in particular those from coal mining.
Mar 20, 2019· The coal seam gas industry and its regulators still have work to do in persuading local communities that old wells can be decommissioned without .
The process depressurises the coal seam, allowing the gas in the pores of the coal to be released and flow to the surface. The gas and liquid are brought to the surface via a pipe which is encased in layers of concrete and metal to prevent any leakage into permeable layers, including aquifers. On the surface, the gas is separated from the water.
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.
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 .
The Independent Expert Scientific Committee on Coal Seam Gas and Large Coal Mining Development is a statutory committee of leading scientists that independently advises government regulators on the impacts that coal seam gas and large coal mining development may have on .
The Australian Government plays an important role in protecting our environment from potential impacts of development activity, with a focus on matters of national environmental significance. In the case of development activity related to large coal mines and the extraction of coal seam gas, this includes potential impacts on water resources.
Thick coal seam is the main coal seam to achieve high efficiency coal mining. In this chapter, the common mining methods for thick coal seams are introduced. There is a largecuttingheight mining method and a topcoal caving mining method. Also, the ground control for the thick coal seam mining is described in this chapter.
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 .
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 ...
