Coal seam gas. Coal seam gas (CSG) is a type of unconventional gas. It is a natural gas, consisting primarily of methane, which is found in coal deposits. Coal seam gas collects in the coal seams by bonding to the surface of coal particles. The coal seams are generally filled with water, and it is the pressure of the water that keeps the gas as ...

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 ...

When rockbursts and coal and gas outbursts simultaneously occur in a coal mine, changes in gas adsorption (concentration of ambient methane) and displacement of coal and rock must occur. The coassociated minerals in coal reservoirs can affect the mechanical properties and methane adsorption capacity, which are commonly disregarded. It is important to construct compound molecular structure ...

Coal seam gas, also called coal bed methane, refers to naturally occurring methane in coal seams. The gas is held on coal surfaces and trapped by water pressure in the gaps and cracks in the coal seams. In order to allow the gas to flow, water is drawn away from the seams to release the gas into a gas well. The Victorian Government banned the ...

The coal seam lies at 12,316 working face, the mining gas content is about 4~6 m 3 /t, and absolute gas gush from the mine is 12~15 m 3 /min, which is a typical highstrength mining coal seam with low gas emission. As the depth and intensity of mining increases, conventional gas extraction can no longer meet requirements of safe operation.
