Coal Seam Gas – Coal Gas

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.

coal seam - an overview | ScienceDirect Topics

Coal seam gas, also known as coal bed methane, is a natural, colorless, odorless mixture of various gases (primarily methane) that is extracted from coal at a depth of ∼200–1000 m. The chemical composition of CSG and conventional gas is the same. Conventional natural gas reservoirs largely consist of porous sandstone formations capped by impermeable rock.

Coal Seam Gas | CSG | Coal Bed Methane | CBM

The gas composition is normally stable, meaning that the gas can be fed directly into the natural gas network or a gas engine. Methane is a gas formed as part of coalification (coal formation). When coal is mined, methane is inevitably released from the coal seam and the surrounding rock.
