Detecting Methane from Coal Mining Ventilation Systems

Explosion of methane gas is the most common source of mining accidents, mainly in coals mines. Methane, an odorless, colorless gas, is trapped in mines as part of the coal formation process. When coal is formed from compressed plant matter, methane is produced as a by product.

How Coal Works Union of Concerned Scientists

Coal is formed when dead plant matter submerged in swamp environments is subjected to the geological forces of heat and pressure over hundreds of millions of years. Over time, the plant matter transforms from moist, low carbon peat, to coal, an energy and carbon dense black or brownish black sedimentary rock.

Coal mine methane Climate Technology Centre Network

Methane is the primary constituent of natural gas and is stored within coal as a result of the coalification process whereby plant material is converted to coal. Due to coal mining activities (and subsequent pressure decrease in coal seams), methane is released from the coal and surrounding strata. This leads to the build up of methane in mines, which potentially creates an explosive hazard.
