Methane emissions from coal mines are higher than ...

Most coal has some methane (the main component of natural gas) trapped inside it. This methane is produced during the coal formation process and gets trapped on the surface of the coal in tiny pores and fractures. 1 Many coalbeds also contain large amounts of water; the pressure from this water keeps the methane in place. Coalbed methane is extracted by …

About Coal Mine Methane | UNECE

Natural gas systems and coal mines are the major sources of methane emissions in the energy sector (Figure 18 and Table 18). U.S. methane emissions from natural gas systems grew from 1990 to 2009 by 27 percent (39 MMTCO 2 e), largely because of increases in natural gas consumption. Emissions from coal mines declined from 1990 to 2002 and ...

Technology; Capturing Methane From the Coal Mines

Coal-mine gas is generated during coal mining, with the methane content of most coal mines being around 30 - 60 percent of the gas, which also consists partly of air. Two things justify the recovery of coal-mine gas: coal-mine safety and cutting methane emissions into the atmosphere. Recovered coal-mine gas can be used as energy or raw material for chemicals.

About Coal Mine Methane | UNECE

However, the methane/air proportion can change suddenly, thus complicating its use in gas engines. The methane recovered from working mines is done so thanks to two main concerns, these are mine safety and energy production benefits. Methane is released as a direct result of the physical process of coal extraction.
