What is Coal Bed Methane Gas?
Coal bed methane gas (CBM or coal seam methane), as the name suggests, is a by-product of the geological processes that created our waste deposits of coal. It’s original name was firedamp because it is the most dangerous of the explosive mine gases. Some coal measures contain more gas other contain less. Wikipedia, the free encyclopedia, defines CBM as: “Also called coal bed gas, the term refers to methane adsorbed into the solid matrix of the coal. It is called ‘sweet gas’ because of its lack of hydrogen sulfide. The presence of this gas is well known from its occurrence in underground coal mining, where it presents a serious safety risk. Coalbed methane, often referred to as CBM, is distinct from a typical sandstone or other conventional gas reservoir, as the methane is stored within the coal by a process called adsorption. The methane is in a near-liquid state, lining the inside of pores within the coal (called the matrix). The open fractures in the coal (called the cleats) can also
