Characteristics of coal mine ventilation air flows.

Coal mine methane (CMM) is not only a greenhouse gas but also a wasted energy resource if not utilised. Underground coal mining is by far the most important source of fugitive methane emissions, and approximately 70% of all coal mining related methane is emitted to the atmosphere through mine ventilation

U.S. Underground Coal Mine Ventilation Air Methane Exhaust

Gassy underground coal mines can emit methane into the atmosphere from a number of sources, including the ventilation system exhaust. In fact, mine ventilation systems typically are the largest source of methane emissions from underground coal mines. In 2008, U.S. coal mines released 101 billion cubic feet (Bcf) of ventilation air methane (VAM
