An assessment of mine methane mitigation and utilisation ...

2005-1-1  Gas drained from coal mines typically contains 30–90% methane. Although coal mine methane is a potentially valuable fuel source, many mines vent it to the atmosphere, particularly post-drainage gas. Also some mines flare coal mine methane both from pre- and post-drainage gas, resulting in a significant waste of energy.
