  • Methane Emissions from Coal Mines Are Higher Than

    2021 2 1   Methane emissions are a constant concern at coal mines, which vent the gas as it's emitted when coal seams are disturbed. While methane produced in some industries is captured and used to create additional energy, it's more difficult to capture from coal mines, where the gas typically makes up a tiny fraction of the overall air stream.
