    Feb 01 2021 Methane emissions are a constant concern at coal mines which vent the gas as its emitted when coal seams are disturbed. While methane produced in some industries is captured and used to create additional energy its more difficult to capture from coal mines where the gas typically makes up a tiny fraction of the overall air stream.

  • Forecasting Methane Emissions from Hard Coal Mines

    Forecasting Methane Emissions from Hard Coal Mines

    With regard to underground mining methane is a gas that on the one hand poses a threat to the exploitation process and on the other hand creates an opportunity for economic development. As a result of coal exploitation large amounts of coal enter the natural environment mainly through ventilation systems. Since methane is a greenhouse gas its emission has a significant impact on global .

    Overviews of methane emissions from coal mining were compiled by Oberschelp et al.57 and specifically for Germany by the Federal German Environment Agency UBA58. Our collation of coal methane content data for coal and lignite used in Germany is mostly based on these studies with some updated and additional data i.e. for Colombia and South Africa Table S1.

  • Methane emission in coal mines effects of oil and gas wells

    Methane emission in coal mines effects of oil and gas wells

    The method of moving averages was found useful in assessing the nature of methane emission in coal mines. Emission rates were influenced markedly by the presence of abandoned oil and gas wells in the vicinity of the mine. Such wells appeared to increase the flow rate of methane into the mine by a factor of 2 to 30 in an active mine in the .
