  • Assessing Emissions from Active and Abandoned Coal Mines

    Assessing Emissions From Active And Abandoned Coal Mines

    In most active mines, coal mine methane is controlled by wellbores, called gob gas ventholes. Despite the presence of these wellbores, it is not possible to capture all of the methane generated within the gas emission zone. As a consequence, a large amount of gas migrates into the mine and is exhausted to the atmosphere with ventilation air. Eventually, part of the gas generated during mining stays in the emission zone, and with additional emissions,
