With the intense focus on global GHG management and reduction, to slow the rate of climate change, significant community and political pressure to reduce gas emissionis mounting from coal mining . This paper discusses the various sources of gas emission from an operating underground coal mine, with.

Assessing Emissions From Active And Abandoned Coal Mines

Assessing Emissions from Active and Abandoned Coal Mines. The gas emission zone liberates and accumulates significant amounts of coal mine methane as a by-product of active mining. 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.
