coalbed methane mines

Assessing Emissions from Active and Abandoned Coal Mines

Abandoned mines that are sealed properly may become gas reservoirs from which methane can be extracted and utilized by available technologies. Capturing and utilizing coal mine and abandoned mine methane can alleviate the harmful effects of methane emissions to the atmosphere and can provide an energy resource through use of the recovered gas.
