Coal mines emit more methane than oil-and-gas .

Methane emissions from coal mines could be more than double previous estimates, according to a new study. The fossil-fuel industry is understood to be one of the biggest sources of atmospheric methane, primarily due to leaks from the production of oil and gas.. However, a new paper published in the Journal of Cleaner Production suggests that coal mining may actually be a bigger contributor to ...

Bottom-Up Estimates of Coal Mine Methane .

China has large but uncertain coal mine methane (CMM) emissions. Inverse modeling (top-down) analyses of atmospheric methane observations can help improve the emission estimates but require reliable emission patterns as prior information. To serve this urgent need, we developed a high-resolution (0.25° × 0.25°) methane emission inventory for China's coal mining using a recent publicly ...
