Mine gas mining Britannica

Mine gas, any of various harmful vapours produced during mining operations. The gases are frequently called damps (German Dampf, “vapour”). Firedamp is a gas that occurs naturally in coal seams. The gas is nearly always methane (CH 4) and is highly inflammable and explosive when present in the air in a proportion of 5 to 14 percent.White damp, or carbon monoxide (CO), is a particularly ...

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

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 ...
