How Does Mining Affect the Environment LoveToKnow

Mine Atmosphere (mine air), atmospheric air pumped or blown into underground mining excavations as it passes through the excavations, the air undergoes changes in composition, temperature, and humidity. In comparison with surface atmospheric air, mine air often contains less O2 and more N2 and CO2 because of oxidizing processes and the release of CO2

Air pollution from coal mines SourceWatch

Coal also contains methane (CH4), a potent greenhouse gas that contributes to global warming, which is released into the atmosphere during mining. On average, the deeper a mine, the more methane it generates, although methane emission depends on the mining methods, depth of coal mining, coal quality, and entrapped gas content in coal seams.
