Underground coal mining is by far the most important source of fugitive methane emissions, and approximately 70 of all coal mining related methane is emitted to the atmosphere through mine ventilation.Jan 01, 2019 In underground coal mines, ventilation air quality must be monitored primarily for methane, oxygen deficiency, diesel exhaust, dust, and any signs of combustion, indicated by the presence of carbon monoxide. In metal and nonmetal mines, ventilation quantities are typically lower compared to coal mines, as explosive methane is generally not present.
