2012-08-30· underground coal mines, the CO and CO. 2. concentrations and their related ﬁre ratios may be affected by mine ventilation. In this study, CO and CO. 2. emissions from spontaneous heating of a U.S. coal sample were evaluated in an isothermal oven under different airﬂow ventilation rates ranging from 100 to 500 cm. 3 /min.
However, the rate of emission of CO 2 by this process is low. • Uncontrolled combustion: These emissions are from mine fires because of coal exploitation activities. • Abandoned coal mines: After closing and sealing of coal mines, CH 4 may still be emitted as a result of gas migrating through natural or man-made conduits.
