shown, the amount of mine emissions exceeded gas content of coal by a factor of 4. Kissell et al. (1973) observed similar trends for the U.S. coal mines and suggested that the mine emissions greatly exceeded (approximately 7 times) the amount expected from an analysis of coal gas content alone. The difference may be related to the differences in
mining. Emissions, during subsequent handling, processing and transportation of coal are termed post-mining emissions. Therefore coal normally continues to emit gas even after it has been mined, although more slowly than during the coal breakage stage. • Low temperature oxidation - These emissions arise because once coal is exposed to oxygen ...
