Comparative analysis of coal and coal-shale intrinsic factors affecting spontaneous combustion
International Journal of Coal Science & Technology, 2018 Coal and coal-shales tend to undergo spontaneous combustion under favourable atmospheric conditions. Spontaneous combustion liability index and intrinsic properties of coals and coal-shales varies between (above and below) coal seams.
