Comparative analysis of coal and coal-shale intrinsic factors affecting spontaneous combustion

open access: yesInternational 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.

Spontaneous Combustion of Coal (I)

open access: yesFire Science and Technology, 1985
Thermogravimetry of coal has been carried out by changing the oxygen concentration of the heating atmosphere, and the effect of oxygen in the concentration of 1-60% flow gas has been discussed based on the thermogravimetric curves. The kinetic parameters of exothermic oxidizing reaction of coal in the thermogravimetric, which has one of the critical ...
