Abstract
Variations taking place in the chemical specifications (moisture, volatile matter, fixed carbon, calorificvalue etc.) of the coal samples with two different particle sizes (35 and 200 mesh) on the effect of the selfignition liability were examined. The coal samples in concern were preserved under different storingconditions for a period of 16 weeks. These samples of coal were upheld in different mediums such asnitrogen tank, deep freezer and oven under the pre-determined constant temperatures of -25, 18 and 30°Crespectively. In order to determine the tendency of spontaneous combustion for the coal samples, themethod of crossing point was used. As a concluding remark, it may be stated that there is an expressiverelation between the liability index (IFCC) and the chemical features of the coal samples.
