Abstract
The Scanning Electron Micrography of bulk coal samples from Dishergarh, Sirpur and Kajora areas of Raniganj Coalfield has been attempted with a view to find out the role of microstructures in promoting the spontaneous combustion of these coals. Microanalysis of vitrain and c1arain has shown that these bands of R-VIII seam are highly porous as compared to the overlying and underlying seams. Further, finely dispersed pyrite has also been observed filling these micropores. It is concluded that the occurrence of ubiquitous micropores could be a prevalent factor responsible for the spontaneous combustion property of these coals in different ways.
