Moderate resolution thermal remote sensing data is suitable for mapping thermal anomaly caused by coal fires. Coal fires of two major coal fires are being are studied and dynamicity of these coal fires are also being observed. Geoenvironmental studies focus to map the coal fires; which are the important causes for environmental hazards ( causing subsidence by burning out coal faster, taking lives) in colliery areas. Coal fires are mapped for Jharia coal field to understand the dynamicity of thermal anomaly resulted due to coal fires for the period of 2003-2006. The study has also discussed the reason behind such propagation. Coal fire map is also derived for Raniganj coal field area. It has been observed that coal fires are associated with open cast mines and associated with regional structures. Image Shows Land Subsidence areas in Jharia Coalfield during 2003-07 delineated using SAR Data & Radar Interferometry Technique. This information can be used to prevent future mine roof collapse.
