Subsurface coal fire mapping using magnetic survey at East Basuria Colliery, Jharkhand

The present study deals with the mapping and understanding of sub-surface coal fire on the basis of magnetic susceptibility of materials that changes with the temperatures rise above or below the Curie temperature. The magnetic data acquisition has been carried out using high resolution GSM-19T proton precession magnetometer. The acquired magnetic data have been processed and analyzed to study magnetic field anomaly of East Basuria Colliery in Jharia coalfield, Jharkhand, India for mapping and understanding of sub-surface coal fire. Residual component of the total magnetic field anomaly map of the area has been calculated to enhance and delineate the coal fire region.
