A tripartite MoU on 'Delineation of Surface coal fire and associated land subsidence in Jharia coalfield (2025-27), Jharkhand, using satellite based Remote sensing techniques' is signed amongst NRSC/ ISRO, Bharat Coking Coal Limited (BCCL), Dhanbad, Jharkhand and Central Mine Planning & Design Institute Limited (CMPDI) Ranchi, Jharkhand, on October 15, 2025.
In this study, NRSC/ ISRO will use AI based techniques to map coal fires using Thermal Infrared (TIR) and Short Wave Infrared (SWIR) remote sensing data on quarterly basis in Jharia Coalfield. In addition, SAR interferometric technique will be used to identify land subsidence in Jharia coal field on annual basis, using data from NISAR and Sentinel-1 satellites.
The results of the satellite-based analysis will be jointly validated on the ground. These maps will help BCCL to implement and monitor the Jharia Master Plan of Ministry of Coal, for appropriate management interventions.
