Deformation Monitoring Using D-InSAR Technique in Coalfield of Korba Chhattisgarh, India

Mining has become the major source for the development of any country by producing various economical minerals. Due to the extraction of assets, mine deformation is the collective phenomena in and around mines. It is a global problem, due to its adverse effect on land and its local ecosystem. Spaceborne Radar data and Interferometry Synthetic Aperture Radar (InSAR) techniques have been used for deformation monitoring. The Differential Interferometry Synthetic Aperture Radar (DInSAR) is an InSAR technique which is used for detecting deformation with millimetre accuracy. Three Sentinel-1 C band images from February 2015 to February 2019 have been used from 2015 to 2019 for deformation in and around coalfields of Korba, Chhattisgarh, India. Using sentinel-1 imaginary with high-resolution optical imaginary, the results show in 2016 has good coherence and in 2019 high deformation. The Interferometry technique is a competent tool for measuring the deformation in coal mines of Korba, Chhattisgarh, India.
