Abstract
Abstract. Natural Resources extraction for production of goods increases the stress on land and on the environment. Coal Mines are the primary source for energy production. This process increases the continuous deformation on land by disturbing equilibrium beneath the surface. Interferometry techniques have a capability to detect the minute deformation with millimetre precision on the ground using microwave SAR data. The study area covers the largest open cast coal mines of Asia. In this study for minute deformation identification, Persistent Scatterer Interferometry Synthetic Aperture Radar (PSInSAR) technique has been used. Research focuses on the application of PSInSAR technique for terrain deformation detection using 17 SAR scene of Korba, Chhattisgarh, India acquired by the Sentinel-1 satellite of European Space Agency. This technique is capable to monitor the minute deformation in the coal mines of Korba, Chhattisgarh, India. The results predicted that the area is deformed with the velocity up to 30 mm/year in the coal mines and surroundings areas. The PSInSAR technique with the Sentinel-1 data provides the proficient tool for deformation monitoring in coal mines of Korba.
Highlights
Mining deformation in the form of subsidence is the biggest problem in open cast and underground mines and their surrounding areas due to mining activities
In the Microwave technology, the Persistent Scatterer interferometry (PSInSAR) technology gives a new turn to monitor the subsidence/deformation. * The research focused on spaceborne synthetic aperture radar (SAR) imagery for monitoring mine subsidence which provided an alternative to prediction displacement (Engineering, Informatics, and Systems 2007)
The PSI products derived with the help of the 17 scenes of Interferometric Wide Swath (IW) Single Look Complex (SLC) Sentinel-1 images, spanning the period from February 2015 to February 2017 are accumulated displacement map and the time series of the deformation derived
Summary
Mining deformation in the form of subsidence is the biggest problem in open cast and underground mines and their surrounding areas due to mining activities. Interferometry SAR (InSAR)(Aydoner, Maktav, and Alparslan 2004) techniques are widely used, to measure the topographic profile and surface deformations(Ishwar and Kumar 2017)(Fulton 2000) and for subsidence monitoring(Strozzi et al 2001). SAR-Interferometry (InSAR) is one of the competent techniques used to understand the land surface motion and land subsidence (land surface sinking) (Ishwar and Kumar 2017) (Strozzi et al 2001) (Sahu, Pradhan, and Jade 2016) over a large area (Bonì et al 2017) at a cost lower than the traditional techniques(Ng et al 2011) (Ferretti, Prati, and Rocca 2001a).
