Özet:

 Accidents and loss of life can occur in surface mines due to large mass displacements landslides. In order to prevent these irreversible situations, it is very important to identify displacements in advance or to take necessary measures by obtaining early warning signs. Within the scope of this study, satellite radar images SAR, Synthetic Aperture Radar obtained from the European Space Agency ESA Sentinel-1A satellite were used to reveal the traceability and monitoring sensitivity of deformations and possible mass displacements in the dump area of a mining operation. The results obtained from 2 Global Positioning Systems GPS installed in the field were compared with the results obtained from satellite radar data and their compatibility with each other was evaluated. When the horizontalvertical velocity values obtained by decomposing the Sentinel-1A ascending and descending satellite line of sight LOS, Line Of Sight velocities were compared with the horizontalvertical velocity values of GPS, the results were statistically equal. GPS-based vertical velocities were -131.5 mmyear at GPS1 and -20.7 mmyear at GPS2, while Sentinel-1A-based velocities were -94.5 mmyear at GPS1 and -7.8 mmyear at GPS2. While both GPS and satellite-based vertical deformations show the same direction in the form of subsidence, the deformation velocity values obtained from satellite radar data are lower than GPS results. Horizontal deformations obtained with satellite radar data could not be determined in the northsouth direction due to satellite orbital motions, while they could be partially determined in the eastwest direction. GPS-based eastwest horizontal velocities were 2.8 mmyear in GPS1 and unsignificant velocity was found in GPS2. Satellite-based eastwest horizontal velocity values were 6.8 mmyear at GPS1 and 8.4 mmyear at GPS2.
