Integration of the Leveling Observations and Psinsar Results for Monitoring Deformations Caused by Underground Mining

Deformations in mining areas are of key importance for human safety and the use of infrastructure. The surface observation of the scale of movements allows for the assessment of the correctness of mining subsidence modeling and forecasting. The study area is located above the underground mining. Levelling measurements were made to observe subsidence. The obtained results indicated anomalies in the terrain deformation. This hypothesis was verified using the PSInSAR technique. At the same time, the analysis carried out allowed for the detection of 3 regions forming subsidence troughs. Additionally, the observations made it possible to verify the stability of the levelling points. These results will allow for better management in planning subsequent measurement campaigns.
