Our goal is to investigate in detail and to bring new comprehension of the mine life cycle. The dynamics of mining, especially in the case of horizontally evolving longwall technology, exhibit rapid surface changes. We use the classical approach of differential radar interferometry (DInSAR) with short temporal baselines (six days), which results in deformation maps with a low decorrelation between the satellite images. For the same time intervals, we compare the radar results with prediction models based on the Knothe–Budryk theory for mining subsidence. The validation of the results with ground levelling measurements reveals a high level of resemblance of the DInSAR subsidence maps (−0.04 m bias with respect to the levelling). On the other hand, aside from the explicable exaggeration, the location of the subsidence trough needs improvement in the forecasted deformations (0.2 km shift in location, a deformation velocity four times higher than in DInSAR). In addition, a time lag between DInSAR (compatible with extraction) and prediction is revealed. The model improvement can be achieved by including the DInSAR results in the elaboration of the model parameters. date: 2019 date_type: published publication: Remote Sensing volume: 11 number: 7 publisher: MDPI pagerange: 745 id_number: doi:10.3390/rs11070745 issn: 2072-4292 official_url: https://doi.org/10.3390/rs11070745 access_IS-EPOS: limited owner: Publisher acknowledgments2: EPOS-PL_project citation: Ilieva, Maya and Polanin, Piotr and Borkowski, Andrzej and Gruchlik, Piotr and Smolak, Kamil and Kowalski, Andrzej and Rohm, Witold (2019) Mining Deformation Life Cycle in the Light of InSAR and Deformation Models.
