“…Many authors have reported that the DInSAR results have shown good agreement when compared with groundbased measurements 4,13,14,16,34,35,37,42,45,58,59,61,66,67 and provide reliable estimates of subsidence, particularly in an urban environment. A comparison of precise levelling and persistent scatterer SAR interferometry has been done 58,59 and PSI results show good agreement with the levelling data.…”

“…A slow and local phenomenon of subsidence due to underground coal mining was identified near Gardanne, France by Carnec and Delacourt 4 from images acquired by ERS-1/ERS-2 satellites between 1992 and 1995. Interferometric monitoring has shown that the impact of subsidence on the surface migrated all along the path of advancement of the underground operations establishing a direct relationship between them 4,26,35,37 . The application of SAR interferometry to identify surface displacements through DInSAR has shown its great potential and has developed manifold over the last decade.…”

“…Radar interferometric applications are well explained by Massonnet and Feigl 3 . SAR interferometry was successfully applied by Carnec and Delacourt 4 to study the subsidence caused by underground coal mining. In the last decade, the spaceborne interferometric synthetic aperture radar (InSAR) technique has established its utility for detecting ground deformation.…”

“…Coal mining subsidence has received worldwide attention, but less information is available on subsidence impacts due to hard-rock underground mining, particularly in India. Most studies of surface subsidence using SAR interferometry worldwide have been done on underground coal mines 4,5, . DInSAR techniques have been demonstrated as an effective tool to monitor the surface subsidence-prone area due to mining activities in Jharia coal field, Jharkhand, India …”

Most studies of surface subsidence and its impacts have been done on underground coal mines. There are few studies on the occurrences of surface subsidence in underground metal mines, particularly in India, even though the fundamental subsidence engineering principles are the same for both coal and metal mines. The current ground-based measurement techniques monitor ground subsidence on a particular point and are time-consuming as well as costly. To study hardrock mine surface deformation due to underground mining, new and effective technologies must be adopted. The spaceborne subsidence monitoring has emerged as a better technique after the development of satellite radar interferometry. The technology is fast improving with enhanced synthetic aperture radar (SAR) sensors on different spaceborne platforms. Differential interferometric SAR techniques are widely used to measure the topographic profile and surface deformations. This article reviews the applications of spaceborne SAR interferometric techniques in the prediction and monitoring of surface subsidence due to underground mining.

“…Consequently, groundwater may intrude the surface level, form new waterbodies and cause inundation. This, in turn, leads to several adverse environmental impacts, such as vegetation degradation, soil erosion, flooding, sinkhole formation, and soil and water contamination [5][6][7][8] as well as to damages of infrastructures [9]. The geological changes and associated environmental impacts may continue even after reclamations if mines are not properly backfilled [10][11][12].…”

Abstract:Mining for resources extraction may lead to several geological and associated environmental changes due to ground movements, collision with mining cavities and deformation of aquifers. Geological changes may continue in a reclaimed mine area, and the deformed aquifers may entail a breakdown of substrates and an increase in ground water tables, which may cause surface area inundation. Consequently, a reclaimed mine area may experience surface area collapse, i.e. subsidence, and degradation of vegetation health. Thus, monitoring short-term landscape dynamics in a reclaimed mine area may provide important information on the long-term geological and environmental impacts of mining activities. We studied landscape dynamics in Kirchheller Heide, Germany, which experienced extensive soil movement due to longwall mining without stowing, using Landsat imageries between 2013 and 2016. A Random Forest image classification technique was applied to analyse land-use and land-cover dynamics and the growth of wetland areas was assessed using a Spectral Mixture Analysis (SMA). We also analyzed the changes in vegetation health using a Normalized Difference Vegetation Index (NDVI). We observed a 19.9% growth of wetland area within the four years with 87.2% of growth in the coverage of two major waterbodies in the reclaimed mine area. NDVI values indicate that 66.5% of the vegetation of the study area was degraded due to changes in ground water tables and surface flooding. Our results inform environmental management and mining reclamation authorities about the subsidence spots and priority mitigation areas from land surface and vegetation degradation in Kirchheller Heide.

We used two “vintages” of ambient seismic noise recorded at the Valhall Life of the Field Seismic network in 2004 and 2005 to perform a passive time‐lapse imaging of the subsurface. First, the cross correlations between each pair of stations were computed for both vintages to extract Scholte waves. Second, the relative velocity variations between the 2004 and 2005 cross correlations were measured on the ballistic waves using the Moving‐Window Cross‐Spectral technique. Finally, the best quality relative velocity variation measurements were regionalized using a modified eikonal tomography technique. The results, albeit noisy because of the short duration of the available records, show a large patch of increased seismic velocity in the southern part of the network and a weaker anomaly in the northern part. The southern increase of velocity can be attributed to the exploitation of the southern flank of the Valhall reservoir with new wells and is in good agreement with a previous time‐lapse study using Scholte waves.
