“…The detection of precursors of mine-subsidence-induced micro seismicity are of great interest to the research community: Acoustic emission techniques [144][145][146], infrared thermography [151], laser scanning [152] and the SAR (synthetic aperture radar) techniques [153][154][155][156][157][158] have been utilized to study the precursors of rock failure. SAR techniques, in particular, may have the most potential to assess the performance of partial extraction mines, because they can provide accurate, cumulative regional displacements of ground surface.…”

Abstract:Partial extraction methods such as underground strip pillar mining or room-and-pillar mining are widely adopted techniques to control ground subsidence. However, pillar failure in partial extraction mines may introduce violent secondary ground collapses. The stability of partial extraction mines dictates the safety of ground surface structures and the environmental health state of the surrounding mining areas. To reuse mining subsidence lands, it is necessary to evaluate the stability of the land through mine subsidence assessments. This paper summarizes current pillar stability assessment methods and their limitations, and the rock mechanics associated with the stability of abandoned mines. The effects of multiple factors that affect mine stability are discussed in detail; special attention has been extended to discuss the weathering effects associated with infused water and spontaneous combustion, as these are some key reasons for pillar strength degradation in abandoned mines. The mechanism of mine collapse and the corresponding post-mining disasters are also summarized. Finally, suggestions and strategies to improve current mine stability assessment methods are proposed based on the perspective of subsidence control.

“…The Babadag landslide has been evaluated from Envisat in a previous work (Lazecký et al, 2015). Because of low number of images and high rate of decorrelation in the area (also due to fast movements), the result could be achieved only using an MT-InSAR methodology using only coherent spatially filtered interferograms rather than the whole time series in the PS algorithm.…”

ABSTRACT:Slope deformation is one of the typical geohazards that causes an extensive economic damage in mountainous regions. As such, they are usually intensively monitored by means of modern expertise commonly by national geological or emergency services. Resulting landslide susceptibility maps, or landslide inventories, offer an overview of areas affected by previously activated landslides as well as slopes known to be unstable currently. Current slope instabilities easily transform into a landslide after various triggering factors, such as an intensive rainfall or a melting snow cover. In these inventories, the majority of the existing landslide-affected slopes are marked as either stable or active, after a continuous investigative work of the experts in geology. In this paper we demonstrate the applicability of Sentinel-1A satellite SAR interferometry (InSAR) to assist by identifying slope movement activity and use the information to update national landslide inventories. This can be done reliably in cases of semi-arid regions or low vegetated slopes. We perform several analyses based on multitemporal InSAR techniques of Sentinel-1A data over selected areas prone to landslides.

“…Babadag is a small town of Turkey and 30 km away from the centre of the city Denizli in Aegean region (Lat: 37°48'38.37"N, Lon: 28°51'33.38"E) which has been seriously affected by a landslide phenomena since last 60 years. The Babadag landslide has been evaluated from Envisat in a previous work (Lazecký et al, 2015). Because of low number of images and high rate of decorrelation in the area (also due to fast movements), the result could be achieved only using an MT-InSAR methodology using only coherent spatially filtered interferograms rather than the whole time series in the PS algorithm.…”
