“…Fruitful results with regard to wide applications have been reported by InSAR researchers in the past 15 years [5][6][7]. However, in this study, both DInSAR and PSI/SBAS methods revealed their limitations when applied to a mountainous mining area with fast earth surface movements [6][7][8]. Based on the requirements from mining engineering and the different features of various InSAR techniques, a combined technique SBAS-DInSAR is applied to this mountainous area that is severely affected by mining activities.…”

Interferometric Synthetic Aperture Radar (InSAR) and Differential Interferometric Synthetic Aperture Radar (DInSAR) have shown numerous applications for subsidence monitoring. In the past 10 years, the Persistent Scatterer InSAR (PSI) and Small BAseline Subset (SBAS) approaches were developed to overcome the problem of decorrelation and atmospheric effects, which are common in interferograms. However, DInSAR or PSI applications in rural areas, especially in mountainous regions, can be extremely challenging. In this study we have employed a combined technique, i.e., SBAS-DInSAR, to a mountainous area that is severely affected by mining activities. In addition, L-band (ALOS) and C-band (ENVISAT) data sets, 21 TerraSAR-X images provided by German Aerospace Center (DLR) with a high resolution have been used. In order to evaluate the ability of TerraSAR-X for mining monitoring, we present a case study of TerraSAR-X SAR images for Subsidence Hazard Boundary (SHB) extraction. The resulting data analysis gives an initial evaluation of InSAR applications within a mountainous region where fast movements and big phase OPEN ACCESS Remote Sens. 2014, 6 1477 gradients are common. Moreover, the experiment of four-dimension (4-D) Tomography SAR (TomoSAR) for structure monitoring inside the mining area indicates a potential near all-wave monitoring, which is an extension of conventional InSAR.

“…Recently, Solari et al 57 and Crosetto et al 52 have described PSInSAR as a powerful remote sensing technique. Using 57 ERS 1/2 data and PSI technique Colesanti et al 38 identified precursor signs of collapse 10 months preceding the major collapse event affecting an area of ~300  300 m 2 , which occurred in February 1999 at the iron mining site of Roncourt, France. They established the relevance of the PSInSAR technique in studying the deformation before the major subsidence, when no levelling data were recorded.…”

“…Many PSI approaches have been developed over the years; their description is beyond the scope of this article. Examples of PSInSAR application in the field of mine surface 14,15,25,26,28,30,34,35,38 and urban [54][55][56][57][58][59][60][61][62][63][64] subsidence have shown the large spectrum of this technique on ground deformation assessment. About 21 TerraSAR X-band ( -3.1 cm) images have been used by Liu et al 28 to extract subsidence hazard map (SHM) around Xishan coal mine in China, that suffered from subsidence related to underground mining activities.…”

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.

“…For instance, successful land deformation estimates have demonstrated the potential of this technique for a wide range of applications related to landslides (Colesanti et al, 2003;Hilley et al, 2004;Bovenga et al, 2012), land subsidence caused by groundwater pumping (Tomás et al, 2005;Stramondo et al, 2007;Bell et al, 2008;Heleno et al, 2011) and mining (Colesanti et al, 2005;Jung et al, 2007), or urban monitoring Vallone et al, 2008;Cigna et al, 2012). This paper is focused on the application of Persistent Scatterer Interferometry (PSI; Ferretti et al, 2000Ferretti et al, , 2001 for land subsidence detection and measurement.…”

Abstract. Persistent Scatterer Interferometry (PSI) is a remote sensing technique used to measure and monitor land deformation from a stack of interferometric SAR images. The main products that can be derived using the PSI technique are the deformation maps and the time series of deformation. In this paper, an approach to apply the PSI technique to a stack of Sentinel-1 images is described. Moreover, the problems encountered during the processing are detailed and an explanation of how they were dealt with is provided. Finally, Sentinel-1 deformation maps and time series obtained over the metropolitan area of Mexico DF are shown.
