Satellite Differential Radar Interferometry (DInSAR) has demonstrated its ability for monitoring mine-induced ground subsidence. However, it is still a challenging task to routinely identify all mining activities from the large-scale coverage interferogram, especially the illegal mines. In response to this challenge an underground mining detection system based on DInSAR is described. The system is...
In the undermined Northern Moravia region, the land is subsiding even more than a metre per year causing damages to many human-made objects. Such a fast subsidence is almost not possible to estimate using multitemporal radar interferometry techniques that were applied to ERS-2 data of 1996-2001. Classic differential radar interferometry approaches were successfully applied allowing to visually interprete...
In view of the character of mining disaster and the limitation of traditional methods of earth surface deformation monitoring in western mining area, an attempt at adopting InSAR techniques in dynamic deformation monitoring in west mining area has been developed. This paper takes Shaanxi Province Binchang mining area as study area, processes the SAR image by differential interference, obtains the...
A novel Ground Based Synthetic Aperture Interferometric radar was set up for slope stability monitoring in open pit quarries. It is a wide view angle system which is easily adapted to the typical geometry of a quarry, and it automatically generates interferometric DEMs of the area under investigation. The system was tested during a 40 days field survey in a stone quarry in Tuscany, Italy.
In the past, the application of Persistent Scatterer Interferometry (PSI) was primarily possible in the case of slow (less than a few centimeters per year) uniform movements. In this paper, we show how PSI permits the monitoring of relatively fast (including rates up to > 50 cm/year) and nonuniform movements using TerraSAR-X repeat observations over deep-level mining. To enable this, parts of the...
In this work, DInSAR technique has been applied to the monitoring of mining induced land subsidence in many areas. In this paper, the DInSAR technique is used to process the space borne SAR data including C band ENVISAT ASAR and L band JERS, PALSAR SAR data to derive the temporal land subsidence information in Fengfeng coal mine area, Hebei province in China. Since JERS do not have precise orbit,...
A case study of INSAR application to monitor the ground subsidence of colliery area in Fengfeng coal mining area, Hebei Province, China is investigated in this paper. Using the data of ENVISAT ASAR and JERS SAR, the interferometric results of this area are derived. At the same time as acquisition of ENVISAT ASAR data, field leveling measurement in this area was carried out, and the historical excavation...
Since June 2006 the Remote Sensing Laboratory (RSLab) of the Technical University of Catalonia is carrying on a subsidence monitoring activity in Salient, a village in the central Catalonia. The project, in collaboration with the Cartographic Institute of Catalonia (ICC), aims at studying the deformation phenomenon induced by salt mining extraction of the past years using a ground-based SAR sensor...
