چکیده

Differential SAR Interferometry (D-InSAR) is an effective tool in monitoring land subsidence because of its greater coverage area and better resolution of height change. A series of Japanese Earth Resources Satallite-1 (JERS-1) images from 1992 to 1998 has been used in monitoring the mine subsidence in the test site of this study, one of the important coal mining areas in China. D-InSAR procedure is demonstrated in this paper by using repeat-pass satellite images. The results show that land subsidence was serious, and JERS-1 is capable of detecting the mine subsidence.

Application of Repeat-pass DInSAR and GIS for Underground Mine Subsidence Monitoring

This research used both ERS and JERS-1 images to investigate the feasibility of differential radar interferometry (DInSAR) for mine subsidence monitoring in the state of New South Wales, Australia. DInSAR results are analysed and validated with the aid of Geographic Information System (GIS) tools. The drawbacks of using interferometric measurements for mine subsidence monitoring are discussed. ...

Assessment of radar interferometry performance for ground subsidence monitoring due to underground mining

This paper describes the results from the recently launched SAR satellites for the purpose of subsidence monitoring over underground coal mine sites in the state of New South Wales, Australia, using differential interferometric synthetic aperture radar (DInSAR) technique. The quality of the mine subsidence monitoring results is mainly constrained by noise due to the spatial and temporal decorre...

Radar Interferometry for Mining Subsidence Monitoring

Coal mining activities all over the world often introduce serious environmental impact to the local regions, such as the occurrence of land subsidence. Conventional subsidence monitoring is done by precision leveling and GPS surveying. However, recent studies show that differential interferometric synthetic aperture radar (DInSAR) is capable of monitoring land subsidence at sub-cm accuracy. In ...

Mine Subsidence Monitoring: a Comparison among Envisat, Ers and Jers-1

This paper reports the progress of the Envisat CAL/VAL Project No 1078. Subsidence in an underground coal mining region southwest of Sydney, Australia, has been monitored using ERS and JERS-1. Seven Envisat images have been acquired in various imaging modes from both ascending and descending passes over the same mining region. More Envisat images have been scheduled and will be acquired in the ...
