DInSAR for the Detection of Land Subsidence in Mining

DInSAR for the Detection of Land Subsidence in Mining

A brief summary of Thesis components

The scope of the project was achieved through learning to use and understand the Atlantis Earth-View InSAR software, which was utilised to enable the creation of a deformation map. A case study using satellite images of Appin took place through the Earth-View InSAR software. Based on this case study, a tutorial for using Earth-View InSAR was developed.

In addition a glossary of the software process was created, as was a ‘Defaults’ page. A brief discussion of near-future SAR satellite launches and their resulting impacts on SAR applications also transpired.

 

Overview

Underground mining results in alterations of ground surface elevations within mining regions. These alterations can be responsible for damage to the environment and infrastructure within the area. This can cause mining companies legal concerns over breach of contracts and damages owed to affected bodies. Tunnel collapses are also a major concern in mining. Deformation monitoring methods can assist in identifying unstable mines. It is for this reason that near real-time monitoring is required around a mining region.

A recent method of monitoring mining sites that is still being researched by academic “circles” is Differential Interferometric Synthetic Aperture Radar (DInSAR). This method uses satellites to detect ground displacements over large areas, with up to sub-centimetre accuracies.
