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.
