Monitoring subsidence in the surrounding area during mining projects is crucial for ensuring the safety and stability of both human-made structures and natural systems.

In this case, where the effects of longwall mining operations over a large area needed to be determined, InSAR proved a powerful tool for conducting this analysis. By utilising satellite-borne radar systems, InSAR enables continuous and precise monitoring of subsidence over large areas with remarkable accuracy.

Unlike conventional in-situ monitoring, which typically cover limited, discreet points and sections, InSAR provides a comprehensive view of deformation across an expansive region. This capability is particularly valuable in mining projects where subsidence can have far reaching consequences.

The extent and magnitude of mining-induced settlement that coincided with mining operations in different areas were determined by InSAR analysis of a time series of satellite images.
