摘要：Underground mining activities lead to ground movements at the earth surface. An area-wide monitoring and the documentation of mining induced influences are required by the mining authorities. Work done in the past confirmed a significant potential of SAR interferometric methods to contribute information to such monitoring. Nevertheless, in spite of advanced SAR interferometric processing techniques and numerous convincing results, there are general limitations to the utility of the application. For the monitoring of mining induced deformation information gaps may occur, especially in the case of high deformation rates. Another common problem of SAR interferometry is the loss of coherence in rural areas. The new generation of SAR sensors shows a significant improvement of the applicability of interferometric techniques for mining related surface deformation. The higher spatial resolution of the TerraSAR-X sensor and its shorter repeat intervals lead to easier phase unwrapping with the possibility to measure high deformation rates. Alternatively, the use of the longer L-band wavelength of ALOS PALSAR offers good possibilities in rural areas and in the case of fast surface movements. The German hard coal mining company RAG Aktiengesellschaft (RAG), in cooperation with the Clausthal University of Technology and GAMMA Remote Sensing set up the R&D project "GeoMon" to investigate the potential of the available new SAR sensors for monitoring surface deformations above an active and an abandoned mine. The results of the interferometric analysis using TerraSAR-X and ALOS PALSAR data will be presented combined with the validation of the results with comprehensive terrestrial measurements
