    MONITORING OF SUBSIDENCE IN KARVINÁ MINING REGION USING INSAR METHODS

  • Original language description

    Whole Karviná region (CZ) is strongly affected by intensive mining of black coal. Subsidence caused by undermining has to be monitored by modern methods, such as satellite radar interferometry (InSAR). Character of the area, velocity and spatial scale ofsubsidence are challenging limits of InSAR. These limits were investigated, optimizing scenarios were found to increase the performance of InSAR techniques using C-band and L-band data to detect and estimate deformations due to subsidence in the region.While extents of subsidence troughs are often possible to delimitate, the deformation rates are usually underestimated. This was compared also to existing data from levelling. Thanks to InSAR ability to detect millimetre changes, a strong potential is seen in monitoring of slow deformations such as decay subsidence after closure of mines. InSAR techniques were evaluated as appropriate for a systematic monitoring of subsidence in the region, as complementary to levelling measurements.
