摘要：Detection of the vertical ground displacements in mining areas using PSInSAR (Permanent Scatterer Synthetic Aperture Radar Interferometry) data in a northern-eastern part of Upper Silesia Coal Basin is presented in the paper. PSInSAR technique improves the ability to determine small-scale displacements of individual features (scatterers) on the surface. It uses radar images collected over the target area by a SAR satellite between 1992 and 2003. Using the PSInSAR method,we can resolve surface motions at a level of 0.5 mm/year,and resolve very small-scale features,including motions of individual targets such as roofs,pipelines,bridges. These small movements might result from regional isostatic movements of Upper Silesia region and/or the subsiding caused by mining activity. Analysis of subsiding values in Dabrowskie Coal Basin mining area has been performed using geostatistic methods. These methods use the semivariogram function, which describes dissimilarity between the parameter values,depending on the distance between places,where it was measured and the mutual orientation. Results obtained from geostatistical analysis of PSInSAR data do not indicate the dependency between values of ground motion and mining areas locations. In contrary,the subsiding revealed by PSInSAR technique distinctly indicates a correlation with faults system. It was shown that the greatest values of ground settlements occur in the downthrown blocks and near zones,at the crossing point of the faults lines.
