SAR interferometry, as a method of area-based geodynamic control on mineral deposits and adjacent urbanized areas

Abstract

As a rule, geodynamic monitoring uses complex approach and monitoring commences from the start of field exploration throughout the whole period of field exploitation. For this purpose specialised geodynamic polygons used for periodic or permanent monitoring and further study of tectonic, technogenic, physical and chemical and other processes that lead to hazardous deformations in earth core. Mineral fields are referred to a number of priority facilities. In connection with the aforementioned, there was carried out radar survey data processing by differential interferometry in the territory of the Karaganda coal basin. The maps of vertical displacements based on SAR data of interferometry were constructed and analyzed, as well as a comprehensive interpretation and comparison of displacement results with underworked territories and adjacent infrastructure aimed at increasing the detection efficiency of catastrophic subsidence of the earth's surface under the influence of technogenic factors and seismogenerating zones.
