SummaryTechnogenic causes of induced seismicity in the development of mineral deposits are mainly associatedwith the change in the strained state of rocks of the massif during mining operations. The geodynamic system imbalance triggers the mechanisms of its relaxation into a new geomechanical state. This transition,depending on thenumber of factors, can be smooth, but sometimes can cause relatively strong earthquakes that can disable industrial facilities and harm the environmentwith remote and unpredictable consequences. The aim of the project is to develop a methodology for using radar imagery data and mathematical modeling methods for geodynamic monitoring of mineral deposits located indifferent seismic and geological conditions. In 2017 to develop a system of complex geodynamic control of the state of the study areas and adjacent territory (geodynamic range). The methodological complex of monitoring observations involves setting the following activities: The SAR-interferometry method allows obtaining area estimates of vertical and planned displacements of the earth's surface with accuracy up to the first millimeters regardless of the conditions of illumination and cloudiness. Most effectively it can be used to control the development of deformation processes at hydrocarbon production sites, to detect subsidence in soils in coal mineareas, in areas of high seismic activity, and in cities with high-rise buildings or potentially dangerous ecological disasters (hydroelectric powerplants, nuclear power plants, etc.) Depending on the tasks, themethod can be applied both independently and in combination with geodetic (GPS,ground leveling) and geophysical methods, in particular, seismological methods. The method of mechanical and mathematical modeling, which allows creating parametric models on the basisof experimental data that give a real idea of the distribution of density in homogeneitiesand parameters of the strained deformation state in the Earth's crust. The newest methods of processing remote sensing data and geophysical methods (ASTER-technology, studyof thermal field anomalies, volumetric modeling of geophysical fields, terrainstudy, complex interpretation of geological, geophysical and aerospace data, etc.). The proposed set of methods is non-alternative. There are no critical points, except for the riskassociated with incomplete or unreliable initial (experimental) data. The technology in its research part is original, as it relies on the methods of research patented bythe authors. On the other hand, the scientific and practical novelty of the proposed works is to develop ageodynamic justification for a system of continuous monitoring of the development of geodynamic processes and ensuring the environmental safety ofmining facilities, including the regions of their location. The initial data is radar images on the territory of the Khromtau and Tengiz fields, for the period 2014-2015.With a resolution of 3 m, scene size of 30x50 km and HH polarization. Obtained results have amultiplier effect, since in addition to these benefits, they ensure the normal functioning of various economic facilities located in these territories andensure the normal residence of the population in cities with high-rise buildings. The significance of the project is that results are aimed at developing knowledge of the mechanism of geodynamic processes, which in turn, will contribute to increase economic and environmental safety at the sites of extraction of solid minerals both in the territory of Kazakhstan and beyond. This is important both for Kazakhstan,due to producing large number of minerals, and at international level, as man-made earthquakes related to mining objects are registered around the worldand in some cases can lead to significant destruction of industrial facilities,Agricultural lands and loss of population. Financing will be made on the basis of governmental budget funds.
