AP09058620 – Web-GIS development based on complex geodynamic monitoring data for LTD "Kazakhmys Corporation" deposit field

The main objective of the project: Ensuring industrial safety in the territory of the mining enterprise by conducting a complex monitoring of geodynamic processes and implementing the obtained data in the Web GIS format.

The relevance of the project: Currently, in many countries of the world there is an active use of radar data for monitoring purposes. In Italy, England, the Netherlands, USA, Germany, Japan, Switzerland, there is a progressive development and modification of the methods of analysis and interpretation of radar data. Developments in the field of radar interferometry in the United States are taking place within the framework of scientific work of the National Aeronautics and Space Administration (NASA), and in the European Union - ESA. As a well-known example of active use of radar data, one can cite the results of research work carried out before and after the famous earthquake that occurred in 2003. in the Iranian city of Bam. As a result of the processing of radar data, it was possible to assess serious changes in the earth's surface in the territories adjacent to the city and destruction in residential areas.

Results obtained: During 2021–2023, comprehensive geodynamic monitoring studies were conducted using precise leveling, GNSS measurements, and InSAR satellite data. Geological and geodetic data were analyzed, unstable zones were identified, and a geodynamic polygon consisting of 24 stations was established with baseline measurements performed. A geospatial database was developed, and surface displacement maps were generated. In 2022–2023, multiple GNSS measurement campaigns were carried out and validated against InSAR results, showing strong agreement. Deformation processes were analyzed, and displacement velocities and directions were determined for all monitoring points. A corporate WEB-GIS system based on PostgreSQL/PostGIS, QGIS, GeoServer, and OpenLayers was developed and implemented in production. The results enable accurate prediction of ground deformation, improved industrial safety, and more effective decision-making processes.
