GIS-Based Subsurface Analysis and 3D Geological Modeling as a Tool for Combined Conventional Mining and In-Situ Coal Conversion: The Case of Kardia Lignite Mine, Western Greece

The development of three-dimensional geological models has proven to be critical for conceptualizing complex subsurface environments. This is crucial mining areas due their various hazards and unstable conditions. Furthermore, (3D) can the initial step numerical in order support decisions sustainable planning. paper illustrates results phases a 3D model within boundaries Kardia lignite deposit western Macedonia, Greece. It also highlights usefulness Geographic Information System (GIS) methodology hydrogeological analysis regarding Underground Coal Gasification (UCG) methodology. In addition, work focuses on integrated geospatial framework that was developed Coal-to-Liquids Supply Chain (CLSC) integration unfavorable settings. A study area identify suitable situ coal conversion UCG considering criteria related specific thickness depth. this context, suggested geomodelling workflow positively contribute implementation conventional innovative mining, saving time reducing cost improve quality information needed implementation.
