In this article the technological process of creation of 3D modern conceptual digital models of hydrogeological objects and processes is considered. The technology of 3D modern conceptual digital modeling of hydrogeological objects is presented. The technology involves such processes as: actualization of digital elevation model, digital hydrogeological schematization and stratification, formation of relational databases of structural elements of models, creation of digital 3D-frames and volumetric solid representations of hydrogeological subdivisions. The construction technology of isosurfaces of chemical components is also presented, which includes: formation of digital database of chemical components, statistical analysis of values, justification of methods and parameters of interpolants construction, construction of 3D-isosurfaces of interpolants, visualization of 3D-isosurfaces of interpolants.The software systems of 3D dynamic conceptual modeling of hydrogeological objects in the influence zone of SGOK showed high efficiency due to the rapid formation of conceptual hydrogeological models with regard to the current surface relief formed by the quarry, rock dumps, tailings pond and other hydraulic facilities. The boundaries of the aquifers and impermeable strata are traced, and the multivariant construction possibility is demonstrated. The modeling results of the isosurfaces and solid components in the qualitative composition of groundwater in 3D format allows their spatial visualization, morphometric analysis, volume estimation and other studies ensured by capabilities of 3D modeling.
