“…Much attention is paid to the study of filtration-deformation processes occurring in the enclosing tailings dam and determining its reliability [2,[7][8][9]. At the same time, one of the main tasks of research in order to ensure the filtration stability of the enclosing tailings dam is to assess the degree of water filtration through its body at different positions of the depression surface of groundwater in the tailings dam HTS [10][11][12][13][14][15].…”

Scenario hydrogeomechanical 3D modeling of groundwater filtration through the body of the enclosing tailings dam of a mining enterprise was carried out. A hydrogeomechanical 3D model of the tailings dam was created and modeling of filtration-deformation processes was carried out according to three scenarios for the position of the depressed surface of groundwater: the actual state, the limit according to the project, and the maximum filling with water. The calculated values of the rate of water filtration through the body of the enclosing dam are determined for the simulated scenarios of the position of the depression surface. A graphical dependence of the filtration rate on the position of the depression surface of groundwater is revealed, and an analytical expression approximating it is found.

“…6). В качестве примеров полученных результатов можно привести: оценку фильтрационной и механической устойчивости ограждающих дамб, локализацию переувлажненных зон грунтов и формирующихся фильтрационных каналов, выявление механизма инфильтрации и формирования зон механической суффозии [5]. На карьере рудника «Железный» Ковдорского ГОКа был определён механизм инфильтрации воды из накопителя промышленных стоков, реализующийся в формировании зон повышенных водотоков в насыпной ограждающей дамбе, с выходом на рабочий борт карьера [3].…”

The relevance of research, diagnostics and study of natural and technical objects belonging to I–II hazard classes is shown. Methodological approaches to the application of interdisciplinary methods for a complex of observations and observation of such objects are proposed: visual observations and photodocumentation, geophysical survey, hydrological measurements, geomechanics methods, satellite geodesy, digital photography using UAVs, remote sensing, hydrogeomechanical modeling. Comprehensive natural observations of various incidents on the earth's surface: underground, explosive, high-altitude and satellite. The underground level includes hydrological measurements, seismic tomography and georadar sounding. At the surface level, geodetic surveys, horizontal and vertical measurements, geodetic referencing and precise positioning of objects are performed. Various types of digital aerial photography are used for the high-altitude level. The basis of the satellite level is the processing and analysis of multispectral and radar images (ERS). The data obtained as a result of field studies are used to develop hydrogeomechanical 3D models, with the help of which scenario modeling of various hydrogeological and geomechanical conditions is performed. Such an approach to solving monitoring problems, which consists in integrating interdisciplinary studies at various levels, makes it possible to control a natural and technical object in a hierarchy: from a structure as a whole to its individual structural elements and local sections. A description is given of examples of the application of multilevel integrated research and monitoring of natural and technical objects of mining enterprises in the Kola region.
