Hydrogeological foundations of the usage of depleted pits areas

Abstract

The problem of choosing the type of activity, methods and technologies of reclamation of quarry spaces, in the conditions of minimizing the harmful impact on water resources, is determined by a large number of natural and man-made factors. One of the main and determining factors is the state of surface and groundwater, as well as their change in the reclamation of quarries. To solve this problem, it is proposed to create an information and expert system (IES) for selecting a method of reclamation of quarries of IES «Quarry-water-reclamation», based on the natural and man-made conditions of the territories. The purpose of the development of IES «Quarry-water-recultivation» is a reasonable choice of methods, options and technologies for recultivation of the quarry space, based on the physical, geographical, geological, hydrological and hydrogeological conditions of the research area, the method of mining, the conditions of use of surface and groundwater, on the basis of these monitoring systems, as a result of retrospective and predictive geofiltration modeling, taking into account the planned for the implementation of design and water protection solutions and measures, as well as the social - economic conditions of the region. Tasks for the collection and compilation of physicogeographical, geological, hydrological and hydrogeological conditions according to the basin principle, the characteristics of economic activities, the construction of geofiltration, hydrodynamic and computational models, with the further correction of the last solution of the series of predictive tasks, the change of the hydrological and hydrogeological conditions of the area as a result of various variants of recultivation of the quarry, analysis of the current legislation, the requirements of the local authority and wishes of the local people, development of the project of water protection measures of the selected option.
