Podvigina E. Basing of Catchment's Parameters of the Mine Fields Geomechanicaly Disturbed in the Central Area of Donets Basin

Thesis concerns to substantiation of schemes and parameters of groundwater mode regulation on the basis of a method of mathematical modeling for decision making for geotechnical safe closing mines. The analysis of the hydrodynamic situation has shown that closing of mines by using "wet" conservation method leads to abnormalities in system "groundwater level - rocks", rising of underground waters level and underflooding, waterlogging, salinization of soil of Geoindustrial Districts. For studying of parameters of groundwater mode forming on the territory of the Central Geoindustrial District of Donets Basin regional mathematical model was created. The paleohydrodynamic situation was created on the regional mathematical model. Filtration parameters of rocks have changed at conducting mining work. Parameters of interaction of inviolate rocks and mine working were determined. Operating conditions and flooding of mines with the help of the model mechanism of hydrodynamic mode formation are determined and technological parameters of underground water mode management are proved. The analysis of technological schemes of groundwater mode regulation for geotechnical safe closing mines of the Central area of Donets Basin is given.
