ABSTRACT: Hydraulic regime of particular parts of flooding mining areas and its manifestation emerged from Darcy's approach to flooded inactive mines and stopes. Model solved vertical and horizontal discretization of modeled structure, determination of basic boundary conditions, quantification of input hydraulic parameters in modeled layers, inputs quantification for model balance equation, verification and calibration of model according to present knowledge, analysis of model outputs and variant simulation. Threedimensional quasistationary model on a definite differences numerical method basis has been used for mathematicai modeling. Computation has been calculated by verified MODFLOW software in GMS 2.1 environment.
