ABSTRACT
Diverse variants and methods of securing water-land environment against the impact of pollutants washed out from dumping ground located inside the open pit were considered within the model research works. A detailed analysis included conceptual models of reducing water flooding of the open pit, which were the basis for numerical model studies. Different concepts concerning the reduction of water inflow into the pit were considered at the simulation phase, including the inflow reduction by sealing the landfill plateau, construction of barriers or anti-filtration screens in various systems or application of a combined variant. The multivariate studies concerning the changes of hydrodynamic conditions within the area of the open pit were supposed to be the basis for the assessment of the numerical simulation studies reliability, their possibilities and influence on the selection of an optimal method of liquidation of the open pit and the best possible protection of underground water against pollution within its surrounding area.
