The influence and amounts of groundwater inflow to the open pit limestone mine "Celiny” (Kielce region, southern Poland) were determined in this paper. Based on the collected data, a quantitative assessment of the groundwater bodies (GWB) Nos. 101 and 115 was conducted, and the range of the depression cone and the impact on water intakes operating in the vicinity of the mine were determined. The collectedfield and archival data were used to build a conceptual model, based on which a numerical model of the groundwater circulation system was developed using Visual MODFLOW software. The numerical model maps the five-layer groundwater circulation system in conjunction with surface watercourses. The external boundary of the 130 km2 model area (divided into square grids of 50 m) was based mainly on watercourses and locally on watersheds. Computer simulations (15 in total) were carried out for three hydrodynamic conditions related to the multi-year (1951-2015) precipitation: average, dry and wet, for three ordinates of the open pit drainage: 241.5, 230.5 and 219.5 m a.s.l. and a diverse exploitation status of the existing groundwater intakes, and taking into account the open pits operating in the research area. The results show that the designed drainage of the open pit mine will not have a significant impact on the quantitative status of the adjacent GWBs.

Model investigations were performed to determine the groundwater circulation system in the catchment area Andrzejówka and Milik streams. The results of these studies allowed to assess the renewability of groundwater resources. Documentation of disposable resources was prepared in the separate units water balance area for fresh and therapeutic water. These measures allowed to define the conditions of groundwater use in the analyzed area. This object was achieved through the development of a multi-layer mathematical model using the software package “Visual MODFLOW”, v. 4.3. According to the authors, the main advantage of the model is its ability to provide a coherent concept for the conditions of circulation and exchange of water with using most of the available direct and indirect data. The model in this present form is suitable for regional assessment of water circulation conditions including more than ever precise definition of renewable and disposable resources and water management balance, both fresh and therapeutic water.
