The Sztoła River crosses Lesser Poland and Silesia voivodships in the region of Olkusz zinc and lead ores mining and sands extraction. It is one of the left-bank tributary of Biała Przemsza. Its sources are located southwest of Olkusz. In the geological structure of Sztoła water catchment area, on the basis of conducted drillings, the following deposits can be distinguished: Paleozoic, represented by Permian deposits, Mezozoic-Triassic deposits, and Cenozoic-Quaternary deposits (Buła 2000, Motyka 2010). Hydrodynamic conditions in the region of Sztoła have been strongly interrupted by the development of zinc and lead ores mining and a sand pit, which required an application of drainage. The first system of drainage was adits built in 16 th century, which resulted in a decrease of the groundwater table level from few to over a dozen meters (Żukowski 1946, Górnisiewicz 1975, Molenda 1977, Kosiński 1882). The intensive development of mining in this region began in the first half of 19 th century, along with appearance of new drainage techniques. The Sztoła River changed its character from draining to infiltrating on its the whole length as the effect of development of vast zinc and lead ores mine depression cone, related to the exploitation of the „Pomorzany” mine, and later with a gravitational drainage of sandpit „Szczakowa” (Witczak & Motyka 1975, Haładus et al. 2007). In the upper part of the river it resulted with a partial dry out of the riverbed. Water flowing in the river originated from the drainage of Olkusz zinc and lead ores mines and is directed there through Baba channel. A research conducted in the summer of 2014 examined the upper part of the Sztoła River. Groundwater taken from springs, as well as surface water, was collected, and the areas of critical riverbed dry out were identified. A complete physicochemical analysis was carried out in the AGH hydrogeochemical laboratory in Cracow. On the basis of the received data, the characteristics of chemical composition of groundwater and surface water were prepared. Their hydrochemical type, pH values, electrolytical conductivity was determined. Chemical composition was also presented in the selected graphical forms (Piper, Collins, Pie Chart). Based on analysis, the statistical parameters of composition of water from the research region were calculated. Furthermore, the quality of underground and surface water was evaluated according to the existing standards, and suitability to consumption by people was determined. The Obtained data were also compared with archival results of samples collected within the investigated area.

Planowanie i zagospodarowanie przestrzenne wymaga uwzględniania uwarunkowań wynikających z przeprowadzonej eksploatacji górniczej. W przypadku wielu rejonów zagłębia śląsko-dąbrowskiego ich ocena jest trudna, co wynika przede wszystkim z długiej historii górnictwa. W artykule scharakteryzowano mapę, opracowaną dla miasta Jaworzno, której treścią są te elementy, które mogą stwarzać zagrożenie dla obiektów zagospodarowania powierzchni. Należą do nich wyrobiska mające kontakt z powierzchnią oraz dawna eksploatacja odkrywkowa i podziemna prowadzona na małych głębokościach. Ponadto określono sumaryczną miąższość wybranych pokładów węgla kamiennego.

Planning and spatial management require to take into consideration the conditionings resulting from performed mining exploitation. In conditions of many regions of the Silesia-Dąbrowa coal basin their assessment is difficult, what results first of all from the long history of mining. In the article a map was presented, prepared for the city of Jaworzno, containing these elements, which can create hazard for objects of surface management. There belong to them excavations having contact with the surface and previous opencast and underground exploitation conducted at low depths. Moreover, the total thickness of mined out hard coal seams was determined.

Stosowana obecnie technologia oczyszczania wód kopalnianych z kopalń rudnych rejonu bytomskiego pozwala na pozyskanie wody dopuszczonej do zrzutu do odbiorników powierzchniowych oraz szlamu odpadowego. Wadą obecnie przyjętego rozwiązania jest wysokie stężenie jonów SO4 2- w wodzie doprowadzanej do środowiska i zmienność składu wydzielanego osadu. Wady te ograniczyć można stosując, w zmodernizowanej technologii, strącanie siarczanów glinowo-wapniowych i dwuetapowe osadzanie produktów koagulacji wapnem. Przedstawiono możliwości prowadzenia oczyszczania wód zrzutowych górnictwa rud Zn-Pb jako procesu bez powstawania odpadu. Wskazano na właściwości szlamu wydzielanego podczas oczyszczania, które kwalifikują go jako substytut drobno mielonego wapienia. Omówiono warunki i możliwości wykorzystania szlamu.

The used at the present time technology of purification of mine waters from ore mines in the Bytom region allows to obtain water admitted for discharge into surface receivers and waste sludge. The fault of the currently adopted solution is high concentration of SO4 2- ions in the water conveyed into the environment and variability of composition of the released sediment. These faults can be limited using, in the modernized technology, precipitation of aluminium-calcium sulfates and two-stage deposition of coagulation products by means of lime. The possibilities of purification conducting of discharge waters of Zn-Pb ore mining as a process without waste generation were presented. The properties of sludge released during purification, which qualify it as a substitute of fine-grained limestone, were presented. The conditions and possibilities of sludge utilization were discussed.
