Zmienność mineralizacji wód dopływających z poziomu wapienia podstawowego do wyrobisk górniczych kopalni Rudna KGHM

Abstract

Mineralization variability in waters flowing from the Basal Limestone to the Rudna KGHM mining excavations.A b s t r a c t . The article discusses the results of the work on the variability of water mineralization in the Basal Limestone, inflowing to the excavations of the KGHM Polska Miedź S.A. Rudna mine. The spatial variability of the total water mineralization and concentrations of particular ions (Na+, Cl–, SO42+, Ca2+ and Mg2+) were analyzed. It has been observed that the mineralization of waters from theBasal Limestone is from 12 to 256 g/dm3 with a mineralization gradient at 43.34 g/dm3/100 m. The waters are of the Na–Cl chemical type. It was found that the lowest concentrations of Na+ and Cl– characterize the southern part of the study area. Concentrations of these ions increase in the northern part of the Rudna mine, where the lowest content of sulphate ions and the highest concentrations of Ca2+ ion were observed. Based on selected, most commonly used hydrochemical indexes, an attempt was made to determine the origin of the major ions.
