The purpose of the study was determining of degree of contamination of soil cover as a result of disposing of different industrial wastes and comparison of the soil quality with quality of soils and the grounds described in standards in relation to the reclamation works carried out on the dump. Analysed waste dump belongs to the sparse objects of this type in the Upper Silesian Coal Basin, where both coal mining wastes as well as flying ashes occur. During investigations there was done a collection of 9 soil samples around the dump using Egner`s cane from the depth of 30 cm. The content of heavy metals was determined (Cd, Co, Cr, Cu, Ni, Pb, Zn) using method of emission spectrometry (ICP-AES) and phase composition studies using the X-ray diffraction method (XRD). Obtained results enabled determination of impact of disposed wastes on the degradation of pedosphere of studied area, which represents III group of fallow lands. The contents of heavy metals in soil samples vary in wide spectrum, but do not exceed permissible content of metals and metalloids for the aforementioned soil group. The highest concentrations reaches iron (average content 0,6%), while concentrations of other elements do not exceed 0.02%. In the mineral composition of soil samples the dominant components are typical for soils in the area of post-mining dumps, i.e. quartz, feldspars, clay minerals, represented by kaolinite and illite. The presence of muscovite with a share of < 5% was also found. Minerals from the carbonate group – calcite (< 3.5%) and dolomite (< 0.3%) occur rarely. In the investigated samples there was identified presence of mullite, component typical for wastes coming from energy sector.
