Quality assessment of reclaimed disposal areas of strip mines, by example of Piaseczno Mine dump
(2010) Bykov, Roman; Eckes, Teresa; Trafas, Maria
The present paper aims to perform a detailed analysis of all available results of physical and chemical testing of recultivated land, in order to determine which of them significantly influence their quality, and should thereby form the basic criteria for the evaluation and for the development of the methods of management of lands subject to recultivation. The samples of soil from Piaseczno dump area were tested. The test results have allowed to state that the method proposed by Gruszczyński, based on the physical properties of soil, with special respect to the water and air properties and sorption abilities, allows to properly evaluate the quality of such soil. The method allows also to take account of changes in soil quality, occurring as a result of the soil-creation process initiated by the recultivation.

Statistical Analysis of Soil Contamination in Vicinity of Coal-Processing Plant: Implications for Ecosystem Stability
(Wydawnictwa AGH, 2025) Kochmar, Iryna; Karabyn, Vasyl
The extensive generation of waste and intensified geological processes that result from hard coal mining and active operations within mining regions have led to increases in the pollution levels of ecosystems. Most coal-mining wastes contain significant amounts of heavy metals and are, therefore, particularly hazardous to the environment. The soils around waste heaps can be contaminated with various pollutants. This article presents the results of a study of soils that were sampled in the impact zone of the waste heap of the Chervonohradska CPP of the Chervonohrad Mining District. Using statistical methods (including variogram modeling and spatial interpolation), we analyzed the spatial distributions of heavy metals in the affected soil zones. This approach allowed for an enhanced understanding of contamination-dispersion patterns and potential risk areas. The authors collected soil samples from the depth of the biotically active humus-accumulative horizon from the lower tier of the slope of the waste heap at distances of 20 m, 40 m, and 100 m from the spoil tip. We measured the contents of the studied elements in the soil using X-ray fluorescence analysis and assessed the quality of the soil by phytotesting using the Triticum aestivum L. and Lepidium sativum L. test species. It was found that the average concentrations of certain heavy metals in multiple samples exceeded the background values for the region and affected the inhibition of the development and growth of the test objects.

The analysis of the patterns of land classification in terms of the application in the valuation of soilless areas
(2008) Gruszczyński, Stanisław
Celem podjętych badań jest określenie zasad transformacji istniejącej tabeli klas gruntów na zbiór reguł lub algorytm obliczeniowy pozwalający na oszacowanie bonitacji gruntów pozbawionych podstawowych atrybutów klasyfikacyjnych. Głównym problemem jest określenie relacji możliwych do oznaczenia cech glebowych do pozycji w szeregu bonitacyjnym. Trudność wynika z różnorodności pochodzenia tworzywa mineralnego rekultywowanych obiektów: od surowych gruntów do materiałów technogennych. W poszukiwaniu odpowiedniego modelu wnioskowania przebadano kilka algorytmów klasyfikacji i regresji.
