The objective of the study was the analysis of trace elements contents in coals of the Upper Silesian Coal Basin (USCB), which may pose a potential threat to the environment when emitted from coal processing systems. Productive carbon overburden in central and southern zones of the USCB is composed mostly of insulating tertiary formations of a thickness from a few m to 1,100 m, and is represented by Miocene and Pliocene formations. In the data study the geological conditions of the coal seams of particular zones of the USCB were taken into account and the hierarchical clustering analysis was applied, which enabled the exploration of the dissimilarities between coal samples of various zones of the USCB in terms of basic physical and chemical parameters and trace elements contents. Coals of the northern and eastern zones of the USCB are characterized by high average Hg and low average Ba, Cr, and Ni contents, whereas coals of southern and western zones are unique due to high average concentrations of Ba, Co, Cu, Ni, and V. Coals of the central part of the USCB are characterized by the highest average concentration of Mn and the lowest average concentrations of As, Cd, Pb, V, and Zn.
该研究的目的是分析上西里西亚煤盆地（USCB）煤炭中的微量元素含量，这些元素在煤炭加工系统排放时可能对环境构成潜在威胁。USCB中部和南部地区的生产性碳覆盖层主要由厚度从几米到1100米不等的绝缘第三系地层组成，以中新世和上新世地层为代表。在数据研究中，考虑了USCB特定区域煤层的地质条件，并应用了层次聚类分析，这使得能够从基本物理和化学参数以及微量元素含量方面探索USCB不同区域煤样之间的差异。USCB北部和东部区域的煤炭特点是汞平均含量高，钡、铬和镍平均含量低，而南部和西部区域的煤炭则因钡、钴、铜、镍和钒的平均浓度高而独特。USCB中部地区的煤炭特点是锰的平均浓度最高，砷、镉、铅、钒和锌的平均浓度最低。
