Abstract. Annotation. The study of concentrations of toxic and potentially toxic elements (TPTE) in coal seams of the Pavlohrad-Petropavlivka geological and industrial district is caused of the strengthening of environmental protection requirements. The relevance of such studies is determined by a number of Laws of Ukraine, Cabinet of Ministers resolutions, and requirements of State Commission for Reserves to the quality and content of geological materials for exploration of coal deposits. As a result of the performed studies, dendrograms of the results of clustering by the weighted centroid method of the coal seams of the Pavlohrad-Petropavlivka geological-industrial district on the content of TPTE in coal were constructed. Scientific and practical interest is the classification of the main coal seams of the district for the content of TPTE in coal. In this connection, the task in this work was to establish the usual fragmentation of coal seams into classes that are free from subjectivism of the researcher. The aim of the work was to distinguish groups of homogeneous objects (classes, clusters, taxons), similar to each other, with a sharp difference between these groups from each other.
Keywords: Keywords: toxic and potentially toxic elements, dendrogram clustering, coal seam.
