<p>Geoheritage studies offer a novel perspective for the understanding of coal resources. The related scientific knowledge needs systematization. A major bibliographical database “Scopus” was employed to identify the principal sources of this knowledge published internationally. A total of 42 relevant publications (chiefly journal articles) were selected. It was established that this geoheritage was studied for more than two decades, but principally after 2010. About a third of the works were published in geoheritage-focused journals, but none appeared in any coal-focused journal. A half of the works dealt with existing geoheritage objects. The bibliographical survey implied that coal-related geoheritage can be attributed to many geoheritage types (chiefly sedimentary and economical, but also palaeontological, stratigraphical, engineering, tectonic, geomorphological, geochemical, mineralogical, and geohistorical types) and various geoheritage forms (for instance, quarries, underground mines, and natural outcrops, geoparks, and museums). Apparently, the analyzed studies were biased geographically (emphases on Europe and Asia) and stratigraphically (emphases on Late Paleozoic and the Cenozoic). Thematically, these studies were rather diverse, and paid significant attention, particularly, to sustainability and geotourism. Coal-related geoheritage studies demonstrate evident potential and their extension can benefit management of (post)-mining areas and diversify the overall international research in coal resources and geoheritage.</p>
