“…Quarrying conducted on carbonate rocks, especially at plateau margins, valley sides, and small mountain summits, can lead to the destruction, shortening, or opening of existing caves. In Hungary, notable examples include the phreatic or former phreatic cavities uncovered during mining activities on Mount Esztramos [42] (Figure 2) and in the Bükkösd area of the Mecsek Mountains [43] (Figure 3). The formation of breccia pipes, a phenomenon observed in evaporite environments, is characterized by a process of mutual dependence between dissolution and collapse.…”

This investigation delineates the impacts of mining on karst systems, with a focus on specific karst zones, namely the epikarst, the vadose zone, and the phreatic zone, which includes the epiphreatic zone. Mining activities, regardless of the karst area type, predominantly affect these zones. When mining occurs at the surface or within the epikarst, it results in the destruction of surface features and the disruption of the epikarst, thereby locally halting karstification processes. The extraction in the vadose zone can lead to surface alterations, characterized by collapses, the formation of depressions, and the modification of epikarst activity, ultimately impacting surface karstification and inducing atectonic changes on the surface. The exploitation of the phreatic zone is associated with the artificial lowering of the karst water table and the removal of materials from cavities and depressions. This study emphasizes the importance of understanding the zone-specific impacts of mining on karst systems, highlighting the need for tailored conservation and management strategies to mitigate these effects. The findings contribute to the broader understanding of karst dynamics and provide a foundation for future research on the sustainable management of karst environments in the context of mining activities.

“…Under superficial unconsolidated (?) deposits, the bedrock became karstified to a various degree and in different periods (Mindszenty & Sebe, 2022), which resulted in the development of terrains with dolines (Bíró, 1969), and poljes (Szabó, 1956).…”

The epikarsts of five covered karst areas in the Bakony region are compared. The comparison is based on the specific resistances of the bedrock resistance averages measured by vertical electrical sounding (VES). The average largest specific resistance differences (per area) and the mean values (per profile) were calculated to investigate the characteristics of the epikarst. The mean values of specific resistance were compared using analysis of variance (ANOVA) to determine whether the specific resistances of the areas showed significant differences. The studied karst areas can be categorised as high or low specific resistance areas, and the ANOVA method could be applied to three areas based on the available data. It can be concluded that the mean values of their specific resistances are significantly different. The mean values and standard deviation of the specific resistances of the different areas were analysed. It is described that the karst receives less water in the case of areas with lower specific resistance, while it receives more water in the case of areas with higher specific resistance. Areas with a high specific resistance are less karstified, while areas with a low specific resistance are more karstified. Low specific resistances and small mean values indicate a higher degree of cavity formation in the epikarst, while the decrease in mean values and standard deviation indicates increasing uniformity of the degree of cavity formation in the epikarst. The different degree of cavity formation is explained by the different karstification rates and the exposure of different time of certain areas.

“…The paleokarst of the Bakony Region is borne by the peneplain that developed during tropical karstification [5]. Its paleokarst is mainly of Cretaceous age [6,7], but others may also occur [6]. The surface karst features mostly developed on Triassic dolomite; the cover is most frequently Eocene limestone and Middle Oligocene-Lower Miocene gravel [6].…”

This study describes the direct and indirect effects of mining on the karst of the Bakony Region. For this, the results of geological and mining research of the last century, the results of hydrological research of fifty years, as well as the investigations of several decades on the karst of the mountain region are used. Direct effects include the exploitation of filling materials (limonite, kaolinite, manganese ore, and bauxite) from paleokarst features, dolomite rubble, activities exploring or destroying cavities, and the pollution of cavity systems with mining waste (dirt). An indirect effect is karst water extraction. Mining activities (coal and quarrying) resulting in the development of pseudokarstic features are also mentioned here. It can be stated that the effects on the karst and karst features may be permanent and even renewing, but the original state may also have returned or can be expected in the near future. Damages may be local or regional. A regional effect is the decrease in karst water level, which has the most significant effect on the environment, but it has already reached its original state by now.
