This paper addresses the issue of environmental noise from mining operations, focusing on the specific case of a quarry located in the municipality of Trebejov, Slovakia. The study aims to demonstrate an effective approach to reducing noise pollution through the implementation of mobile noise barriers. The research was motivated by the negative impact of noise from the processing line on the wellbeing of the population residing in the vicinity of the facility. The study involved conducting extensive noise measurements at various locations surrounding the quarry. The collected data were analyzed to assess the existing noise levels and identify the areas of highest noise exposure. Based on the findings, the implementation of mobile noise barriers was proposed as a solution. The results of the study demonstrated that the mobile noise barriers successfully reduced the noise levels below the legal limits, significantly improving the well-being of the population living near the quarry. The case study opens up the possibility of using mobile noise barriers in other areas and operations with high noise exposure. [ABSTRACT FROM AUTHOR]

The research has revealed that the increased mortality on cardiovascular and oncological diseases in the Krupina district, belonging among the most serious in Slovakia, is caused mainly by the low calcium and magnesium contents in the groundwater, being used for drinking by inhabitants of the Krupina district. The paper provides the research results of artificial mineralization tests for one model (distilled) water and two waters from the representative home wells from the Krupina district at standard parcial air pressure (CO2 ~ 0.03 vol.%.), as well as at increased CO2 concentration in the water in laboratory static and dynamic conditions, applying carbonatic rocks (dolomite, magnesite, limestone), as well as the half-calcined dolomite (HCD) in amounts of 10, 20 and 100 kg/m3 of the water and duration of mineralization process 1, 2, resp. 4 hours. The laboratory tests of the mineralization of the water have manifested that there is possible significantly increase the content of Ca and Mg in the water to values reaching, or even overreaching, the requested values for drinking water. The highest enrichment was obtained using HCD and it related to magnesium increase. However, the HCD application caused the decrease of the Ca content. Therefore, the limestone or dolomite must be also used in the mixture, so for water mineralization in the home wells we recommend using a mixture of limestone and HCD, where the HCD content in the mixture should be about 30%. No significant differences were found from the point of view of the grain-size of the carbonate rock used. The Ca and Mg contents increase with longer duration of mineralization process. The recommended amount of added rock is from 20 to 100 kg.m-3 of the water. The controlled addition of carbon dioxide to waters with deeply deficient calcium and magnesium contents when using dolomite (or half-calcined dolomite) at the amount of 20 kg/m3 causes a significant increase in the hardness and Ca and Mg concentrations in a relatively short time (up to 5 minutes) in mineralized water up to / above the recommended values according to the valid legislation.

This article presents a research study of complex limestone karst engineering‐geological conditions in the municipality Valaská near Banská Bystrica in Slovakia. The aim of the study is to demonstrate the impossibility of spatial identification of cave spaces using surface geophysical methods due to the specific engineering‐geological conditions of a thick surface layer of anthropogenic fill containing highly heterogeneous anthropogenic material. Its maximum thickness is 3 m. Another specificific condition of the study area is its location in the built‐up area, due to which the applicability of geophysical methods was limited. The article contains methodological recommendations to be used in analogous geological conditions with karst structures topped with anthropogenic fill, which complicates the identification of cave spaces. The recommended solution herein is the identification of the cave system using underground mapping of the karst and its projection onto the surface for which surface geophysical methods have been combined.
