Reducing environmental impact caused by mining activities in limestone mines
Radmila Gaćina, Bojan Dimitrijević (2022)Mining and its related activities have always resulted in changes in the environment and these changes can vary from one area to another. As a result of mining, several types of changes can be distinguished: destruction of land and existing vegetation, changes in terrain topography, modification in air quality, changes in surface and groundwater quality, as well as change geotechnical conditions of the rock. Environmental impact of mining have been a public concern. There is widespread global interest in mining ...Radmila Gaćina, Bojan Dimitrijević.

Application of the principle of circular economy to the thermal groundwater, the example of the municipality of Bogatić
There are about 360 locations of thermal and thermo-mineral waters in Serbia, whose water temperatures range from 14 to 98°C, which ranks Serbia as the richest European country in geothermal energy. The mentioned water resources (thermal and thermomineral waters) are used, mostly, for therapeutic purposes in spas and sports and recreational centers. The main problem that is present is the fact that they are not used in a rational and efficient way. The paper will give examples territorially related ...Marija Jovanović, Vesna Ristić Vakanjac.
