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.

Damage quantification of built stone on Dark Gate (Belgrade, Serbia): sample of damage index application for decay rate evaluation
The Dark Gate is the monument of culture, part of the cultural and historical complex of the Belgrade Fortress. It is constructed of limestone blocks that after 270 years of exposure to environmental conditions and different anthropogenic influences show wide ranges of decay forms. During 2007, detail registration of all built limestone microfacies and weathering forms was done using tools of monument mapping. A correlation scheme ‘‘intensity– damage category’’ was made according to the type, intensity, and distribution of ...... demands, lack of maintenance, and inappropriate past treatments present challenges for the conservation of stone buildings, structures and objects.

Using gravity data to define structural correlation affecting the formation of Neogene basins
A gravity survey can help to define the structural correlation in the study area. The structures that have influenced the development of Neogene basins can be defined using gravity data. By applying mathematical transformations to gravity data, the geological structures (faults, nappes, etc.) that impacted the formation of Neogene basins can be defined.
