Utilizing sewage wastewater heat in district heating systems in Serbia: effects on sustainability
Marija Živković, Dejan Ivezić (2021)Transformation of the heating sector is recognized as being essential for ensuring reliable and afordable energy services provided with reduced consumption of energy sources and diminished impact on the environment and less import dependency. The possibility of utilizing energy sources that otherwise would be wasted needs to be considered and treated as a big advantage of district heating systems. Despite many advantages, sewage wastewater heat is still a mostly unused resource at the global level and a totally unused ...рекуперација топлоте из отпадних вода, систем даљинског грејања, топлотне пумпе, енергетске уштеде, емисија угљендиоксида, енергетска безбедност, Србија... the preparation phase and WWTP loca- tion selection.

Fuzzy Model for Risk Assessment of Machinery Failures
The main goal of this research was the development of an algorithm for the implementation of negative risk parameters in a synthesis model for a risk level assessment for a specific machine used in the mining industry. Fuzzy sets and fuzzy logic theory, in combination with statistical methods, were applied to analyze the time picture state of the observed machine. Fuzzy logic is presented through fuzzy proposition and a fuzzy composition module. Using these tools, the symmetric position of the ...... al.

Application of the Fuzzy Model in the Evaluation and Selection of Hydraulic Excavators on Open-Pit Lignite Mine
Stevan Đenadić, Miloš Tanasijević, Vladimir Milisavljević, Dragan Ignjatović, Predrag Jovančić (2021)The production of lignite in large open-pit mines is mainly performed with continuously operating equipment, where bucket-wheel excavators, bucket-chain excavators, belt conveyors, and spreaders are the basic machines. Smaller machines, usually of discontinuous operating nature, are commonly categorized as auxiliary machines.

Legal framework for recultivation of degraded areas caused by mining exploitation
Radmila Gaćina (2023)Prilikom površinske i podzemne eksploatacije uglja eksploatacioni sistemi oštećuju veće ili manje površine zemljišta. Iskustva pokazuju da su oštećenja zemljišta znatno veća kod površinske eksploatacije, gde je prostora degradiran ne samo u konturi rudnika i okoline, već se promene takođe dešavaju u prirodnom okruženju. U članku su predstavljeni rezultati studije zakonskih okvira rekultivacije u nekim zemljama sveta i u Srbiji. Praktično iskustvo rekultivacije pokazalo je da iskorišćenje i devastacija tokom rudarske aktivnosti predstavljaju opasnost ne samo za pogođena ...... coal mining. Moreover, a good recultivation policy is a great way to introduce a restorative approach to the environment plus the sustainable management of reclaimed land.

The impact of temporal variability of groundwater levels on groundwater vulnerability maps in karst terrains – a case example of the Perućac spring catchment area
Groundwater vulnerability maps represent an essential tool for protecting karst groundwater resources. Vulnerability assessment is usually based on spatial evaluation of various parameters that affect the vulnerability degree and regulate the protection role of the unsaturated zone. Most of these parameters, like soil and geology conditions, are constant and do not change during the year or over several years. In contrast, some parameters, such as the groundwater level, depend on the variability of recharge conditions. By considering the variability ...Vladimir Živanović, Igor Jemcov, Nebojša Atanacković.

Hydrochemical indicators of groundwater flow in the area of “Čukaru Peki” Cu-Au underground mine in eastern Serbia
The physical and chemical properties of groundwater, together with the groundwater levels regime and rock hydraulic properties, are often used to understand and conceptualize the hydrogeological system. Prediction of the influence of mining works on groundwater, and vice versa, is a challenge due to significantly altered groundwater flow patterns in the raw materials exploitation areas in relation to natural conditions. Therefore, multiple parameters are assessed and monitored before and during exploitation to properly characterize and quantify the system for ...Nebojša Atanacković, Vladimir Živanović, Jana Štrbački, Veselin Dragišić, Ivana Cvejić.

Preliminary impact assessment of No2 emission from a heating plant on air pollution: case of Zemun, Serbia
The aim of this paper is to provide a preliminary evaluation of the impact caused by NO2 emissions from a heating plant on the local air quality. To model the spatial distribution of NO2 emissions from the heating plant, the AERMOD model was employed. The evaluation was conducted by analyzing and contrasting the simulated NO2 concentration from the heating plant with the overall NO2 concentration recorded at the nearest monitoring station over the entire heating season. The study focused ...Boban Pavlović, Uroš Pantelić, Marija Živković, Dejan Ivezić.
