Strategic Environmental Assessment in the Application of Preventive Protection for Wind Farm Noise—Case Study: Maestrale Ring Wind Farm
Determining the spatial position of wind turbines is the initial and most important phase in the development of a wind farm project. In this sensitive phase, all potential problems that may arise in the later stages of project development should be prevented by means of spatial and urban planning instruments. This makes it possible to achieve maximum use of the potential of wind in a particular space and, thus, fulfil the technical and economic requirements of the project while ...Energija,energetski inženjering i elektroenergetska tehnologija,obnovljivi izvori energije, održivost i životna sredina,električni i elektronski inženjering,kontrola i optimizacija,inženjering... farm project.

Просторна анализа епикарста у оквиру карстног система источног дела Суве планине
Епикарст представља највиши део стенске масе који је изложен карстификацији, при чему су главне карактеристике епикарста акумулирање подземне воде и стварање услова за формирање концентрисаних токова у подини ове зоне. У досадашњој пракси истраживања епикарста углавном су коришћене индиректне методе: даљинска детекција, анализа хидрограма карстних врела, хидрохемијске и изотопске анализе, па чак и опити трасирања, док је са друге стране јако мали број истраживача изучавао епикарст директним теренским истраживањима.

Regional rockfall exposure assessment, experience from Serbia
Rockfalls are common in hilly and mountainous areas, especially along roads with engineered slopes and cuts. Such is the case for most of the state and local road routes in Central, Serbia, which was the subject in this case study. A road network of 276 km covering roughly 1700 km2 between the cities of Kraljevo, Čačak and Ivanjica is presented. Assessing of such wide areas needs to be conducted from large to site-specific scale, i.e., using GIS spatial tools ...Miloš Marjanović, Biljana Abolmasov, Uroš Đurić, Jelka Krušić, Snežana Bogdanović.

Self-Engineering: Possibilities for Maintenance Operations in the Mining Machines Industry
Self-engineering is a relatively new branch of knowledge that aims to understand how systems could “autonomously” re-configure or repair themselves without the intervention of the operators. A direct field of application is within the maintenance spectrum. Having systems or machines capable of self-detecting or even self-repairing could represent a game-changer, in capital asset fields such as the mining industry in particular. This paper aims to investigate the possible benefits and challenges of self-engineering / self-maintenance concerning mining machines, specifically bucket-wheel ...self-engineering, self-maintenance, maintenance operations, mining industry, bucket-wheel excavator, gearbox revitalizationSteven Manders, Milorad Pantelić, Vladimir Milisavljević, Alberto Martinetti.

Proučavanje razvića Bihaćkog i Cazinskog basena primenom gravimetrijskih podataka
Bihaćki i Cazinski baseni su neogeni baseni, koji pripadaju spoljašnjim Dinaridima i formirani su tokom kasne faze razvoja Dinarida. Ovi baseni su od posebnog interesa zbog svoje geološke prošlosti i potencijalnih strukturnih karakteristika. U istraživanju, primenjeni su gravimetrijski podaci u clju boljeg razumevanja evolucije ovih basena. Primenom različitih postupaka matematičkih transformacija na gravimetrijskim podacima može se ustanoviti gravitacioni uticaj neogenih basena male gustine i mogu se detektovati strukture, koje su potencijalno vezane za njihovo formiranje.

Geoheritage and Mining Heritage in the Promotion of Theme Parks: An Example of the National Park Đerdap (Carpathian-Balkan Thrust-And-Fold Belt, Eastern Serbia)
The National Park Đerdap (eastern Serbia, vicinity of the Danube River) occupies a segment of the Carpathian-Balkan fold-and-thrust belt and has a significant geoheritage potential, accounting for the impressive natural (geological) and cultural legacy. In addition to the extraordinary orogenic-type landscape or nappe-stacked mountainous configura tion, the region contains evidence of ancient mining activities, uncovered within its immediate neighbourhood. The ancient mining activities date back a few thousand years ago and represent a solid ground for the idea of ...Karpatobalkanski pojas nabora i navlaka, Geopark Djerdap, Tematski park "Muzej rudarstva", Konzervacija, Održivi razvoj, Geotopi, SrbijaIvana Mojsić Velikić, Dragoman Rabrenović, Danica Srećković-Batoćanin, Darko Spahić.

Ground surface subsidence monitoring using sentinel-1 in the “Kostolac” open pit coal mine
Zoran Gojković, Milan Kilibarda, Ljiljana Brajović, Miloš Marjanović, Aleksandar Milutinović, Aleksandar Ganić (2023)Open pit coal mining affects surrounding populated areas, resulting in terrain surface deformation. Surface deformation should be monitored as often as possible to control deformations and prevent potential incidents. This paper analyzes time series deformation estimated from the Sentinel-1 satellite images using the Persistent Scatterer Interferometry method to monitor subsidence rates caused by open pit mining activities. It is possible to measure deformations using classical geodetic methods, but those are rarely used in practice because they are time-consuming and ...Zoran Gojković, Milan Kilibarda, Ljiljana Brajović, Miloš Marjanović, Aleksandar Milutinović, Aleksandar Ganić.
