Control of substructure construction of railways in the Republic of Serbia
Контрола збијености природног тла (у ископу) или збијеног у насипу при изградњи саобраћајница представља један од основних облика контроле квалитета доњег строја. Код изградње брзих саобраћајница (аутопутеви и брза железница) приоритет је постизање високог нивоа контроле извршених радова. У циљу онемогућавања диференцијалног слегања (при изградњи насипа), или промене запремине услед допунског збијања материјала, које неминовно доводе до деформација, потребно је извршити оптимално збијање материјала. У оквиру овог рада приказује се техничка регулатива која регулише контролу збијености при изградњи железничке ...Dragan Lukić, Dragoslav Rakić, Irena Basarić Ikodinović.

Overview of the hydrogeological investigations of recently discovered world class deposits in Serbia
Europe industry has growing concerns on availability of the raw materials. To address this challenge, the European Commission has created a list of critical raw materials for the EU, launched EIT Raw Materials initiative, and continuously support research projects (like INTRAW, UNEXMIN etc.) with the aim of reducing the dependency and meeting growing demands. In the last 15 years Serbia is experiencing new bust in geological exploration of mineral deposits. Currently 167 exploration licenses are active, covering approximately 6000 ...Nebojša Atanacković, Vladimir Živanović, Veselin Dragišić, Sava Magazinović.

Complex geophysical survey on solving the problem of water loss in the karst terrain reservoir
Branislav Sretković, Dejan Vučković (2023)Geophysical surveys in karst terrain are always a specific challenge. Each of them requires a careful consideration of the problem, specific conditions on the ground, the selection of adequate methods applicable in that specific and unique karst area. But they should have one thing in common: a complex approach and looking at the problem from wider to narrower, with a gradual narrowing of the investigation area, increasing the spatial precision and resolution of the obtained data. On the example of ...Branislav Sretković, Dejan Vučković.

Challenges and Insights: Sequence Stratigraphy of Pannonian Coals in the Drmno Depression, Serbia
The application of sequence stratigraphy on coal beds worldwide has significantly contributed to the under¬standing of coal deposits and their origin. On the southeastern edge of the Serbian part of the Panno¬nian basin, there is a system of peri-Pannonian basins characterized by the appearance of Upper Miocene coal seams in the siliciclastic fill, which provides an ex¬cellent opportunity for testing sequence stratigraphy in young coal basins. In this study, sequence stratigraphy was applied to coals in the Drmno Depression, ...Anastasia Ninić, Dragana Životić, Dejan Radivojević.

Tracking of the temporal dependency of fading of the human footprint temperature contrast
In certain situations, it is extremely important to determine the exact time “someone” entered or crossed the forbidden zone of a military or strategic installation, a red zone of radioactive, chemical, or biological contamination, a bank or similar structure. Standard security measures include ordinary video surveillance using cameras that operate in the visible range of the electromagnetic spectrum, as well commercial thermal imaging cameras [1, 2]. The paper presents the results of experiments that suggest another possible use of ...Stevan Đenadić, Ljubiša Tomić, Vesna Damnjanović, Darko Vasiljević, Danica Pavlović.

The impact of calculation of resources and reserves on mining activity in Serbia
The appearance of interest of the world's most important mining companies i for investment in Serbia imposes the problem of harmonization of domestic legislation with foreign ones. In this paper, specific categorization and classification of mineral raw materials, which do not match in domestic and foreign practice, are treated. The existence of such a conflict of criteria in use for categorization and classification can lead to misunderstanding and create certain complications in business. The following sections outline some of ...geological exploration, deposits, solid mineral raw materials, mineral projects, mineral resources and reservesJelena Zakonović, Katarina Urošević, Radmila Gaćina.

The optimization of auxiliary machinery in open-cast lignite mines: a case study of bulldozers
One of the most important prerequisites for the successful operation of the open-cast lignite mine is to carry out all the auxiliary works timely with the necessary quality. The most important and most commonly used auxiliary machines are bulldozers. Engaging time of bulldozers use is in direct relation with the coefficients of the time and capacity utilization of the continuous system for the excavation of coal and tailings, which indicates their importance. More than 100 bulldozers have been hired ...Dragan Ignjatović, Predrag Jovančić, Stevan Đenadić, Ivan Janković, Ivica Ristović.

Effect of Properties of Working Fluids on the Efficiency of a Low-Temperature Organic Rankine Cycle
Decarbonization of all segments of energy systems, both on the supply and demand side, is one of the main goals of the energy transition. Electricity supply in the future will largely rely on generation from intermittent energy sources: wind and solar. Locally available, non-utilized alternative low-temperature energy sources as hydro-geothermal wells, and abounded oil and gas wells, have the potential to provide continual energy production over the year. Electricity generation from these energy sources is carried out with working ...Marija Živković, Aleksandar Mijatović, Dejan Ivezić, Boban Pavlović.

Analysis Of the Process Of Carbon Capture Utilization And Storage In Underground Reservoirs
John Nyame (2024)The importance of mitigating the effects of global climate change has necessitated an in-depth exploration of innovative strategies to reduce carbon dioxide (CO2) emissions. Among these strategies, Carbon Capture, Utilization, and Storage (CCUS) has emerged as a promising and transformative solution. This master thesis delves into the diverse realm of CCUS processes, aiming to unravel the positives challenges, and opportunities within this dynamic field. The analysis begins with a systematic examination of carbon capture technologies, encompassing post-combustion, pre-combustion, and oxy-fuel combustion ...John Nyame.

Possibility of application of fuzzy logic for stability assessment of underground facilities
Rudnici sa podzemnom eksploatacijom uglja u Republici Srbiji deo su Javnog preduzeća za podzemnu eksploataciju uglja Resavica (JP PEU). U rudnicima kompanije JP PEU podzemne prostorije se trenutno grade tehnologijom bušenja i miniranja. Ova metoda, koja se koristi u srpskim rudnicima uglja, pokazala je svojom brzinom, efikasnošću, troškovima i drugim elementima da više nije prihvatljiva. Klasičan metod izgradnje podzemnih prostorija ne omogućava zadovoljavajuću produktivnost, jer se tehnološke operacije ovog metoda, bušenje i miniranje, izvode ručno i zahtevaju neprihvatljivo mnogo ...Luka Crnogorac, Rade Tokalić, Đurica Nikšić, Saša Jovanović .

Application of the Fuzzy theory in the evaluation of operating parameters of auxiliary mechanization on open-cast coal mine, case study: pipelayers
Achieved operating parameters are the main indicator of the work quality and selection of mining machines. The effectiveness of a coal mine is correlated with the availability of basic and auxiliary machines. The main task of auxiliary machines in lignite mines is to achieve optimal working conditions. From an economic point of view, auxiliary machines generate up to 20% of the lignite mines' total costs. These are the primary reasons for analyzing their current work and making decisions in ...Stevan Djenadić, Miloš Tanasijević, Filip Miletić, Predrag Jovančić.
