Техно-економска оцена подземног откопавања лежишта бакра применом коморно-стубне методе
Александра Бараћ (2024)Коморно-стубна метода са блоковским откопавањем и засипавањем откопа паста засипом омогућује високу продуктивност, флексибилност при раду, остварење пројектованог производног задатка, минимално осиромашење откопане руде, у овом случају руде бакра, висок степен искоришћења расположивих рудних резерви. Припрема лежишта за експлоатацију представља инвестицију у рударској производњи,а сам коначан производ треба ,не само да отплати те трошкове, већ и да донесе новчану добит.Самим тим је од великог значаја адекватан одабир методе откопавања, која ће на најбољи могући начин испунити све захтеве.Основни показатељи ......

A bilingual digital library for academic and entrepreneurial knowledge management
A generic knowledge management process of organization, storage and retrieval of knowledge can suitably be fitted in a digital library. In the digital and knowledge age digital libraries can be used in knowledge management to handle intellectual assets and support knowledge creation. A multilingual digital library either stores content in more than one language or provides multilingual query access to monolingual content.

Terminology Acquisition and Description Using Lexical Resources and Local Grammars
Acquisition of new terminology from specific domains and its adequate description within terminological dictionaries is a complex task, especially for languages that are morphologically complex such as Serbian. In this paper we present an approach to solving this task semi-automatically on basis of lexical resources and local grammars developed for Serbian.

Integrative GHG Assessment in Oil and Gas Industry
Reducing greenhouse gas emissions is one of the main targets of national strategies in European countries. As a main contributor to emissions, the energy sector is recognized as the most promising to apply measures and actions aimed to decrease GHG emissions.

Evaluation of the effects of wastewater heat pump integration into district heating systems by simulation
Dejan Ivezić, Marija Živković, Dimitrije Manić, Aleksandar Madžarević, Boban Pavlović, Dušan Danilović (2023)The integration of wastewater heat pumps (using purified water) in district heating systems is analyzed in this paper. The simulation procedure is proposed to analyze the impacts of stochasticity of purified water temperature and flow to heat pump integration and operation. The analysis includes calculation of the daily and seasonal coefficient of performance, as well as fossil fuel savings and CO2 emission reduction due to wastewater heat pump use. The proposed procedure is implemented for the case study in ...Dejan Ivezić, Marija Živković, Dimitrije Manić, Aleksandar Madžarević, Boban Pavlović, Dušan Danilović.

Influence of DEM resolution on numerical modelling of debris flows in RAMMS - Selanac case study
Debris flows induced by intensive rainfall represent very hazardous phenomena in many parts of the World. Methods for prediction of runout distance of flow like mass movements are different and depending on the input data, rheology, and available or appropriate numerical solution. However, sometimes it is not easy to obtain pre event and post event high-resolution data in the rural or mountainous area. Thus, the topology of terrain is the most important input parameter for the every real case ...... of initial parameters and deposition zones. The Selanac debris flow was triggered after extreme precipitation of about 230 mm over a period of 72 h in May 2014.The Selanac is a complex debris flow, with large depth in source zone (30m), and length of about 1.5km.

The application of ArcGIS for assessing the potential of solar energy in urban area: The case of Vranje
In order to determine the solar energy potential for a specified location, it is crucial to consider the latitude, altitude, slope, terrain morphology, atmospheric conditions, etc. Such a complex calculation and mapping of solar energy can be done using the ArcGIS geoprocessing tool, named Area Solar Radiation (ASR). By using the ASR tool, supported with the adequate input data, it is possible to calculate the maximum solar radiation energy (irradiation) for a defined area and for a specified time ...... value corresponding to its elevation (PBC GIS, 2019). For the generation of the DEM generally data issued from different sources can be used (Taud H. et al., 1999): • Contourlines (from existing maps), • Photogrammetric (aerial photography or digital satellite imagery), • Field data.

Effects of Energy Production and Consumption on Air Pollution in Serbia
Marija Živković (2019)Energy production and combustion, mostly from unregulated or inefficient fuel combustion, are the single most important anthropogenic sources of air pollutant emissions. Energy sector in Serbia is highly fossil fuel intensive: 87.88% of energy consumed in Serbia is related to fossil fuels, while almost 95% of energy sources are combusted. In 2017. energy related carbon dioxide emission in Serbia is was 47.95 million tones. The main source of carbon dioxide emission was coal, responsible for almost 70% of energy ...... s-2018 11.

Eksploatacioni učinci ugljenih sistema na površinskom kopu Tamnava–Zapadno polje
U radu su analizirani eksploatacioni učinci ugljenih sistema na površinskom kopu Tamnava–Zapadno polje. Period analize je prvih šest meseci tekuće godine. Analiza je vršena sa aspekta ostvarene proizvodnje, kvaliteta uglja, efektivnog vremena rada, kapacitetnog i vremenskog iskoršćenja i zastoja sistema. Za poređenje podataka različitih parametara koji po svojoj prirodi nisu međusobno uporedivi, u radu su korišćene metode višekriterijumskog odlučivanja.... period od prvih šest meseci rada u tekućoj godini prikazana su u tabeli 2.3.

Планирање – функција менаџмента пројекта минералне индустрије
Жељко Вучић (2024)Просторно планирање је комплексан мултидисциплинаран процес утврђивања оптималног распореда људи, добара и делатности на одређеној територији ради његове оптималне употребе. Циљ просторног планирања је распоредити и најбоље користити садржаје у простору што је неизводљиво без детаљних анализа потенцијалних, штетних агенаса на целокупно подручје и његово становнисштво. Утицај рударства на окружење вишеструко се повећао након увођења технологије површинске експлоатације минералних сировина, али и свеукупног лошег дејства на животну средину. Под појом животне средине подразумевамо природне и радом створене вредности у ...... paljeBMHCKOr KaMcHa, IHITO je H NOTBpDbeHo Ha Oa3H HcnMTHBaMa KBaJIHTATHBHHMX OCOOHHa CHDpOBHHC H MOTryhHoOcTH MeHe yrmoTpeOec.
