Modeliranje sistema upravljanja zaštitom životne sredine u rudarsko-energetskim kompleksima
Jelena R. Malenović - Nikolić (2016-07-12)Efikasnost funkcionisanja sistema upravljanja zaštitom životne sredine u rudarskoenergetskimkompleksima zavisi od stepena sprovođenja usvojene politike zaštiteživotne sredine i primene preventivnih mera zaštite životne sredine. Nedostatakfinansijskih sredstava za unapređivanje tehnologije eksploatacije, transporta, pripreme iprerade energetskih mineralnih sirovina u našim rudarsko-energetskim kompleksima,negativno utiče na ostvarivanje ciljeva zaštite životne sredine, a posledice radnihaktivnosti rudarsko-energetskih kompleksa dovode do smanjenja nivoa kvalitetavazduha, vode i zemljišta...rudarsko-energetski kompleks, životna sredina, sistem upravljanja,višekriterijumsko odlučivanje, modeliranje...

Tehnologija izrade i opremanje magacina eksploziva za potrebe ležišta bakra
Aleksandar Milojević (2024)Nakon radova otvaranja i početka eksploatacije, rudno telo bakra velikih rezervi zahteva i veliku količinu eksploziva da bi se ostvario zacrtan kapacitet. Samim tim, neophodno je izraditi funkcionalan magacin eksploziva koji će biti pristupačan svim horizontima i koji će moći da ispuni celokupni kapacitet svih horizonata. Obzirom da će se u magacinu skladištiti eksploziv, on mora ispunjavati specijalne uslove kako bi skladištenje bilo bezbedno.

Composition of organic matter and thermal maturity of Mesozoic and Cenozoic sedimentary rocks in East Herzegovina (External Dinarides, Bosnia and Herzegovina)
This paper presents the first data on the organic matter and thermal maturity of Mesozoic and Cenozoic sedimentary rocks in the East Herzegovina region of the External Dinarides. Representative, organic-rich samples from outcropping sedimentary rocks of different ages in the area (Triassic to Neogene) were selected and analysed. The organic matter was studied by Rock-Eval pyrolysis and under the microscope in reflected non-polarized light and incident blue light. The results obtained show the presence of different types of organic ...... Staplin, F. L., Dow, W. G., Milner, C. W. D., O'Connor, D.I., Pocock, S. A. J., van Gijzel, P., Welte, D. H. & Yukler M. A.

Back-arc underplating provided crustal accretion affecting topography and sedimentation in the Adria microplate
Paolo Mancinelli, Vittorio Scisciani, Cristina Pauselli, Gérard M. Stampfli, Fabio Speranza, Ivana Vasiljević (2021)Supported by evidence of deep crustal sources for the observed magnetic anomalies in Central Italy and by outcropping gabbros in the Croatian archipelago, we model the observed gravity and magnetic anomalies in the Central Adriatic Sea and surroundings. We suggest that the major magnetic anomalies in the area are related to a wide underplating and propose that this volume represents the first stage of the back-arc Adria continental breakup in Early Permian times. During the Palaeotethys-Adria collision, underplating has ...Paolo Mancinelli, Vittorio Scisciani, Cristina Pauselli, Gérard M. Stampfli, Fabio Speranza, Ivana Vasiljević.

Effectiveness Analysis of Different Bucket-wheel Excavators
Coal production in open-pit lignite mines in the Republic of Serbia is performed with continuous work systems. In addition to coal production, the same systems are used for the exploitation of large quantities of overburden. According to the reliability concept, continuous systems are in linear connection. If the failure occurs in one part of the system, that will produce a downtime of the entire system. The initial and most important factor of continuous systems is the bucket-wheel excavator.

The series of Fe3−xYxO4 (x=0.00, 0.042 and 0.084, labeled as Y00, Y05 and Y10, respectively) was synthesized using co-precipitation followed by microwave-hydrothermal treatment (MW) at 200°C.

Tехничко решење заштите површинског копа Дрмно од површинских вода у 2025. години
Иван Јованчевић (2024)Објекти одводњавања површинског копа морају поуздано обављати своју функцију, а да су при томе економични. Једна од функцијуа им је и да спрече доток површинских вода у радну контуру површинског копа, као и да воде које доспеју у радну контуру, прихвате и спроведу до водосабирника, а затим је одатле одстране ван радне контуре површинског копа.

Oдређивање броја камиона за транспорт руде на површинском копу Шупља стијена
Грујичић Стефан (2024)Транспорт на површинским коповима се одвија паралелнпо са осталим процесима екаплоатације. Како не би долазило до непредвиђениих трошкова, потребно је усагласити све системе производње. Димензионисање адекватног транспортног система обезбеђује максималну продуктивност механизације и профитабилну експлоатацију. Чињеница да трошкови транспорта заузимају знатан део укупних трошкова иде у прилог томе да је одређивање потребног броја камиона за превоз откопаног материјала од великог значаја.

Aleksandar Sredojević (2024)U momentu kada pritisak na dnu bušotine nije dovoljan da savlada ukupne gubitke pritisaka od dna bušotine do separatora, proizvodnja pomoću ležišne energije nije više moguća i bušotina prestaje sa eruptivnim radom. Kako bi ponovo omogućili proizvodnju fluida iz bušotine, potrebno je primeniti neke od mehaničkih metoda eksploatacije. Najprimenljivije mehaničke metode eksploatacije su: gas lift (GL), dubinske pumpe sa klipnim šipkama (SRP), električne uronjene centrifugalne pumpe (ESP), zavojne pumpe (PCP) i hidraulične pumpe (HP). Jadna od tih metoda koja ...električna centrifugalna pumpa (ESP), proizvodnja fluida, mehaničke metode eksploatacije, Prosper, Pipesim...

BaTiO3/NixZn1−xFe2O4 (x = 0, 0.5, 1) Composites Synthesized by Thermal Decomposition: Magnetic, Dielectric and Ferroelectric Properties
Marija Šuljagić, Ivan Petronijević, Miljana M. Mirković, Aleksandar Kremenović, Adis Džunuzović, Vladimir B. Pavlović, Aleksandra Kalezić-Glišović, Ljubica Andjelković (2023)To investigate the influence of spinel structure and sintering temperature on the functional properties of BaTiO3/NixZn1−xFe2O4 (x = 0, 0.5, 1), NiFe2O4, ZnFe2O4, and Ni0.5Zn0.5Fe2O4 were in situ prepared by thermal decomposition onto BaTiO3 surface from acetylacetonate precursors. As-prepared powders were additionally sintered at 1150 °C and 1300 °C. X-ray powder diffraction (XRPD) and scanning electron microscopy (SEM) coupled with electron dispersive spectroscopy (EDS) were used for the detailed examination of phase composition and morphology.
