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. This paper presents the research related to the analysis of auxiliary machine parameters with the case study for a hydraulic excavator. The purpose of the analysis was to develop a model of rating quality of service of the ...Stevan Đenadić, Miloš Tanasijević, Vladimir Milisavljević, Dragan Ignjatović, Predrag Jovančić.

Tektonske i litostratigrafske karakteristike šireg područja Grivske (Zapadna Srbija)
Nikola Otašević (2024)U ovom radu predstavljene su osnovne geološke karakteristike šireg područja Grivske. U litostratigrafskom pogledu na ovom prostoru prisutne su paleozojske, mezozojske i kenozojske sedimentne, magmatske i metamorfne stene. Tvorevine karbona su predstavljene semimeta-morfisanim tvorevinama.Tvorevine trijaske starosti su predstavljene slojevitim i masivnim krečnjacima, dok su tvorevine jure predstavljeni produktima ofiolitskog melanža. Takođe, prisutne su i tvorevine senona koje su predstavljene masivnim krečnjacima. U neogenoj sukcesiji dominiraju klastiti miocena, dok su u kvartaru zastupljeni različiti tipovi fluvijalnih, deluvijalnih i deluvijalno-proluvijalnih tvorevina. ...Nikola Otašević.

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. Neophodno je isprojektovati magacin tako da ispuni sve zahteve po pitanju količine i načina skladištenja eksploziva, ...... eksploziva i detonatora) __ __ [] || B ii oO Š O [} o => - {[=" i= 5 |. e -| 'B O 6 6 = o | — [ » | o o = = S -i r g q '= = o ” v |=" [= o Fs o Me N s a >cg Š 5I BE EJMG S šB Sl|S|šmsm| 9 < o i » 7ij:: B= = , , . | .S.S 8 o - Ws!ı PlBB B E g g ı a|BS|E BI B o | e . -= ” o o o = o | |l i o od O ...

Anticipated sulfur dioxide emissions from coal-fired power plants
Aleksandar Madžarevic, Predrag Jovančić, Stevan Đenadić, Filip Miletić, Miodrag Ristović, Miroslav Crnogorac (2024)Southeastern Europe (SEE), which includes Serbia, along with Germany and Poland, is one of the largest producers of solid fuels in Europe. Despite growing environmental concerns, coal, especially lignite, persists and remains the dominant fuel for electricity generation in this region. Concurrently, these power plants emerge as the predominant emitters of pollutants in all the observed states. To conduct a comprehensive analysis, data on major emitters within the European Union were gathered, allowing for a detailed comparison with SEE ...Aleksandar Madžarevic, Predrag Jovančić, Stevan Đenadić, Filip Miletić, Miodrag Ristović, Miroslav Crnogorac.

Анализа квантитативног и квалитативног режима подземних вода: Случај изворишта за водоснабдевање Друговца у Смедереву
Милан Павличић (2024)У раду су приказани резултати истражних радова који су спроведени у периоду од 13.04.2018. до 31.05.2019, у циљу дефинисање режима и категоризације резерви подземних вода на изворишту за водоснабдевање Друговца у Смедереву. Бунарима ИЕБДР-1/93 и ИЕБД-1/2002 су каптирани песковити седименати неогене старости. У току режимских осматрања вршени су тестови црпења, осматрања нивоа подземних вода, режимa падавина као и квалитетa подземних вода. Утврђене су укупне резерве подземних вода у количини од 5,3 l/s.
