  • Long-term planning methodology for improving wood biomass utilization

    Vladimir Vukašinović, Dušan Gordić, Marija Živković, Davor Koncalović, Dubravka Živković (2019)
    The insufficiently developed forest management system is often followed by undeveloped forest resources supply chain and insufficient institutional support. These cause inefficient usage of fuel-wood as well as huge amounts of unused forest residues. In order to achieve optimal and long-term sustainable utilisation of biomass, an original methodology based on the interaction of mathematical optimization and backcasting approach has been developed. Mathematical optimization is used for both generation and consideration of techno-economic parameters of the forest biomass supply chain. ...

  • Fuzzy Model for Risk Assessment of Machinery Failures

    Dejan V. Petrović, Miloš Tanasijević, Saša Stojadinović, Jelena Ivaz, Pavle Stojković (2020)
    The main goal of this research was the development of an algorithm for the implementation of negative risk parameters in a synthesis model for a risk level assessment for a specific machine used in the mining industry. Fuzzy sets and fuzzy logic theory, in combination with statistical methods, were applied to analyze the time picture state of the observed machine. Fuzzy logic is presented through fuzzy proposition and a fuzzy composition module. Using these tools, the symmetric position of the ...

  • Vodosnabdevanje i održivo upravljanje podzemnim vodnim resursima u Srbiji

    Dušan Polomčić, Zoran Stevanović, Dragoljub Bajić, Bojan Hajdin, Vesna Ristić-Vakanjac, Petar Dokmanović, Saša Milanović (2012)
    Slično većini evropskih zemalja, udeo podzemnih voda u javnom vodosnabdevanju u Srbiji je oko 75%. Najveće rezerve su akumulirane u vodonosnim naslagama intergranularne poroznosti neogene i kvartarne starosti, kao i u karstnim izdanima. One su jedini izvor vodosnabdevanja pijacom vodom za Vojvodinu i veći deo Srbije. Delovi sa malim rezervama podzemnih voda su Šumadija i južni delovi zemlje, gde se koriste u većoj meri površinske vode. Do sada izvedena hidrogeološka istraživanja pokazuju da se zahvata oko 30% obnovljivih rezervi ...

  • 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 ...

  • Legal framework for recultivation of degraded areas caused by mining exploitation

    Radmila Gaćina (2023)
    Prilikom površinske i podzemne eksploatacije uglja eksploatacioni sistemi oštećuju veće ili manje površine zemljišta. Iskustva pokazuju da su oštećenja zemljišta znatno veća kod površinske eksploatacije, gde je prostora degradiran ne samo u konturi rudnika i okoline, već se promene takođe dešavaju u prirodnom okruženju. U članku su predstavljeni rezultati studije zakonskih okvira rekultivacije u nekim zemljama sveta i u Srbiji. Praktično iskustvo rekultivacije pokazalo je da iskorišćenje i devastacija tokom rudarske aktivnosti predstavljaju opasnost ne samo za pogođena ...

  • Preliminary impact assessment of No2 emission from a heating plant on air pollution: case of Zemun, Serbia

    Boban Pavlović, Uroš Pantelić, Marija Živković, Dejan Ivezić (2023)
    The aim of this paper is to provide a preliminary evaluation of the impact caused by NO2 emissions from a heating plant on the local air quality. To model the spatial distribution of NO2 emissions from the heating plant, the AERMOD model was employed. The evaluation was conducted by analyzing and contrasting the simulated NO2 concentration from the heating plant with the overall NO2 concentration recorded at the nearest monitoring station over the entire heating season. The study focused ...

  • Digitalizacija u rudarstvu: Kreiranje sistema za efikasno poslovno izveštavanje

    Stevan Đenadić, Aleksandar Mirković, Veljko Rupar (2024)
    Proces donošenja odluka u oblasti rudarstva i geologije uslovljen je blagovremenim posedovanjem kvalitetnih podataka i informacija. Kompleksnost rudarskih procesa nalaže prikupljanje podataka na dnevnom odnosno na smenskom nivou. Podaci kao takvi bez analitičkog pristupa nisu dovoljni. Kako bi pristup podacima bio brz i efikasan neophodno je posedovanje adekvatnog digitalnog rešenja uz adekvatne centralizovane baze podataka. U ovom radu je dat pregled trenutne pozicije rudarstva sa aspekta digitalne transformacije kao i predlog jednostavnog prototipa u obliku digitalnog sistema za poslovno ...

  • Regional rockfall exposure assessment, experience from Serbia

    Miloš Marjanović, Biljana Abolmasov, Uroš Đurić, Jelka Krušić, Snežana Bogdanović (2022)
    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 ...

  • Ostvarivanje dobiti pri uvođenju sistema agregatnih zamena na osnovnoj rudarskoj mehanizaciji površinskih kopova EPS

    Predrag Jovančić, Ignjatović Dragan, Đenadić Stevan (2021)
    Jedan od osnovnih zadataka na površinskim kopovima uglja je ostvarivanje zadovoljavajućeg vremenskog i kapacitetnog iskorišćenja kontinualnih sistema. Da bi se to postiglo, neophodno je izvršiti izmene u postojećoj strategiji održavanja. Preduslov je uvođenje agregatne zamene vitalnih delova na rudarskim mašinama. Benefiti su višestruki. Očekivani rezultati ovakvog pristupa su: smanjenje zastoja i povećanje vremena rada; direktne materijalne uštede; bolja organizacija rada; racionalizaciju radioničkih i magacinskih kapaciteta; povećanje vrednosti mašina. Da bi se uvela agregatna zamena neophodne su investicije za nabavku ...
