  • Nelinearno dinamičko modelovanje potresa izazvanih promenom naponskog stanja pri izradi horizontalnih podzemnih prostorija

    Srđan D. Kostić (2013-11-04)
    U ovoj disertaciji, cilj istraživanja bio je određivanje dinamičkih svojstava potresaizazvanih promenom naponskog stanja pri izradi horizontalnih podzemnih prostorija.Analiza potresa izvedena je sa dva aspekta – u prvom delu istraživanja izučavane suvremenske serije oscilovanja tla za vreme potresa, a u drugom delu vršena je analizastabilnosti fenomenološkog Baridž-Knopof modela bloka sa oprugom. Vremenske serijeoscilovanja tla proučavane su primenom postupka analize surogat podataka, kao ikorišćenjem metoda analize nelinearnih vremenskih serija (primena teoreme orazvijanju skalarne vremenske serije). Analiza vremenskih serija izvedena je ...

  • Development of a petrographic classification system for organic particles affected by self-heating in coal waste. (An ICCP Classification System, Self-heating Working Group – Commission III)

    M. Misz-Kennan, J. Kus, D. Flores, C. Avila, Z. Büçkün, N. Choudhury, K. Christanis, J.P. Joubert, S. Kalaitzidis, A.I. Karayigit, M. Malecha, M. Marques, P. Martizzi, J.M.K. O'Keefe, W. Pickel, G. Predeanu, S. Pusz, J. Ribeiro, S. Rodrigues, A.K. Singh, I. Suárez-Ruiz, I. Sýkorová, N.J. Wagner, D. Životić (2020)
    Self-heating of coal waste is a major problem in the leading coal-producing and consuming countries, independent of the recent or past coal exploitation history. The phenomenon of self-heating is dependent on many factors such as the properties of organic matter (maceral composition and rank), moisture and pyrite content, climate effects, and storage conditions (shape of the dump or compaction of the coal waste). Once deposited, coal waste undergoes oxidation, which can lead to self- heating with the overall temperatures ...

  • Sistem poslovne inteligencije za upravljanje zaštitom na radu u rudarskoj industriji

    Ljiljana R. Kolonja (2016-09-23)
    Postojeća organizacija zaštite na radu na površinskim kopovima uglja često nije umogućnosti da blagovremeno i tačno ukaže na nedostatke, koji mogu u bližoj ilidaljoj budućnosti da budu uzrok narušavanja bezbednosti radnika, ali i uzrokoštećenja materijalnih dobara rudnika. Nemogućnost donošenja pravovremenihodluka je moguće izbeći uvođenjem softverski podržanih sistema za praćenje ianalizu bezbednosti i zaštite na radu.Osnovni cilj ove doktorske disertacije je definisanje metodologije i razvoj modelasistema upravljanja zaštitom na radu, koji će omogućiti savremen, adekvatan isveobuhvatan način praćenja i analize ...

  • Properties of fly ash and slag from the power plants

    Miloš Šešlija, Aleksandra Rosić, Nebojša Radović, Milinko Vasić, Mitar Đogo, Milovan Jotić (2016)
    This paper describes the physical, chemical and mineral properties of ash and slag, which were taken from thermal power plants Nikola Tesla A, Nikola Tesla B, Kostolac A and Kostolac B. The knowledge of the mineralogical material composition is important because the type of minerals directly determines the properties of the fly ash and slag and their possible application. Laboratory tests showed that ash and slag samples consist of the following minerals: amorphous materials, quartz, feldspar, mullite, melilite, cristobalite, ...

  • The optimization of auxiliary machinery in open-cast lignite mines: a case study of bulldozers

    Dragan Ignjatović, Predrag Jovančić, Stevan Đenadić, Ivan Janković, Ivica Ristović (2019)
    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 ...

  • Primena ubrzane konsolidacije kod izgradnje nasipa na deonici priključka Novi Beograd – Surčin autoputa ,,Miloš Veliki"

    Aleksa Tomičić (2024)
    Problem koji se javlja prilikom izgradnje objekata na ne konsolidovanom stišljivom tlu jeste pre svega vezan za prevelika sleganja tla usled opterećenja od objekata, najčešće su to objekti putne infrastrukture (nasipi), ili stambeno poslovni objekti. U tu svrhu se,primenjuju različiti vidovi ubrzanja konsolidacije tla. Stoga za potrebe izrade završnog rada Master akademskih studija studijskog programa geotehnika, na Rudarsko-geološkom fakultetu, izvršena je analiza dva najčešće korišćena postupka ubrzanja konsolidacije: predopterećenjem i ugradnjom peščanih drenova. Glavni cilj ovih postupaka je ...
