  • Razvoj integralnog modela za optimizaciju diskontinualnog sistema proizvodnje na površinskim kopovima nemetala

    Miodrag Čelebić (2024)
    Izbor optimalne mehanizacije u diskontinualnom sistemu transporta je jedna od najvažnijih odluka koju treba donijeti prilikom projektovanja površinskih kopova. Pri izboru optimalne mehanizacije, uticaj ima veliki broj faktora, kako prirodnih – geoloških i ekoloških, tako i tehničkih, ekonomskih i socijanih. Neki od njih se mogu izraziti numerički, u određenim mijernim jedinicama, a neki opisno, lingvističkim varijablama, shodno uslovima koji vladaju na rudnim ležištima, a koje karakterišu visok stepen neizvjesnosti i neodređenosti kako prilikom istraživanja, tako i tokom procesa eksploatacije ...

  • Bezbednosna rastojanja u jamskim magacinima eksploziva u domaćoj i međunarodnoj praksi

    Luka Crnogorac, Ognjen Popović, Toma Jovičić, Veljko Lapčević (2024)
    Projektovanje jamskih magacina eksploziva predstavlja složen inženjerski problem. Sama namena jamskih magacina zahteva ispunjenost niza uslova koji se odnose na bezbedno pozicioniranje magacina, ispunjenost uslova ventilacije, pristupa, rukovođenja magacinom, načina skladištenja eksplozivnih sredstava, protivpožarne zaštite, elektro zaštite itd. Veoma važan parametar prilikom projektovanja jamskih magacina eksplozivnih sredstava predstavlja minimalno sigurnosno rastojanje između susednih komora u kojima su smeštena eksplozivna sredstva u cilju sprečavanja potencijalnog neželjenog dejstva vazdušnog udarnog talasa, razornog dejstva eksplozije i seizmičkog dejstva eksplozije. U ovom radu su prikazani ...

  • 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 ...

  • From DELA Based Dictionary to Leximirka Lexical Database

    Biljana Lazić, Mihailo Škorić (2020)
    In this paper, we will present an approach in transforming Serbian language Morphological dictionaries from a DELA text format to a lexical database dubbed Leximirka. Considering the benefits of storing data within a database when compared to storing them in textual documents, we will outline some of the functionality that the database has made possible. We will also show how hand-made rules that use category labels lexical entries are marked with can be used to link lexical entries. ...

  • Debris-flow Susceptibility Assessment in Flow-R: Ribnica River Case Study

    Ksenija Micić, Miloš Marjanović, Biljana Abolmasov (2024)
    Debris flows are among the most dangerous erosional geohazards due to the fast rate of movement and long runout zones. Even though the initiation can be triggered in mountainous areas, inhabited and with steep slopes, their propagation and deposition can endanger not only buildings and infrastructure in the urbanized areas, but also threaten human lives. As these initiation areas usually represent unattainable terrains with rapid vegetation cover development, field observations and aerial photo analysis become high-demanding tasks. Consequently, medium-to-regional ...

  • A hundred years of Milutin Milanković's climate change theory - geological implications

    Dejan Radivojević (2020)
    Миланковићева теорија циклуса објављена пре сто година је најважнија теорија у наукама које проучавају климу и имала је велики утицај на дисциплине које се баве Земљом. Ипак, његов рад је чекао више од педесет година да би добио потврду. Може се рећи да Миланковићев рад највећи утицај на геологију има у изради астрономске временске скале, подршци хипотези континенталног дрифта и палеоклиматологији. Добри резултати примене астрономске временске скале на неогене седименте иницирали су примену ове методе у мезозојским и у последње ...

  • Possibilities of retro-digitalized German-Serbian Mining Dictionary

    Biljana Lazić, Olivera Kitanović, Ivan Obradović (2019)
    U radu će biti prikazan opis procesa retrodigitalizacije dvojezičnog Nemačko-srpskog rudarskog rečnika iz 1923. godine čiji je autor rudarski inženjer Dragutin Stepanović (Степановић, 1923). Ovaj rečnik je zasnovan na skoro 4 000 leksičkih zapisa koji su prevodilački ekvivalenti ili uputnice. Umesto predgovora autor daje uvid u svoje pismo upućeno “Ministru šuma i rudnika” u kome piše o nameri da zabeleži reči koje se koriste u narodu kako bi izbegao upotrebu nemačkih reči. Iako broj odrednica nije toliko veliki, rečnik ...

  • Influence of DEM resolution on numerical modelling of debris flows in RAMMS - Selanac case study

    Jelka Krušić, Biljana Abolmasov, Mileva Samardžić Petrović (2019)
    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 ...

    Nikola Lilić, Ranka Stanković, Ivan Obradović (1997)
    roblems relating to mine ventilation systems analysis are usually of a very complex nature. They involve the estimation of numerous interdependent parameters pertaining to the network status, ventilation status, ventilation system stability, air current losses, climate conditions, gas state, fire risk and dangerous dust pollution risk. The solution to these problems relies, to a great extent, on numerical methods. With the development of computer technology these methods were incorporated as numerical routes in software packages, such as the mine ...
