  • Моделирање утицаја одступања линије најмањех отпора од пројектоване на интензитет потреса од минирања

    Стефан Милановић (2024)
    Према дефиницији линија најмањег отпора представља најкраће растојање од центра минског пуњења до слободне површине. Oвим истраживањем представљен је утицај линије најмањег отпора, као и њеног одступања од пројектоване на интезитет потреса услед минирања. Проблем линије најмањег отпора је веома заступљен у пракси, где се занемарује изглед слободне површине, који може бити врло неправилан. Линију најмањег отпора је потребно мерити целом дужином минске бушотине према слободној површини, иако је у пракси случај да се мери најчешће као растојање од ...

  • Upravljanje resursima podzemnih voda severne Bačke

    Bojan B. Hajdin (2013-03-07)
    Vodosnabdevanje gradova i naselja severne Bačke vrši se u potpunosti iskorišćavanjempodzemnih voda. Najznačajnije količine podzemne vode namenjene za piće zahvatajuse iz izdani u vodonosnim pleistocenskim naslagama koje su poznate kao osnovnivodonosni kompleks, dok su danas u vodosnabdevanju manje zastupljene vode izizdani u pliocenskim sedimentima i prve, slobodne izdani rasprostranjene plitko ispodpovršine terena.Pored snabdevanja stanovništva, veliki potrošači podzemne vode su i industrijskapreduzeća, a zbog loših uslova i nerazvijenih sistema za navodnjavanje sve veći korisnicivoda prve izdani postaju i poljoprivredni proizvođači.Geološka ...

  • Analysis of the exhaust emissions inventory from auxiliary mining machines

    Stevan Đenadić, Aleksandar Mirković, Jovana Mitrović, Filip Miletić, Predrag Jovančić, Dragan Ignjatović (2023)
    Open-pit coal mines are equipped with a large number of mining machines and vehicles with diesel engines. Due to common daily operation of these machines and vehicles large amounts of exhaust gases which contain numerous pollutants are emitted into the atmosphere. The demand to reduce air pollution induced the activities in developed countries to map and calculate all gases emitted by industries to formulate and select adequate preventive activities. In collaboration with machine manufacturers, emission standards for off-road machines ...

  • Hyperpycnites within the Devonian-Carboniferous flysch of the Carpatho-Balkanides (Kostadinovica, eastern Serbia)

    Miloš Radonjić (2020)
    This study presents new discoveries of vascular plants and the trace fossil Dictyodora liebeana (GEINITZ) from the Devonian–Carboniferous Kučaj-Zvonce flysch of the Carpatho-Balkanides and the implications of this fossil association for its sedimentary setting. The occurrence of the described plant debris in a deep-marine environment indicates the presence of hyperpycnites within the siliciclastic turbidites exposed at the Kostadinovica locality. The sedimentological data and the characteristics of the fossil material support the proposed model in which the sediment was at ...

  • Using gravity data to define structural correlation affecting the formation of Neogene basins

    Snežana Ignjatović, Ivana Vasiljević, Branisav Sretković, Milanka Negovanović (2023)
    A gravity survey can help to define the structural correlation in the study area. The structures that have influenced the development of Neogene basins can be defined using gravity data. By applying mathematical transformations to gravity data, the geological structures (faults, nappes, etc.) that impacted the formation of Neogene basins can be defined. We have taken the part of the Dinarides as the test region. The paper presents the results obtained using the procedure residual, vertical gradient, and total ...

  • Analiza uporednog praćenja temperature površine ohlađenih materijala pri njihovom zagrevanju do ambijentalne temperature

    Stevan Đenadić, Ljubiša Tomić, Vesna Damnjanović, Katarina Nestorović (2021)
    U datom eksperimentalnom radu su termografskim metodama ispitivane termofizičke karakteristike različitih materijala. Za ispitivanja su izabrani mesingani niovčić, ugalj i pelet, jer imaju različita termoizolaciona svojstava i različito stanje površine. Uzorci su najpre hlađeni, a zatim je njihovo zagrevanje na sobnoj temperaturi praćeno termalnom kamerom. U drugom delu eksperimenta, korišćena je impulsna termografija, a zagrevanje površine uzoraka vršeno je svetlosnom pobudom.

  • Palaeoflora of Kamenica (Pranjani Basin, western Serbia)

    Zorica Lazarević, Ljubica Milovanović, Jelena Milivojević, Ivana Vasiljević (2019)
    Palaeofloras of the Paleogene in Serbia are relatively rare, especially in comparison with floras from Neogene sediments. Most Paleogene phytoas sociations from the territory of Serbia existed in a dry and warm climate. The youngest Paleogene phytoassociation originates from the Pranjani Basin (Western Serbia), locality Kamenica. The age of this palaeoflora is determined as Late Oligocene. This fossil plant assemblage is different from other Paleo gene phytoassociations.The palaeoflora from Kamenica is characterized with leaf imprints larger than in other ...

  • Modeliranje buke u urbanoj sredini u okolini Doma zdravlja u Pančevu

    Stefan Mandić (2024)
    Prisustvujemo epohi gde buka predstavlja veoma rasprostranjen i moderan fenomen koji možemo deklarisati kao problem. Svedoci smo toga da moderni problemi zahtevaju malo drugačiji pristup nego u prošlosti, odnosno zahtevaju moderna rešenja. Samim tim, vremenom je došlo do modernizacije alata,u ovom slučaju došlo je do razvoja modela za rasprostiranje buke koji su se vremenom unapređivali pa tako danas imamo jedno moćno sredstvo za borbu protiv buke u vidu kompjuterskog softvera.Ovaј master rad, pod nazivom „Modeliranje buke u urbanoj sredini ...

    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. It ...

  • Determining the Availability of Continuous Systems at Open Pits Applying Fuzzy Logic

    Miljan Gomilanović, Miloš Tanasijević, Saša Stepanović (2022)
    This work presents a model for determining the availability of continuous systems at open pits by applying fuzzy logic and fuzzy inference systems. The applied model was formed by the synthesis of independent partial indicators of availability. The model is based on an expert system for assessing the availability of continuous mining systems. The availability of the system, as a complex state parameter, is decomposed into the partial indicators, reliability, and convenience of maintenance, and the fuzzy compositions, used ...
