  • Tехничко решење заштите површинског копа Дрмно од површинских вода у 2025. години

    Иван Јованчевић (2024)
    Објекти одводњавања површинског копа морају поуздано обављати своју функцију, а да су при томе економични. Једна од функцијуа им је и да спрече доток површинских вода у радну контуру површинског копа, као и да воде које доспеју у радну контуру, прихвате и спроведу до водосабирника, а затим је одатле одстране ван радне контуре површинског копа. Овим завршним радом је сагледано постојеће стање система одводњавања површинских вода на површинском копу лигнита Дрмно у 2024. години, и дато по мом мишљењу једно ...

  • Palinomorfe sa lokaliteta Gostuška reka (Stara planina)

    Ivan Rutović (2024)
    U radu su prikazani rezultati palinološkog istraživanja permsko-trijaskih sedimenata sa lokaliteta Gostuška reka. Palinološki kompleksi su detaljno analizirani, što je omogućilo morfološku, taksonomsku i paleoekološku identifikaciju palinomorfi. Istraživanje je pokazalo prisustvo velikog broja spora i polena golosemenica, dok je polen skrivenosemenica zastupljen u manjem procentu. Na osnovu paleoekoloških analiza, zaključeno je da je tokom formiranja sedimenata na lokalitetu vladala aridna klima, sa povremenim vlažnim fazama koje su omogućavale razvoj močvarne vegetacije.

  • Анализа могућности примене метода повећања степена искоришћења на нафтном лежишту "Ј"

    Иван Савић (2024)
    Комплексно лежиште „Ј“ је сачињено од колектор стена различите стратиграфске припадности и хетерогеног литолошког састава. Лежиште се налази у последњој фази разраде, а током животног века експлоатисано је само примарним методама. У раду је приказана анализа стања разраде лежишта, а као основни фактори који су допринели ниском степену искоришћења лежишта издвојени су вискозност нафте, хетерогеност колектора и пад лежишног притиска. Изведена је хидродинамичка симулациона студија помоћу које је издвојена најпогоднија зона за пилотну примену терцијарних метода. Коришћењем „скрининг“ критеријума ...

  • Coupling of artificial intelligence methods in the development of hybrid intelligent systems

    Ranka Stanković, Ivan Obradović, Nikola Lilić (2001)
    In this paper we present an approach which couples various artificial intelligence (AI) methods in the solution of complex problems that cannot adequately be solved by a single AI method. We argue that the resulting, hybrid intelligent systems (HIS) can be successfully implemented with the use of available AI software libraries. Different coupling methods are analyzed and a classification of hybrid systems based on the chosen method is given. Two case studies of hybrid systems used in mining engineering ...

    The most common problem in contemporary mining practice related to the planning and analysis of ventilation systems is the optimization of partially regulated air distribution in mine ventilation networks. This paper presents a two step optimization procedure for partly regulated air distribution in mine ventilation networks. The first step is the determination of air distribution in all branches using the well known Hardy-Cross method. In the second step the distribution and parameters of air flow regulators with minimum engaged ...
