Application of MCDA in the determination of optimal block size for open-pit modelling and mine planning
The process of creating a geological block model as the basis for a further detailed design and planning of mining operations is a very responsible task. Errors made during this initial process are transferred to all other phases of the mining project. Certainly, one of the most important decisions for the modelling process is the choice of the appropriate size of the blocks that form the model itself. The determination of the optimal block size is not a simple ...dimenzije minibloka, višekriterijumska analiza, AHP, modeliranje ležišta, planiranje na površinskim kopovimaPetar Marković, Dejan Stevanović, Milica Pešić Georgiadis, Mirjana Banković.

A first attempt at a provenance study in the Jadar block (Serbia) by means of U-Pb zircon geochronology
У раду су коришћени U-Pb геохронолошки подаци добијени мерењем циркона из магматских стена које пробијају Јадарски блок. Ови подаци коришћени су да бисмо што ближе утврдили порекло циркона, и одатле донели закључке о геолошком развоју овог потенцијално “егзо - тичног” блока. Анализирани су циркони гранитоидних масива Цера и Бо рање као и циркона из епикластита pietra verde на планини Бобија, тријаске старости. У четрнаест узорака гранита и епикластита анализирано је око 600 зрна, од којих је око 30–40% зрна имало наслеђена језгра која су коришћена за ...Georg Löwe, Dejan Prelević, Kamil Ustaszewski.

Application of the Fuzzy theory in the evaluation of operating parameters of auxiliary mechanization on open-cast coal mine, case study: pipelayers
Achieved operating parameters are the main indicator of the work quality and selection of mining machines. The effectiveness of a coal mine is correlated with the availability of basic and auxiliary machines. The main task of auxiliary machines in lignite mines is to achieve optimal working conditions. From an economic point of view, auxiliary machines generate up to 20% of the lignite mines' total costs. These are the primary reasons for analyzing their current work and making decisions in ...Stevan Djenadić, Miloš Tanasijević, Filip Miletić, Predrag Jovančić.

Modeliranje tehnoloških procesa u rudarstvu u uslovima nedovoljnosti podataka primenom teorije grubih skupova
Zoran M. Štirbanović (2015-07-01)Rudarstvo, a u okviru njega i priprema mineralnih sirovina, se odlikuje složenošću tehnoloških procesa što je posledica velikog broja uticajnih parametara. Samim tim je potrebno biti veoma obazriv prilikom donošenja odluka u oblasti rudarstva. U cilju što efikasnijeg funkcionisanja procesa, moguće je primeniti različite metode koje služe za pojednostavljenje procesa odlučivanja. Jedna od takvih metoda jeste i teorija grubih skupova. Ona predstavlja relativno novu matematičku teoriju koja je pogodna za razumevanje nepreciznih i nepotpunih podataka kao i za otkrivanje ...rudarstvo, priprema mineralnih sirovina, teorija grubih skupova, višekriterijumsko odlučivanje, flotacijsko jalovište, flotacijski kolektor, flotaciona mašinaZoran M.

Development of the Availability Concept by Using Fuzzy Theory with AHP Correction, a Case Study: Bulldozers in the Open-Pit Lignite Mine
Stevan Đenadić, Dragan Ignjatović, Miloš Tanasijević, Uglješa Bugarić, Ivan Janković, Tomislav Šubaranović (2019)Availability is one of the most used terms in maintainability engineering. This concept is used to denote: The quality of service of an engineering system, i.e., machines, weak points’ analysis, asset management, as well as making decisions in the process of life cycle management. Availability is an overall indicator and contains partial indicators that are oriented towards reliability, maintenance, and logistical support. Availability presents a variable value and changes in time and space. Usually, availability is shown as the ...Stevan Đenadić, Dragan Ignjatović, Miloš Tanasijević, Uglješa Bugarić, Ivan Janković, Tomislav Šubaranović.
