Mineragenetske karakteristike i potencijalnostjuvelirskih mineralnih resursa leckog vulkanskog kompleksa
Zoran Ž. Miladinović (2012-12-11)Jedan od najznačajnijih regiona u Srbiji, sa stanovišta potencijalnosti juvelirskih mneralnih resursa, predstavlja lecki vulkanski kompleks, tercijarne starosti i dominantno andezitskog sastava. Ovaj vulkanski kompleks površine preko 700km2 nalazi se u južnojSrbiji na prostoru imeđu Kuršumlije, Lebana i Medveđe.Prvi su pažnju na juvelirske mineralne sirovine ovog prostora obratili graditeljiJustinijane Prima-e (VI vek). Najintenzivnija istraživanja izvršena su u periodu 1980–1982. ali samo na malom prostoru krajnjeg jugoistočnog dela vulkanskog kompleksa.U Leckom vulkanskom kompleksu dominiraju andezitske stene i njihovi piroklastiti.Smatra se ...vulkanski kompleks, mineragenetske karakteristike, juvelirski mineralni resursi, nalazišta, potencijalnost, kvarc, ametist, ahat, kalcedon, jaspis, prognoza... sirovina, a posebno izučavanja fizičko-tehničkih svojstava ametista izvršio, je Stanković S.,. Za razliku od drugih autora koji su istraživanja uglavnom vršili u neposrednoj okolini polimetaličnog ležišta Lece, Stanković je istraživanja proširio na širi rejon istoimenog rudnika Godine 1965, nemački ...

Cutting elements of bucket wheel excavators in lignite opensast mines: Methodology and performed solutions
Dragan Novaković, Predrag Jovančić (2016)Bucket and cutting elements geometry (teeth and hardened steel) have very powerful impact on effective operation of bucket wheel excavator, and that`s why, problems of optimal geometry of elements in specific conditions always are of special interest in mining science and technique. If we want to achieve satisfactory utilization of bucket wheel excavator, it is necessary to modulate geometry material characteristics and technological parameters, as regards bucket wheel excavator work regime, and bucket wheel working performances, and also bucket ...Dragan Novaković, Predrag Jovančić.

Верификација етажних транспортера на угљеном систему – површински коп Дрмно
Тамара Андрејевић (2024)У савременом рударству, површински копови угља наилазе на различите проблеме које треба превазићи зарад добијања потребне количине угља. Као највећи потрошачи овог енергента јављају се термоелектране, где на основу овога можемо да закључимо колико су блиско повезани добра и континуирана производња на површинском копу и рад термоелектрана. Са циљем да се обезбеди стабилна и континуирана производња, потребно је да се направи добар одабир транспортера. У овом раду, за потребе верификације затезне чврстоће траке и снаге погона транспортера, коришћен је ......

Underground loading-haulage equipment selection with application of topsis method with different weighting methods of criteria
The choice of adequate mining machines is one of the most complex problems in the underground exploitation of mineral raw materials. The weight of such a decision is reflected in the high prices of these machines and the occurrence of even greater costs during their use if their choice was wrongly conceived. There are numerous examples from practice in which such decisions were made solely on the basis of comparing the prices of machines, without considering any of the ...utovarno-transportna mehanizacija, izbor, TOPSIS, entropija, standardna devijacija, težina kriterijumaVladimir Krivošić, Luka Crnogorac, Rade Tokalić.

Business Models for Small-scale Biomass Projects Development
Biomass is recognized as the most promising renewable energy source in Serbia. The share of biomass in Serbian final energy consumption is over 10%, but mostly related to traditional use in stoves and ovens. One of the main obstacles for wider implementation of contemporary biomass facilities is the inexperience of consumers and stakeholders in the implementation of “innovative” business models, especially in the cases of small-scale projects. In this paper, three different business models (public utility company, energy cooperative ......

Tektono-termalna evolucija kontakta Dinarida i Karpato-Balkanida u području Jastrepca
Dalibor Erak (2019)Predmet istraživanja doktorske disertacije je tektonska evolucija područja planine Jastrebac u centralnoj Srbiji, gde višefazna tektonska aktivnost od mezozoika do danas komplikuje rekonstrukciju strukturnih odnosa i geološke evolucije ovog prostora. Kompleksna višefazna evolucija planine Jastrebac u Srbiji je demonstrirana kombinovanjem kinematskih podataka prikupljenih na terenu i mikrostrukturnih opservacija sa dodatnim termohronološkim podacima “fission track” i podacima odredbe starosti metodom U-Pb na cirkonima.

Метода променљивих околина за решавање проблема p-центра са поузданом мрежом
У овом раду је разматран проблем p-центра са поузданом мрежом (енгл. Reliable p-center facility location problem - RpCFLP). Решавање проблема подразумева иницијално успостављање p ресурса и алокације корисника, као и накнадну реалокацију корисника у складу са новонасталим сценаријима који садрже информације о онеспособљеним ресурсима и осталим измењеним улазним подацима. За решавање посматраног проблема предложена је метахеуристика заснована на итеративној варијанти основне методе променљивих околина (енгл. Iterated basic variable neighborhood search - IBVNS).

Correlation Between Dynamic CBR and Compaction and Bearing Capacity of Pavement Foundation Layers
This paper presents a dynamic California Bearing Ratio (CBRd) device that can be used on a prepared pavement foundation layer to obtain a certain parameter of the tested material in the laboratory and in situ in a direct and fast way. For the selected natural material (gravel), it is shown that the laboratory CBRd can be used to estimate the compaction and bearing capacity, because it correlates well with the parameters of the standard and modifed Proctor compaction tests. ...korelacija parametara, donji slojevi saobraćajnica, laboratorijska i terenska ispitivanja, dinamički kalifornijski indeks nosivosti CBRd... empirical formula [8], as follows: CBR, = 24.26 p/ s'”., () With a force of 7070 N and a piston diameter of 50 mm (cross-section of 1963 mm?), Eq.
