Asset management and condition monitoring on maintenance of mining equipment lignite mines
Predrag Jovančić (2016)Maintenance strategy, once set, is not permanent. This strategy should be adapted and altered according to the findings, achieved results, variation of mine product prices, changes in the region etc. On the other hand, maintenance strategy should be: safe operation, higher productivity, reduced costs and functionality of complete system. Asset management represents activities through which mine achieves the optimal and sustainable management of its property, in order to meet the plan - realization of production with optimized costs. Therefore, ...Predrag Jovančić.

The impact of calculation of resources and reserves on mining activity in Serbia
The appearance of interest of the world's most important mining companies i for investment in Serbia imposes the problem of harmonization of domestic legislation with foreign ones. In this paper, specific categorization and classification of mineral raw materials, which do not match in domestic and foreign practice, are treated. The existence of such a conflict of criteria in use for categorization and classification can lead to misunderstanding and create certain complications in business. The following sections outline some of ...geological exploration, deposits, solid mineral raw materials, mineral projects, mineral resources and reservesJelena Zakonović, Katarina Urošević, Radmila Gaćina.

Improving efficiency of thermal power plants through mine coal quality planning and control
Главни циљ контроле квалитета угља у рудницима лигнита је снабдевање термоелектрана угљем чији квалитет мора да се креће унутар одређених квалитативних ограничења. Карактеристике угља могу да утичу на ефикасност, поузданост и расположивост како котла тако и јединица за контролу емисије. У овом раду аутори су презентовали интегрисану симулацију рударског процеса као нови приступ у истраживању променљивости калоричне вредности угља приликом експлоатације комплексног лежишта лигнита. Резултати таквог приступа омогућавају драгоцен увид у перформансе континуалног рударског система у смислу контроле променљивости ...Mirjana Banković, Dejan Stevanović, Milica Pešić, Aleksandra Tomašević, Ljiljana Kolonja.

Self-Engineering: Possibilities for Maintenance Operations in the Mining Machines Industry
Self-engineering is a relatively new branch of knowledge that aims to understand how systems could “autonomously” re-configure or repair themselves without the intervention of the operators. A direct field of application is within the maintenance spectrum. Having systems or machines capable of self-detecting or even self-repairing could represent a game-changer, in capital asset fields such as the mining industry in particular. This paper aims to investigate the possible benefits and challenges of self-engineering / self-maintenance concerning mining machines, specifically bucket-wheel ...self-engineering, self-maintenance, maintenance operations, mining industry, bucket-wheel excavator, gearbox revitalizationSteven Manders, Milorad Pantelić, Vladimir Milisavljević, Alberto Martinetti.

Novel Methods in Multiple Criteria Decision-Making Process (MCRAT and RAPS)—Application in the Mining Industry
Multiple criteria decision making (MCDM) is a supporting tool which is widely spread in different areas of science and industry. Many researchers have confirmed that MCDM methods can be useful for selecting the best solution in many different problems. In this paper, two novel methods are presented and applied on existing decision-making processes in the mining industry. The first method is multiple criteria ranking by alternative trace (MCRAT) and the second is ranking alternatives by perimeter similarity (RAPS). These ...Katarina Urošević, Zoran Gligorić, Igor MIljanović, Čedomir Beljić, Miloš Gligorić.

Flyrock induced by blasting in surface mining
Milanka Negovanović, Lazar Kričak, Snežana Ignjatović, Stefan Milanović, Jovan Marković, Nikola Simić, Rade Šarac (2022)Miniranje predstavlja i dalje najefikasniji i najjeftiniji način eksploatacije velikih količina čvrstih mineralnih sirovina na površinskim kopovima. Energija eksplozije se koristi za fragmentaciju čvrste stenske mase do zahtevane granulacije. Pored pozitivnih efekata miniranja, postoje i određeni neželjeni efekti svakog procesa miniranja koji se mogu javiti, a to su: potresi tla, razletanje komada stene, vazdušni udari, otrovni i zagušljivi gasovi i prašina. Razletanje komada stene je nekontrolisano izbacivanje fragmenata odminirane stenske mase i predstavlja jedan od glavnih izvora materijalne štete ...Milanka Negovanović, Lazar Kričak, Snežana Ignjatović, Stefan Milanović, Jovan Marković, Nikola Simić, Rade Šarac.

Possibilities of retro-digitalized German-Serbian Mining Dictionary
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 ...Biljana Lazić, Olivera Kitanović, Ivan Obradović.

Development of Integrated Fuzzy Model for Mine Management Optimization
Miodrag Čelebić, Sanja Bajić, Dragoljub Bajić, Dejan Stevanović, Duško Torbica, Vladimir Malbašić (2023)Technoeconomic, environmental and safety criteria generally affect the management of metallic and non-metallic mining operations. The first basic question that needs to be addressed when planning ore mining is which methods are adequate and what is the optimal mining technology? Due to the complex geologic framework of ore deposits, geological exploration has rendered synonymous the inherent uncertainties, vagueness, and inaccuracies. As a result, subjective evaluation by engineers and expert experience have become increasingly important. Given that the natural language ...Miodrag Čelebić, Sanja Bajić, Dragoljub Bajić, Dejan Stevanović, Duško Torbica, Vladimir Malbašić.
