Analiza i rešavanje problema pogona rotora rotornog bagera SRs2000 – put ka modernizaciji
Dragan Novaković, Predrag Jovančić (2017)Ovaj rad ima primarni cilj da definiše modernizaciju i revitalizaciju pogonske grupe rotora bagera SRs 2000 kako bi se obezbedilo povećanje pouzdanosti bagera, a time i povećanje vremenskog i kapacitetnog iskorišćenja i smanje troškovi održavanja. Sekundarni cilj, i ne manje važan, je unifikacija elemenata kako pogonske grupe tako i ostalih sklopova predviđenih za buduću modernizaciju i revitalizaciju na svim bagerima SRs 2000 koji rade na površinskim kopovima Elektroprivrede Srbije.Dragan Novaković, Predrag Jovančić.

A Fuzzy Expert Model for Availability Evaluation
Each technical system within itself carries the great potential danger of possible occurrence of failure and damages. Mining machines are characteristic by great investment values, costs of unplanned shutdowns, complex working conditions, and environment and workers hazards. Systematic monitoring of the mining machinery is of great importance for the management of the mining companies. Availability is the overall concept of quality of service. Includes information regard to operating state, an idle state, a standby state and shut down. The ...... are: R(D-Lib.) = 0.06/exc,0.62/good,0.32/avr; M(D-Lib.) = 0.56/good,0.44/avr; S(D-Lib.) = 0.4/good,0.3/aver,0.3/adeq; R(D-Drs.) = 0.34/good,0.56/aver,0.1/adeq; M(D-Drs.) = 0.12/good,0.68/aver,0.2/adeq; S(D-Drs.) = 0.56/aver,0.44/adeq; R(D-Cat.) = 0.52/exc,0.4/good,0.08/avr; M(D-Cat.) = ...

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.

A fuzzy-based decision support model for effectiveness evaluation - a case study of examination of bulldozers
Effectiveness evaluation is one of the basic components of engineering asset management and maintenance engineering in general. Effectiveness is an overall concept representing a measurement of quality of service level for the analyzed engineering system. This concept contains a series of partial indicators relating to time in operation and time for maintenance activities, as well as functional properties of the system. This article describes the analysis and structuring of partial indicators, as well as the development of a model ...Miloš Tanasijević, Predrag Jovančić, Dejan Ivezić, Uglješa Bugarić, Radiša Đurić.

Komparacija metoda XRF i ICP-MS na uzorcima uglja i produkata sagorevanja
Ugljevi niskog ranga – ligniti u Republici Srbiji predstavljaju glavnu energetsku sirovinu koja se koristi za proizvodnju električne energije. Rudarstvo u Srbiji doprinosi bruto dodatoj vrednosti sa 1,8% (2020; https://publikacije.stat.gov.rs/). Sagorevanjem ugljeva niskog ranga u termoelektranama generišu se velike količine elektrofilterskog pepela i pepela, koje često predstavljaju jedan od izvora zagađenja životne sredine usled sadržaja toksičnih elemenata. Dalja upotreba produkata sagorevanja zavisi od njihovog sastava i sadržaja toksičnih mikroelemenata. Svakodnevno sagorevanje lignita u termoelektranama uslovljava konstantan monitoring potencijalno toksičnih ...Branko Kostić, Dejan Prelević, Sabina Kovač, Ksenija Eraković, Dragana Životić.
