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.

Dejan N. Radivojević (2014-12-30)Predmet doktorske disertacije predstavljalo je rešavanje strukturno‐stratigrafskihodnosa miocenskih sedimenata na prostoru severnog Banata. U cilju regionalnogsagledavanja, korišćeni su svi raspoloživi geofizički i geološki podaci sa širegistražnog područja, odnosno iz celog Panonskog basena i susednog orogena. Osimklasičnih metoda primenjene su i savremene metode seizmostratigrafije,tektonostratigrafije i riftne sekvencione stratigrafije. Primenjene metode omogućilesu izradu modela progradacije ivice šelfa za ceo Panonski basen, modela uzajamnihveza između basena i geodinamičkog modela jugoistočnog oboda basena.Jezero Panon je većim delom zapunjeno prilivom sedimenata paleo‐Dunavom saseverozapada, odnosno ...Centralni Paratetis, Panonski basen, miocen, jezero Panon,seizmostratigrafija, sekvenciona stratigrafija, paleogeografija, geodinamika...

A Knowledge-Based Approach to Mine Ventilation Planning in Yugoslav Mining Practice
Ventilation system analysis is a complex process based on the calculation and analysis of numerous parameters. These problems can be successfully solved by the SimVent numerical package, but a full understanding and use of the obtained results require the involvement of an experienced specialist in the ventilation field. The solution was found in the creation of a hybrid system INVENTS, whose knowledge base represents a formalization of the expert knowledge in the mine ventilation field. In this paper, we ......
