The optimization of auxiliary machinery in open-cast lignite mines: a case study of bulldozers
One of the most important prerequisites for the successful operation of the open-cast lignite mine is to carry out all the auxiliary works timely with the necessary quality. The most important and most commonly used auxiliary machines are bulldozers. Engaging time of bulldozers use is in direct relation with the coefficients of the time and capacity utilization of the continuous system for the excavation of coal and tailings, which indicates their importance. More than 100 bulldozers have been hired ...Dragan Ignjatović, Predrag Jovančić, Stevan Đenadić, Ivan Janković, Ivica Ristović.

Comparative analysis of karst water quality parameters of the Banja spring near Valjevo (Republic of Serbia)
Jovana Lončar, Jovana Mladenović, Vesna Ristić Vakanjac, Veljko Marinović, Branislav Petrović, Petar Vojnović, Radisav Golubović (2024)The monitoring of karst spring release regimes is becoming more and more relevant due to the fact that karst waters are of exceptional quality and most often it is only necessary to chlorinate these waters in order to use them for water supply. In addition to monitoring the discharge regime, it is certainly necessary to establish monitoring of quality parameters that are generally observed sporadically (seasonally or monthly). An example of a well-designed monitoring of quantitative and qualitative parameters ...Jovana Lončar, Jovana Mladenović, Vesna Ristić Vakanjac, Veljko Marinović, Branislav Petrović, Petar Vojnović, Radisav Golubović.

History of the development of the hydrodynamic model of the open pit mine “Drmno”, Serbia
With the creation of a hydrodynamic model, the need for it usually ceases until some next moment when the model needs to be updated and used for the set task for the necessary project documentation or dedicated studies. It is relatively rare that almost every year the model is improved and used for forecast calculations.

Utilizing sewage wastewater heat in district heating systems in Serbia: effects on sustainability
Marija Živković, Dejan Ivezić (2021)Transformation of the heating sector is recognized as being essential for ensuring reliable and afordable energy services provided with reduced consumption of energy sources and diminished impact on the environment and less import dependency. The possibility of utilizing energy sources that otherwise would be wasted needs to be considered and treated as a big advantage of district heating systems. Despite many advantages, sewage wastewater heat is still a mostly unused resource at the global level and a totally unused ...рекуперација топлоте из отпадних вода, систем даљинског грејања, топлотне пумпе, енергетске уштеде, емисија угљендиоксида, енергетска безбедност, СрбијаMarija Živković, Dejan Ivezić.

Challenges and Insights: Sequence Stratigraphy of Pannonian Coals in the Drmno Depression, Serbia
The application of sequence stratigraphy on coal beds worldwide has significantly contributed to the under¬standing of coal deposits and their origin. On the southeastern edge of the Serbian part of the Panno¬nian basin, there is a system of peri-Pannonian basins characterized by the appearance of Upper Miocene coal seams in the siliciclastic fill, which provides an ex¬cellent opportunity for testing sequence stratigraphy in young coal basins. In this study, sequence stratigraphy was applied to coals in the Drmno Depression, ...Anastasia Ninić, Dragana Životić, Dejan Radivojević.

Coupling of artificial intelligence methods in the development of hybrid intelligent systems
In this paper we present an approach which couples various artificial intelligence (AI) methods in the solution of complex problems that cannot adequately be solved by a single AI method. We argue that the resulting, hybrid intelligent systems (HIS) can be successfully implemented with the use of available AI software libraries. Different coupling methods are analyzed and a classification of hybrid systems based on the chosen method is given. Two case studies of hybrid systems used in mining engineering ...hibridni inteligentni sistemi, spregnuti sistemi, metode veštačke inteligencije, rudarske primene veštačke inteligencijeRanka Stanković, Ivan Obradović, Nikola Lilić.
