David Petrović, Lazar Kričak, Milanka Negovanović, Stefan Milanović, Jovan Marković, Nikola Simić, Ljubisav Stamenić (2019)In the name of a better and safer energy future, it is our responsibility to focus our knowledge and activities to save on imported liquid and gas fossil fuels, as well as coal on which energy security of Serbia is based. The rationalization in the use of available energy resources certainly positively affects economy and the environment of a country. This paper indicates motivations for the application of the underground coal gasification process, as well as surface gasification for ...... UCG process as a way of obtaining a suitable and useful energy source, some of the advantages are: — the absence of heavy mining in underground, as well as in surface mining conditions, — minimum costs of transporting gas to consumers, — significantly lower cost of the final product (normalized ...

Highway construction in fossil landslides zones – Lessons learned from the Grdelica Gorge, Serbia
Landslides are common on roads, which directly affect the flow of traffic and the connection and functioning of the population in surrounding area. Therefore, it is necessary to investigate them in the shortest possible time and to determine and carry out the remediation solution. Functionality of the state roads is immensely important so it is necessary to ensure that the traffic is maintained during remediation activities. Therefore, design solutions and remediation execution technology should be adapted to these requirements. ...Biljana Abolmasov, Marinos Skempas, Svetozar Milenković, Janko Radovanović, Miloš Marjanović.

Regional rockfall exposure assessment, experience from Serbia
Rockfalls are common in hilly and mountainous areas, especially along roads with engineered slopes and cuts. Such is the case for most of the state and local road routes in Central, Serbia, which was the subject in this case study. A road network of 276 km covering roughly 1700 km2 between the cities of Kraljevo, Čačak and Ivanjica is presented. Assessing of such wide areas needs to be conducted from large to site-specific scale, i.e., using GIS spatial tools ...Miloš Marjanović, Biljana Abolmasov, Uroš Đurić, Jelka Krušić, Snežana Bogdanović.

Komparativna analiza završnih kontura površinskog kopa Drmno
Definisanje optimalne završne konture površinskog kopa od suštinskog je značaja za ostvarivanje strateških ciljeva u razvoju rudarskih projekata. Savremeni programski paketi i metode za optimizaciju granica kopa, zasnivaju se na pronalasku završne konture koja obezbeđuje maksimalan profit. U slučaju površinskih kopova uglja, kod kojih osim profita postoji i čitav niz dodatnih kriterijuma i strateških ciljeva, princip optimizacije granica prema profitu, najčešće nije u potpunosti primenjiv.

Determining the Impact of Cutting Elements State on the Bucket–Wheel Excavator Vibration and Energy Consumption
Background There are two types of specifc sizes’ measurements. The frst is the measurement of energy consumption in a working technological process, and the second is the measurement of vibration, which is displayed over amplitudes of speed. There is an interplay between these two processes. Increasing the power consumption, the value of the vibration speed amplitudes increases. Purpose The process of the determination of machining parameters was based on minimizing the power consumption and vibration of the cutting tool, ...Filip Miletić, Predrag Jovančić, Miloš Milovančević, Miloš Tanasijević, Stevan Đenadić.
