Valorization of non-balanced coal reserves in Serbia for underground coal gasification
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 ......

A multi-criteria approach for assessing the potential of renewable energy sources for electricity generation: Case Serbia
When assessing the potential of renewable energy alternatives for electricity generation, it is necessary to implement a multi-perspective approach that includes economic, technical, environmental, and socio-political criteria. For the evaluation of criteria and alternatives, the Fuzzy Analytical Hierarchy Process (FAHP) method is applied. The obtained weights are formed according to the values of energy indicators and expert judgments. The use of a fuzzy numerical value scale for the assessment of expert judgments and energy indicators provides a more sensitive ...... concerning 4 sub-criteria (SC): 6 B. Pavlović, D. Ivezić and M.

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.

The Importance of Geotechnical Investigations for the Construction of Transfer Station „Prelići“ on Landfill in Cacak – Serbia
For the purpose of the facilities construction within the transfer station „Prelici“ in Cacak, specific geotechnical investigations were carried out based on which the technological project with the facilities schedule was developed. Significant deviations in relation to the presented results were determined during earthworks, so the additional geotechnical investigation works were carried out. Since the new investigation works have determined a different cross section of the terrain, it was proposed to move the planned facilities which led to the ...... , Coric, S., Basaric, I. and Jankovic, J.

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.

Validation of vulnerability assessment by means of the Time Dependent, Model: case study from the Slovenian karst catchment
Groundwater vulnerability assessment methods are continuously being developed and existing methods are very often modified to provide better simulation of natural protection conditions and more objective results. Most frequently used methods are based on calculation of predefined parameters influencing water infiltration and underground flow, which can often lead to bias conclusions related to vulnerability evaluations. Some other methods, like the Time Dependent Model (TDM) are based on an approach, where parametrization is obtained at the final stage of the ...Ocena ranjivosti podzemnih voda, karstne podzemne vode, TDM metoda, delineacija sanitarnih zona, Slovenački karstVladimir Živanović, Nataša Ravbar, Igor Jemcov.

Analiza seizmičkog dejstva eksplozije pri miniranju na primeru izrade tunela Golubac kod Golupca
Savremeno rudarstvo, a pogotovo masovna eksploatacija metaličnih ležišta, ne bi se mogla zamisliti bez primene eksploziva. Rudarstvo je privredna grana, gde su eksplozivi našli najširu primenu za eksploataciju čvrstih mineralnih sirovina. Primena energije eksploziva dovodi do poboljšanja tehničkoekonomskih pokazatelja pri eksploataciji mineralnih sirovina, ali i do pojave negativnih efekata koji prate radove na miniranju. Eksplozivni materijali u rudarstvu, geologiji i drugim delatnostima, svojim dejstvom narušavaju prirodnu sredinu u vidu drobljenja, razbacivanja komada stene, vazdušnih udara, pojave sezmičkih efekata, pojave ...Suzana Lutovac, Miloš Gligorić, Jelena Majstorović, Luka Crnogorac.

The Content of Toxic Metals in Agricultural Produce near a Coal Mine: Case Study KCB in Lazarevac, Serbia

Због тога су таква земљишта погодна за органску пољопривреду. Сви уочени случајеви контаминације токсичним металима су само локалне природе, а резултат су ђубрива и пестицида, комуналног отпада, издувних гасова, оближњих производних објеката, топионица, рудника, јаловишта итд.
