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 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.

The Content of Toxic Metals in Agricultural Produce near a Coal Mine: Case Study KCB in Lazarevac, Serbia
Праћење и анализа концентрација токсичних метала (олово и кадмијум) у земљишту и усевима указују на то да пољопривредно земљиште у Србији углавном није загађено, а квалитет земљишта је природно добар. 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. Локације овог типа морају бити редовно прати и процењује статус земљишта и усева. ...Ana Koprivica, Čedomir Beljić, Boris Vakanjac, Vesna Ristić Vakanjac, Marina Čokorilo Ilić.

Conversion of land areas after coal mine closure and reclamation
Otkopavanje uglja površinski i podzemno praćeno je degradacijom zemljišta, promenom formiranja predela i izmenom flore i faune. Od velikog značaja je razvoj novih naučno utemeljenih pristupa obnovljanje antropogeno poremećenih predela zasnovanih na formiranju rekultivacionih i rudarskih tehnologija. Apsolutno je neophodno obezbediti sveobuhvatno kvalitetno očuvanje zemljišnih i vodnih resursa i odrediti rekultivisano zemljište za novu namenu.
