Effectiveness Analysis of Different Bucket-wheel Excavators
Coal production in open-pit lignite mines in the Republic of Serbia is performed with continuous work systems. In addition to coal production, the same systems are used for the exploitation of large quantities of overburden. According to the reliability concept, continuous systems are in linear connection. If the failure occurs in one part of the system, that will produce a downtime of the entire system. The initial and most important factor of continuous systems is the bucket-wheel excavator.

Cutting elements of bucket wheel excavators in lignite opensast mines: Methodology and performed solutions
Dragan Novaković, Predrag Jovančić (2016)Bucket and cutting elements geometry (teeth and hardened steel) have very powerful impact on effective operation of bucket wheel excavator, and that`s why, problems of optimal geometry of elements in specific conditions always are of special interest in mining science and technique.

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.

Uticaj geološke neizvesnosti u razvoju rudarskih projekata
Rudarstvo je industrija koja se nosi sa različitim vrstama neizvesnosti i rizika zbog svoje prirode i specifičnosti. Neizvesnost u rudarstvu može poticati iz različitih izvora i uticati na različite aspekte rudarskih projekata. Kao jedan od dominantnih faktora, ističe se geološka neizvesnost. Geološka neizvesnost igra ključnu ulogu u rudarstvu i može značajno uticati na procenu resursa i rezervi, planiranje eksploatacije, ekonomsku isplativost i upravljanje rizicima. Ova neizvesnost se ne može eliminisati, ali se uz primenu adekvatnih standarda i zakona može ...... nadalje tretira kao nepromenljiva činjenica. Takav pristup ne ukazuje da je to samo procena (makar ocenjena i kao najbolja), već i da interpretacija može biti pogrešna i da je moguća pojava različitih rezultata. Geolozi znaju da je njihovo poznavanje i tumačenje geceoloških procesa u stvaranju ležišta ...
... Imajući ovo u vidu, Royer (Royer PS., 2000) napominje da jedan od prvih koraka u procesu planiranja, treba da bude identifikacija i procena uticaja neizvesnosti.

Design of the Opencast Coal Mine Drmno Dewatering System
Development of mining in the opencast mine Drmno from Kostolac basin in Serbia is carried out in the increasingly complex geological and hydro geological conditions with the decline of the coal seams to the alluvial part of Europe's largest river Danube. Greater depth and inflow of groundwater significantly increase costs for dewatering facilities construction with the requirement for optimizing of this more and more important surface mining process.

Dynamic and Static Elastic Properties - Laboratory Investigations of Metamorphites of the "Vranjska Banja" Series
Metamorphites of the series “Vranjska banja” built predominantly of high crystallinity schist series, alternately layered double mica, gneiss, leptonite and micaschist. For the construction of the “Prvonek” dam were carried out laboratory investigations of dynamic and static elastic properties on micashist and gneiss samples in the perpendicular and parallel direction to the foliation. These investigations provided monitoring of the rock mass anisotropy properties and greater reliability of the design parameteres. As the design of mining and construction facilities becomes ...Jelena Majstorović, Bojan Dimitrijević, Suzana Lutovac, Snežana Savković, Miloš Gligorić.

Analiza sistema odvodnjavanja površinskog kopa Drmno od podzemnih voda sa severnim savršenim ekranom
Izrada nesavršenog ekrana do drugog sloja uglja na površinskom kopu Drmno, pored zadržavanja postojećih standardnih metoda odvodnjavanja od podzemnih voda linijama bunara, predviđena je poslednje decenije u celokupnoj rudarskoj projektnoj dokumentaciji. Iz objektivnih i subjektivnih razloga njegova realizacija nije ostvarena do danas. U međuvremenu je, uz dodatna geološka istraživanja i promenu dinamike i parametara sistema površinske eksploatacije, došlo do određenih značajnih prostornih promena geoloških i rudarskih uslova u eksploatacionom polju.

Ventex: an expert system for mine ventilation systems analysis
roblems relating to mine ventilation systems analysis are usually of a very complex nature. They involve the estimation of numerous interdependent parameters pertaining to the network status, ventilation status, ventilation system stability, air current losses, climate conditions, gas state, fire risk and dangerous dust pollution risk. The solution to these problems relies, to a great extent, on numerical methods.
