Optimizacija i planiranje površinskih kopova stohastičkim modelima
Dejan R. Stevanović (2015-05-29)Savremeno rudarstvo izloženo je stalnom trendu pogoršanja uslova poslovanja.Mogućnost ostvarenja ekonomskih i drugih ciljeva rudarskog projektakompromitovana je stalnim pogoršanjem kvaliteta ležišta na kojima se vršieksploatacija, kao i značajnoj dozi neizvesnosti povezane sa geološkim,ekonomskim i tehničkim parametrima proizvodnje. U ovako kompleksnimuslovima poslovanja, matematički modeli sposobni da odgovore značajnimizazovima, odnosno ponude optimalna rešenja kojima se garantuje maksimalnoispunjenje projektovanih ciljeva, nameću se kao neophodnost.Trenutni, konvencionalni pristup optimizaciji i planiranju površinskih kopovazasniva se na algoritmima, razvijenim sredinom prošlog veka čije je opšteobeležje deterministički ...površinski kop, planiranje, optimizacija, stohastički modeli, kontrola kvaliteta uglja, neizvesnost.... otkopani u prethodnim vremenskim periodima. − ≤ 0 (4.11) za svako t, n i l, pri čemu je: l - indeks blokova koji se nalaze iznad razmatranog i moraju biti prethodno otkopani, l = 1, 2, ..., L.

Sitni, ali bitni: uloga sitnih sisara, herpetofaune i mekušaca u rekonstrukciji pleistocenskih paleosredina
Fosilni ostaci životinja i biljaka imaju važnu ulogu u rekonstrukciji pleistocenskih paleosredina. U ovom radu opisan je značaj tri grupe životinja: sitnih sisara, herpetofaune I mekušaca. Mada je za rekonstrukciju važan sastav čitave asocijacije, nalasci pojedinih vrsta mogu biti dovoljno indikativni da otkriju tip staništa ili klimatske uslove. Posebnu teškoću pri rekonstrukciji paleosredina u Srbiji predstavlja činjenica da klimatske promene na Balkanskom poluostrvu nisu bile tako oštre kao u srednjoj i zapadnoj Evropi, pa ne postoji drastična razlika u ......

Uticaj utiskivanja gas-lift gasa na prenos mase i toplote
Branko Grubač (2019)Nakon uvođenja kontinualnog gas-lifta, primećen je porast proizvodnje tečnog naftnog gasa, TNG, u postrojenju za preradu gasa, kao jednog od finalnih proizvoda dobijenog iz fluida gaso kondenzatnih i rastvorenog gasa iz naftnih bušotina. Pretpostavljeno je da se prisustvom gas-lift gasa uspostavlja drugačija ravnoteža faza u odnosu na slučaj bez gaslifta, te da je gas-lift gas stripovao propan i butane iz tečne u parnu fazu, što je dovelo do povećanja prinosa TNG-a.

Overwiew of In-Pit Crushing & Conveying Technology in Open Pit Mines
The conditions under which contemporary surface mining operations is carried out obviously becoming increasingly complex. In such complex conditions, the optimization of haulage systems as the technological phase with the largest share in the total operating costs, is very important from the aspect of achieving profitability of the mining project. In a large number of cases, the application of traditional haulage systems with trucks (as the most dominant type of haulage in open pit mines) does not lead to ...Ali Nasirinezhad, Dejan Stevanović, Dragan Ignjatović, Petar Marković.

Geotechnical zoning of the terrain along the first section of E-80 highway in Serbia – SEETO route 7
Part of E-80 highway that passes through Serbia (from the city of Nis to the administrative border Merdare) is 77 km long. The highway is divided into two sections: the first from Nis to Plocnik (39.4 km long) and the second from Plocnik to the administrative border with Kosovo. The route is designed through a typical plain and hilly terrain in which different geological units are dominant: crystalline schists, neogene sediments of foothills and quaternary sediments in the valley ...... planned structure construction at the highway route (bridges, tunnels, excavations, cuts, embankments etc.). 5 REFERENCES Hsai-Yang, F. and John, L.

Adaptive neuro-fuzzy prediction of operation of the bucket wheel drive based on wear of cutting elements
The capacity of the rotor excavator depends largely on the operation of the subsystem for digging. There is a great contribution to the correct and sharp teeth when the capacity is the highest. In the function of time, the teeth become clogged due to abrasive wear, or changes in their geometric shape. To analyze the bucket wheel drive in depend on wear of the cutting elements in this study adaptive neuro fuzzy inference system (ANFIS) approach was implemented. ANFIS ...Filip Miletić, Predrag D.

Fuzzy expert analysis of the severity of mining machinery failure
Mining machinery failure is almost an everyday occurrence. Usually the failures bare certain consequences, which require additional financial costs to repair and restore the system to its operational state. The consequences are viewed through negative and damaging effects a failure has on the machine, health and safety of the employees, work environment, and on the environment. The removal of the consequences of the failure requires additional financial investment, which has a negative impact on the company’s business. In order ...Dejan V.
