Идејно решење заштите површинског копа ,,Дрмно" од вода у периоду од 2030. године до краја експлоатације
Јован Киселчић (2024)Системи одводњавања на површинским коповима као и други технички системи морају успешно извршавати своју функцију и са свим својим елементима издржавати сва предвиђена напрезања,а при томе бити једноставни и економични.Функција система одводњавања је да спречи доток, пре свега, подземних вода у површински коп и да у одређеном времену испумпа задате количине воде.У овом раду приказани системи одводњавања на површинском копу ,,Дрмно" у периоу од 2023.године до краја експлоатације и то систем одводњавања подземних вода и систем одводњавања површинских вода.На ...... eJIČKTDOHNIDOBOJUPBHBOCT BOJIĆ H3 J[pMHCKeE H3JaHH JE OKO H H3HaJL MaKCHMAJIHO J\03BOJbeHe BpeJiHocTu oJ 1000 uS/cm; yKyrHH0 rBo»Klje (Fe) – oHo Iro KapakTepurre J[pMHckKy H3JlaH je noBehaH cajnp:xaj TBOxxXlja H MaHraHa y 3HauajHHM KOHICHTPpaHJaMa, OJL MaKCHMAJIHO J[O3BOJbeHHX KOHneHrTpanuja 3a ...

Prognoza operativne efikasnosti aktivnog podzemnog rudnika zasnovana na teoriji sivih sistema
Svetlana M. Štrbac-Savić (2016-06-10)Efikasnost predstavlja preduslov za opstanak svake rudarske kompanije, posebno u uslovima izuzetno konkurentnog trţišnog okruţenja kao što je to rudarska industrija. Efikasnost oznaĉava sposobnost kompanije da ispuni svoje kratkoroĉne ili dugoroĉne ciljeve. Operativna efikasnost se definiše kao odnos izmeĊu ulaznih parametara potrebnih za odvijanje proizvodnje i pokazatelja dobijenih proizvodnjom. U kontekstu rudarskog poslovanja, operativna efikasnost se odnosi na vreme potrebno da se mineralno dobro transformiše u novĉana sredstva.

The Fuzzy–AHP Synthesis Model for Energy Security Assessment of the Serbian Natural Gas Sector
Natural gas is used for the production of almost 20% of total energy today. The natural gas security of the Republic of Serbia is an urgent strategic, political and security issue. Serbia is one of the most vulnerable countries in Southeast Europe, because it only has one supply route. This study is a contribution to efforts to better understand the factors affecting energy security through the implementation of a new methodology based on the fuzzy–AHP synthesis model for measuring ...... ј Е − − ј Е − − ј Е − − ј Е − − ј Е − − ј Е − − ј Е − − ј Е ...

Gate Road Support Deformation Forecasting Based on Multivariate Singular Spectrum Analysis and Fuzzy Time Series
Luka Crnogorac, Rade Tokalić, Zoran Gligorić, Aleksandar Milutinović, Suzana Lutovac, Aleksandar Ganić (2021)Underground mining engineers and planners in our country are faced with extremely difficult working conditions and a continuous shortage of money. Production disruptions are frequent and can sometimes last more than a week. During this time, gate road support is additionally exposed to rock stress and the result is its progressive deformation and the loss of functionality of gate roads. In such an environment, it is necessary to develop a low-cost methodology to maintain a gate road support system. ...deformacije podgrade, lasersko skeniranje, višekanalna singularna spektralna analiza, prognoza, klasterisanje fuzzy vremenskih serija... on stage were also used for the forecasting purpose.

A Model for Determining Fuzzy Evaluations of Partial Indicators of Availability for High-Capacity Continuous Systems at Coal Open Pits Using a Neuro-Fuzzy Inference System
This paper presents a model for determining fuzzy evaluations of partial indicators of the availability of continuous systems at coal open pits using a neuro-fuzzy inference system. The system itself is a combination of fuzzy logic and artificial neural networks. The system availability is divided into partial indicators. By combining the fuzzy logic and artificial neural networks, a model is obtained that has the ability to learn and uses expert judgment for that learning.
