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 ......

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.

Tracking of the temporal dependency of fading of the human footprint temperature contrast
In certain situations, it is extremely important to determine the exact time “someone” entered or crossed the forbidden zone of a military or strategic installation, a red zone of radioactive, chemical, or biological contamination, a bank or similar structure. Standard security measures include ordinary video surveillance using cameras that operate in the visible range of the electromagnetic spectrum, as well commercial thermal imaging cameras [1, 2]. The paper presents the results of experiments that suggest another possible use of ...Stevan Đenadić, Ljubiša Tomić, Vesna Damnjanović, Darko Vasiljević, Danica Pavlović.

P-T analiza uglja RB Kolubara
Rada Vitomir (2024)Rudarski basen Kolubara predstavlja jedno od najvažnijih ležišta lignita u Republici Srbiji i ključni je faktor u snabdevanju zemlje energijom. Kvalitet uglja iz ovog basena direktno utiče na efikasnost termoelektrana i zadovoljenje energetskih potreba. U ovom radu, opisan je značaj tehničke i elementarne analiza uglja kako bi se utvrdili fizičko-hemijski parametri uglja iz Rudarskog basena Kolubara. U drugom delu rada dat je opis P-T analize uglja i njen značaj za ocenu mogućnosti čišćenja uglja. Takođe, dati su i rezultati ...... 7-14% relativno lako, ugljevi međuproiuzvodom od 14-21% se teško čiste a ugljevi sa udelom međuproizvoda preko 21% su nesposobni za čišćenje. g S B B B N G T M ~“ e UGALJ A UGAU SE LAKO ČISTI.

Environmental flows and demands for sustainable water use in protected karst areas of the Western Balkans
Karst terrains cover some 30% of the Western Balkans, where rich karst aquifers represent the main source of potable water supply and ensure the development of local economies and tourism.

Determination of Mechanical Properties of Altered Dacite by Laboratory Methods
This paper presents a methodology for determining the uniaxial and triaxial compressive strength of heterogeneous material composed of dacite (D) and altered dacite (AD). A zone of gradual transition from altered dacite to dacite was observed in the rock mass. The mechanical properties of the rock material in that zone were determined by laboratory tests of composite samples that consisted of rock material discs. However, the functional dependence on the strength parameter alteration of the rock material (UCS, intact ...... tics of quartz and biotite. Figure 2.
