Field Zoning According to the Possibility of Applying Mechanized Excavation With a Longwall Below the Town of Gacko
Dragana Savić, Jelena Majstorović (2021)Mogućnost povećanja korišćenja resursa čvrstog energetskog goriva u procesu rešavanja energetske krize koja je sve prisutnija u širem regionu, jeste pravi izazov rudarske nauke. Podzemna eksploatacija uglja je složen proizvodni proces koji objedinjuje više tehnoloških postupaka u jedinstvenu celinu: izradu podzemnih prostorija, otkopavanje, transport i izvoz, ventilaciju proizvodnog sistema, odvodnjavanje, servisiranje objekata i sistema, zaštitu i sigurnost rada. Jedan od osnovnih problema koji prati podzemnu eksploataciju uglja jeste stabilnost podzemnih prostorija i deformacije na površini terena, jer su podzemne ...mehanizovano otkopavanje, mehanizovano široko čelo, zoniranje terena, modeliranje, stabilnost, sleganje, stabilnost kosinaDragana Savić, Jelena Majstorović.

Razvoj rudarstva i metalurgije olova i cinka u rudniku ,,Trepča’’ – Stari Trg
Posle seobe Srba 1690. i 1735. godine, dolazi do prestanka eksploatacije rudnika na prostoru sadašnje Srbije i nakon zastoja od blizu 200 godina, aktivirana je rudarsko-metalurška delatnost u Srbiji u drugom kvartalu 20. veka. Prve koncesije otkupili su Englezi 1926. godine, zatim se aktiviraju rudnici u Starom Trgu (1927.), Kišnici (1927.), Ajvaliji (1930.), Novom Brdu (1933.), a u Zvečanu počinje da radi Flotacija (1930.) i Topionica sa Rafinerijom olova (1939.).

Application of the Fuzzy theory in the evaluation of operating parameters of auxiliary mechanization on open-cast coal mine, case study: pipelayers
Achieved operating parameters are the main indicator of the work quality and selection of mining machines. The effectiveness of a coal mine is correlated with the availability of basic and auxiliary machines. The main task of auxiliary machines in lignite mines is to achieve optimal working conditions. From an economic point of view, auxiliary machines generate up to 20% of the lignite mines' total costs. These are the primary reasons for analyzing their current work and making decisions in ...Stevan Djenadić, Miloš Tanasijević, Filip Miletić, Predrag Jovančić.

Environmental Noise Impact Assessment for Large-Scale Surface Mining Operations in Serbia
Noise emissions are a significant environmental impact caused by the mining industry in all technological phases of surface mining, mineral processing, and waste disposal. This paper presents the role of noise impact assessment and control in large-scale surface mining operations. Mine planning develops the model of mining operations, ore excavation, and waste dumping scheduling and processing rates, including spatial distribution of mining activities. Such a level of mine planning requires an environmental impact assessment study. This can be achieved ...Uros Pantelic, Petar Lilic, Aleksandar Cvjetic, Nikola Lilic.

Interaction of sodium dodecylsulfate (SDS) with homoionic montmorillonites: adsorption isotherms and metal-ion release
The interaction of dodecylsulfate anions (DS−) with homoionic Ca-, Mg-, Ni-, Cu-, Cd-, Pb- and Fe-montmorillonites were investigated. Mg- and Cd-montmorillonite do not adsorb DS−, and an anion exchange at the edges of the clay mineral does not take place. Three different adsorption processes are identified on the other montmorillonites: i) Fe-montmorillonite is covered with amorphous iron hydroxide, and DS−-anions are bound at positively charged sites. ii) On Ca- and Pb-montmorillonite DS− is precipitated as Me(DS)2. iii) On Ni- ...M.

Numerical Modeling and Simulation of the Effectiveness of Groundwater Source Protection Management Plans: Riverbank Filtration Case Study in Serbia
The paper describes the establishment and testing of an algorithm for developing sustainable management plans associated with groundwater source protection against potential pollutants and discusses the effectiveness of individual systems. The applied methodology pertains to groundwater resource management, particularly those cases that involve riverbank filtration. Namely, groundwater (numerical) modeling is employed to examine the groundwater regime and balance, as well as to create protection systems and illustrate their effectiveness. Particle tracking analysis is used to study pollutants’ travel and ...Dušan Polomčić, Dragoljub Bajić, Bojan Hajdin, Dragan Pamučar.

Status and tendencies under development and application of underground coal gasification-UCG
Podzemna gasifikacija uglja u Svetu poslednjih decenija doživljava znatnu ekspanziju u istraživanju i razvoju zbog uveliko iskorišćenih ležišta uglja i loših ekoloških efekata (pri sagorevanju u TE) na životnu okolinu. Srbija ima znatne rezerve uglja, a kada bi se za PGU koristile samo vanbilansne rezerve i otkopni ostaci bilansnih, jasno je kakvi bi bili ekonomski (a i energetski i ekološki) efekti. U radu su sagledane aktivnosti u Svetu na tom planu, pa smatramo da ima smisla i potrebe za primenu ove ...David Petrović, Lazar Kričak, Stefan Milanović, Jovan Marković, Nikola Simić.

Karst wastewater as a high quality, renewable and within the circular economy water resource
Jovana Nikolić, Vesna Ristić Vakanjac (2021)High quality drinking water in it’s natural state is becoming less and less available to the human population. Based on the expected climate changes, it is considered that this resource will be less in the world but also in our region. Also, the accompanying polluting components that exceed the maximum allowable concentration are increasingly present in the waters. Even after the water treatment, it happens that some components are still in the drinking water, which adversely affects human health. ...Jovana Nikolić, Vesna Ristić Vakanjac.

Application of the principle of circular economy to the thermal groundwater, the example of the municipality of Bogatić
There are about 360 locations of thermal and thermo-mineral waters in Serbia, whose water temperatures range from 14 to 98°C, which ranks Serbia as the richest European country in geothermal energy. The mentioned water resources (thermal and thermomineral waters) are used, mostly, for therapeutic purposes in spas and sports and recreational centers. The main problem that is present is the fact that they are not used in a rational and efficient way. The paper will give examples territorially related ...Marija Jovanović, Vesna Ristić Vakanjac.

Speleo‐morphology and tectonic processes – What can be seen in slowly deforming regions?
Ana Mladenović, Jelena Ćalić (2022)There are a lot of methods used to determine tectonic process active in a region, and they vary depending on the purpose of the research. However, a number of them cannot be used in slowly deforming regions, because the effects of active tectonic process on the rocks in such regions could be negligible. This is especially true for the recently active tectonics in such regions, since most of the recently active tectonic structures never reach the surface. Because of ...Ana Mladenović, Jelena Ćalić.

Karst groundwater quantity assessment and sustainability: the approach appropriate for river basin management plans
Veljko Marinović, Zoran Stevanović (2019)As a result of the fact that karstified rocks can accumulate large amounts of high-quality groundwater, karst aquifer is considered, throughout the world, one of the most important types of aquifers. Due to their high permeability, but also vulnerability to pollution, these precious groundwater resources need to be properly evaluated and protected. Taking into account heterogeneity and complexity of the karst environment, it is difficult to propose a uniform algorithm for managing karst groundwater, which causes the necessity to ...Upravljanje karstnim podzemnim vodama, Pritisci na kvantitet voda, Plan upravljanja vodnim resursima, Bosna i Hercegovina, SrbijaVeljko Marinović, Zoran Stevanović.
