Hydrochemical indicators of groundwater flow in the area of “Čukaru Peki” Cu-Au underground mine in eastern Serbia
The physical and chemical properties of groundwater, together with the groundwater levels regime and rock hydraulic properties, are often used to understand and conceptualize the hydrogeological system. Prediction of the influence of mining works on groundwater, and vice versa, is a challenge due to significantly altered groundwater flow patterns in the raw materials exploitation areas in relation to natural conditions. Therefore, multiple parameters are assessed and monitored before and during exploitation to properly characterize and quantify the system for ...Nebojša Atanacković, Vladimir Živanović, Jana Štrbački, Veselin Dragišić, Ivana Cvejić.

Rudničke vode olovo-cinkovih ležišta u rudnom polju „Blagodat“ u jugoistočnoj Srbiji
Nebojša Atanacković, Veselin Dragišić, Vladimir Živanović, Ivana Cvejić, Saša Stojadinović, Ivana Jocić (2022)Rudno polje Blagodat sa više ležišta i pojava olovo-cinkovih ruda nalazi se u krajnjem jugoistočnom delu Srbije, blizu granica sa Bugarskom i Severnom Makedonijom. Eksploatacija ovog resursa vrši se podzemno u okviru rudnika Grot, ranije Blagodat. Prilivi podzemnih (rudničkih) voda u jamske radove rudnika Grot su visoki i iznose oko 130 l/s (septembar 2019), što ga trenutno svrstava u najovodnjenije rudnike sa podzemnom eksploatacijom u Srbiji. Nezavisno od njih, iz obližnjeg potkopa P-1 u ležištu Kula, ističe još 25 ...Nebojša Atanacković, Veselin Dragišić, Vladimir Živanović, Ivana Cvejić, Saša Stojadinović, Ivana Jocić.

Geochemistry of neutral mine drainage at sulfide deposits ‒ example of the „Grot“ Pb-Zn mine, South-Eastern Serbia
U ovom radu proučavan je hemijski sastav voda iz rudnika i izdvojeni su hidro-geohemijski faktori koji utiču na njegovo formiranje. Sakupljeno je 11 uzoraka vode sa 6 lokacija na području Krive Feje, kako bi se utvrdio njihov hemijski sastav. Analizom podataka utvrđeno je da su vode sa ovog područja visokog kvaliteta, HCO3--SO42--Ca2+ i SO42--Ca2+ tipa, sa neutralnom pH vrednošću. Koncentracije metala u ovim vodama (cinka, olova, barijuma, bakra i hroma) generalno su niske i većina uzoraka voda ispunjava kriterijume ...podzemne vode, kisele rudničke vode, hidrogeohemijski faktori, metali, PHREEQC modeliranje, indeks saturacijeSnežana Kretić, Jana Štrbački, Nebojša Atanacković.

Стабилизација косине приступног пута површинског копа ћерамиде
У југоисточном делу површинског копа Ћерамиде дошло је до формирања клизног тела у косини насипа приступног пута. Клизно тело се привремено стабилизовало и исто се врло брзо може променити услед повећаних количина падавина и инфилтрације веће количине воде у тело косине чиме би се драстично изменила физичко-механичка својства стенског материјала у телу насипа пута и стенског масива у залеђини косине.

Multiphase evolution of fluids in the Rudnik hydrothermal-skarn deposit (Serbia): new constraints from study of quartz-hosted fluid inclusions
This study presents and discusses first detailed petrographic, microthermometric and Raman spectroscopic data from quartzhosted fluid inclusions at Rudnik Zn-Pb-Cu-Ag skarn deposit (Serbia) and combines them with the information on skarnand ore paragenesis. Three periods in the metamorphic-hydrothermal history of the deposit are recognized: 1) the pre-ore prograde skarn period when garnet-clinopyroxene skarns formed, 2) the syn-ore period that encompasses a retrograde stage marked by epidote and zoisite and a quartz-sulfide stage characterized by quartz, pyrrhotite, sphalerite, galena and ...skarnovska ležišta, rudnik, fludine inkluzije, srpska kenozojska magmatska provincija, Zapadno Tetisjki metalogenetski pojasStefan Petrović, Ronald J.

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. With the development of computer technology these methods were incorporated as numerical routes in software packages, such as the mine ...Nikola Lilić, Ranka Stanković, Ivan Obradović.

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. More than 100 bulldozers have been hired ...Dragan Ignjatović, Predrag Jovančić, Stevan Đenadić, Ivan Janković, Ivica Ristović.

History of the development of the hydrodynamic model of the open pit mine “Drmno”, Serbia
With the creation of a hydrodynamic model, the need for it usually ceases until some next moment when the model needs to be updated and used for the set task for the necessary project documentation or dedicated studies. It is relatively rare that almost every year the model is improved and used for forecast calculations. The paper presents the basic characteristics and development of the hydrodynamic model of the open pit mine “Drmno” for 25 years.

Present Situation and Alternative Water Supply Solutions for Northern Vojvodina (Serbia)
The northern part of the Autonomous Province of Vojvodina is situated in the central and southeastern sectors of the Pannonian Basin. Drinking water supply is provided by groundwater abstraction from depths of 60 to 200 m. The quality of that water is poor, especially due to high concentrations of arsenic which most water supply systems do not remove. Current planning documents call for the construction of large regional water supply schemes on the banks of the Danube and Tisa ...Bojan Hajdin, Vesna Ristić-Vakanjac, Dušan Polomčić.

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.

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.

This paper focuses on the results of water shutoff operations using DSGA polymer gel in the Kelebija oil field. The methodology of candidate wells selection and the manner of performing the operation will also be included. The Kelebija oil field is characterized by a complex reservoir system with heterogeneous layers of different permeability and dual porosity, which led to the early breakthrough of water. For the last 25 years, average water cut was above 90%.

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.
