Coal homogenization stockyard sizing “Tamnava – Zapad” case study
... interest are the lower heating value and sulphur content, but other parameters are also an option (iron or mercury content, ash content...) [Ignjatović et al. 2007]. When the anticipated quality range of the observed parameter is small, the stockpiling conditions (number of layers, size or length ...
... (Germany) the leading parameters for coal stockyard homogenization are heating value, at the Profen pit, and iron content at the Schleenhain pit [Ignjatović et al., 2007]. Thus different coals, even from pits located close to one another, have different qualities and are homogenized according to different ...
... When quality is assessed based on lower heating value, the acceptable range for a power plant, as the end user, is considered to be ±500 kJ/kg [Ignjatović et al, 2007, Stevanović et al, 2015]. By observing the standard deviation, a diagram can be plotted where the number of layers is given as a function ...Božo Kolonja, Dinko Knežević, Ranka Stanković, Dejan Stevanović, Detlef Trummer.

Sustainable Modularity Approach to Facilities Development Based on Geothermal Energy Potential
The study presented in this paper assessed the multidisciplinary approach of geothermal potential in the area of the most southeastern part of the Pannonian basin, focused on resources utilization. This study aims to present a method for the cascade use of geothermal energy as a source of thermal energy for space heating and cooling and as a resource for balneological purposes. Two particular sites were selected—one in a natural environment; the other within a small settlement.

Simple 2D gravity–density inversion for the modeling of the basin basement: example from the Banat area, Serbia
We have developed a technique to calculate lateral density distribution of the sedimentary basin basement by combining linear gravity–density inversion and 2D forward modeling. The procedure requires gravity anomaly data, depth-to-basement data and density data for the sediments (density–depth distribution). Gravity efect of density variations in the basement was extracted from the total gravity anomaly by removing the joint efect of the sediments with vertical density variations and homogeneous basement of average density contrast (calculated by 2D modeling). Gravity ...Ivana Vasiljević, Snežana Ignjatović, Dragana Đurić.

Self-Engineering: Possibilities for Maintenance Operations in the Mining Machines Industry
Self-engineering is a relatively new branch of knowledge that aims to understand how systems could “autonomously” re-configure or repair themselves without the intervention of the operators. A direct field of application is within the maintenance spectrum. Having systems or machines capable of self-detecting or even self-repairing could represent a game-changer, in capital asset fields such as the mining industry in particular. This paper aims to investigate the possible benefits and challenges of self-engineering / self-maintenance concerning mining machines, specifically bucket-wheel ...self-engineering, self-maintenance, maintenance operations, mining industry, bucket-wheel excavator, gearbox revitalizationSteven Manders, Milorad Pantelić, Vladimir Milisavljević, Alberto Martinetti.

Development of the Availability Concept by Using Fuzzy Theory with AHP Correction, a Case Study: Bulldozers in the Open-Pit Lignite Mine
Stevan Đenadić, Dragan Ignjatović, Miloš Tanasijević, Uglješa Bugarić, Ivan Janković, Tomislav Šubaranović (2019)Availability is one of the most used terms in maintainability engineering. This concept is used to denote: The quality of service of an engineering system, i.e., machines, weak points’ analysis, asset management, as well as making decisions in the process of life cycle management. Availability is an overall indicator and contains partial indicators that are oriented towards reliability, maintenance, and logistical support. Availability presents a variable value and changes in time and space.

Утицај похабаности резних елемената роторног багера на ниво вибрација погона за копање
Филип Милетић (2023)У докторској дисертацији је анализиран утицај похабаности резних елемената роторног багера на потрошњу електричне енергије и ниво амплитуде вибрација погона за копање. Креиран је модел који у функцији стања резних елемената дефинише зависност разматраних физичких феномена. За развој модела примењене су једначине теорије осцилација и Ватметарска метода [1] којом се одређује потрошња електричне енергије. За верификацију модела извршена су мерења на роторном багеру SRs2000.32/5+VR ангажованом на откопавању откривке на површинском копу Тамнава–Западно поље. Обављено је пет мерења.
