  • Coal: exploration, reserves, and utilization

    Dragana Životić, Gligor Jovanovski, Vladimir Simić, Ivan Boev, Vesna Cvetkov, Petre Makreski, Dušan Polomčić, Vesna Ristić Vakanjac (2024)
    Coal exploration is a very demanding task, highly dependent on geological and economic factors and the utilization of coal. This lecture text includes information on a variety of geological techniques used in the exploration of coal and coal-bearing sequences, as well as on the calculation, assessment, classification, and reporting of coal resources and reserves. The main features of coal utilization and some environmental aspects are explained briefly. Special attention is paid to the by-products of coal utilization, their uses, ...

  • Effectiveness Analysis of Different Bucket-wheel Excavators

    Stevan Đenadić, Predrag Jovančić, Dragan Ignjatović, Miloš Tanasijević, Filip Miletić (2021)
    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. It ...

    Објекти одводњавања површинског копа морају поуздано обављати своју функцију, а да су при томе економични. Једна од функцијуа им је и да спрече доток површинских вода у радну контуру површинског копа, као и да воде које доспеју у радну контуру, прихвате и спроведу до водосабирника, а затим је одатле одстране ван радне контуре површинског копа. Овим завршним радом је сагледано постојеће стање система одводњавања површинских вода на површинском копу лигнита Дрмно у 2024. години, и дато по мом мишљењу једно ...
