  • Automated blasthole drilling in surface mining

    Milanka Negovanović, Lazar Kričak (2021)
    Све већи развој аутоматизације у рударској индустрији утицао је на увођење нових решења у области аутоматизације бушења минских бушотина на површинским коповима. Највећи светски произвођачи опреме за бушење развијају решења аутоматизације која омогућавају рударским компанијама да постигну најбоље резултате у погледу квалитета, продуктивности и оперативних трошкова. Решења из области аутоматизације бушења се крећу од операција даљинског управљања до потпуно аутоматизованог бушења, праћења података у реалном времену и разних специјализованих алата за управљање подацима који повећавају безбедност и продуктивност ...

  • Modern self-propelled surface drill rigs for drilling small diameter holes in mining and construction operations

    Milanka Negovanović, Lazar Kričak (2021)
    Приликом одређених рударских или грађевинских радова потребно је извршити минирање применом бушотина малог пречника. Раније, бушење бушотина малих пречника се изводило углавном ручним бушилицама или лаким лафетним бушилицама нa одређеним нoсачима. Проблеми у овим случајевима били су капацитет бушења, бушење већих дужина бушотина и посебно безбедност оператера на неприступачним теренима, где је његово присуство било неопходно. Данас постоје модерне самоходне бушилице за бушење минских бушотина малог пречника, које су у потпуности даљински управљане. Радио даљинска контрола омогућава да се ...

  • The impact of calculation of resources and reserves on mining activity in Serbia

    Jelena Zakonović, Katarina Urošević, Radmila Gaćina (2019)
    The appearance of interest of the world's most important mining companies i for investment in Serbia imposes the problem of harmonization of domestic legislation with foreign ones. In this paper, specific categorization and classification of mineral raw materials, which do not match in domestic and foreign practice, are treated. The existence of such a conflict of criteria in use for categorization and classification can lead to misunderstanding and create certain complications in business. The following sections outline some of ...
