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.

Optimizacija utovarno-transportnih sistema u funkciji planiranja površinskog kopa
Mirjana V. Banković (2018-07-13)Profitabilna eksploatacija sve složenijih ležišta je težak zadatak koji zavisi odtemeljnog procesa analize, planiranja i projektovanja rudnika. Izvodljiv strateškiplan mora da zadovoljava društvena, regulatorna, tehnološka, geometrijska iekonomska ograničenja. Kako bi se postigao osnovni cilj, odnosno profitabilnost iodrživost rudarskog projekta na duži period, neophodno je unapređenjematematičkih modela i informatičke podrške procesima planiranja i optimizacijekoji će omogućiti efikasnu realizaciju ovih ciljeva...tehnološki model, integralni model, planiranje, optimizacija,utovarno-transportni sistem, neto sadašnja vrednost projekta... vedričaru se može videti iz njegove oznake, na primer: 710 17.513.0 − 16.0 gde su: E – bager vedričar (nemački Eimerkettenbagger) R – gusenični uređaj za kretanje (oznaka bez R predstavlja šinski uređaj) s – obrtni bager 710 – zapremina vedrice, litara 17.5 – otkopna visina; m 13.0 – otkopna dubina; ...

Избор методе подземног откопавања на примеру лежишта бакра
Mилош Глигорић (2024)Тема овог завршног рада је избор методе откопавања у подземном руднику бакра. Рад је подељен на четири поглавља. У првом поглављу дат је приказ општих података и геолошких карактеристика ширег подручја и лежишта. Детаљан опис отварања и припреме лежишта за откопавање представљен је у другом поглављу. У трећем поглављу дат је опис све три варијанте изабране методе за запуњавањем откопаног простора, са освртом на количину захваћене руде, трошковима експлоатације као и динамиком откопавања.
