Funkcionisanje i uticaj epikarsta na režim, bilans i kvalitet podzemnih voda istočnog dela karstnog sistema Suve planine
Branislav Z. Petrović (2020)Epikarst je deo karstne izdani koji se nalazi u okviru nadizdanske zone i predstavlja kompleksnu tačku dodira i mešanja nekonsolidovanog materijala sa površine terena, ostataka karbonatnih stena izmenjenih korozivnim delovanjem vode, živog sveta i njihovih ostataka, koja je delimično zasićena podzemnom vodom. Kompletan sud o stepenu razvoja i prisustva epikarsta na nekom krečnjačkom terenu moguće je doneti uz multidisciplinarna i obavezna detaljna hidrogeološka istraživanja. Poligon za sprovedena istraživanja je bio karstni masiv Suve planine, koja u geološkom i geografskom smislu ...epikarst, karstni sistem, podzemne vode, procesi samoprečišćavanja, hidrohemijski i mikrobiološki procesi u podzemnoj vodiBranislav Z.

Tehnologija izrade i opremanje magacina eksploziva za potrebe ležišta bakra
Aleksandar Milojević (2024)Nakon radova otvaranja i početka eksploatacije, rudno telo bakra velikih rezervi zahteva i veliku količinu eksploziva da bi se ostvario zacrtan kapacitet. Samim tim, neophodno je izraditi funkcionalan magacin eksploziva koji će biti pristupačan svim horizontima i koji će moći da ispuni celokupni kapacitet svih horizonata. Obzirom da će se u magacinu skladištiti eksploziv, on mora ispunjavati specijalne uslove kako bi skladištenje bilo bezbedno.
