Abstract

U Republici Hrvatskoj ležišta eruptivnog kamena su rijetka i ima ih svega desetak.
Značajna ležišta dijabaza nalaze se na Papuku unutar radlovačkog semimetamorfnog
kompleksa u blizini grada Orahovice. Ležište dijabaza „Žervanjska“ jedno je od ležišta sa
najnepovoljnijim eksploatacijskim uvjetima u Hrvatskoj, karakterizirano visokim
koeficijentima otkrivke gdje do posebnog izražaja dolazi optimizacija skidanja i
prebacivanja otkrivke. Skidanje i prebacivanja otkrivke je jedan od najzahtjevnijih poslova
u površinskoj eksploataciji jer traži velika ulaganja i uglavnom ne ostvaruje prihod iz
razloga što većina otkrivke završi na jalovištu. Radom se optimizira postupak
gravitacijskog transporta otkrivke do utovarno-transportne razine osnovnog platoa u
ovisnosti o širini pojasa otkrivke koja se skida u jednom zahvatu.

Abstract (english)

Abstract: Optimization of overburden removal and throwing is one of the most challenging jobs in
surface mining because it requires huge investments and usually does not return any profits.
In order to optimize excavation the process requires many calculations in technical and
economic terms. In Croatia deposits of igneous rocks are quite rare and there are only ten
of them. Significant deposits of diabase are in the mount Papuk area within a semi
metamorph complex near town Orahovica. Diabase exploitation deposit "Žervanjska" is
probably the toughest deposit for exploitation in Croatia, where it comes to the precise
optimization of excavation and throwing overburden.
