Abstract

Prilikom izrade projektne dokumentacije najvažniji podatak za investitore predstavlja količina
i iskorištenje rezervi mineralnih sirovina. Pri proračunu rezervi mineralnih sirovina potrebno
je uzeti u obzir mnoge veličine, no jednako je važno koristiti metodu proračuna rezervi koja
odgovara značajkama ležišta i osigurava pouzdan rezultat. Ležišta arhitektonsko-građevnog
kamena, na kojima se blokovi pridobivaju podzemnom eksploatacijom, posjeduju određene
specifičnosti koje se moraju poštovati pri proračunu eksploatacijskih rezervi. U ovom radu za
proračun rezervi arhitektonsko-građevnog kamena na dijelu ležišta „Kanfanar-jug“, na kojem
se kameni blokovi dobivaju podzemnom eksploatacijom, korišten je računalni program
GEOL_DH. Spomenuti program bazira se na metodi blokova, kod koje se mineralna sirovina
dijeli na blokove odgovarajućih dimenzija, koji se potom postavljaju u željenom pravcu koji
osigurava najbolje iskorištenje mineralne sirovine. Cilj rada je prikazati osnove metode
optimizacije geometrije iskopa i proračuna rezervi koji osiguravaju optimalno iskorištenje
mineralne sirovine u ležištu.

Abstract: During the preparation of project documentation on the mineral resources, the most relevant
data for investors is the amount of the reserves and utilization of mineral resources. When
calculating the reserves of mineral resources, many parameters must be taken into account,
but it is equally important to use the calculation method that suits the nature of deposit and
provides reliable results. Dimension stone deposits on which blocks are acquired by
underground exploitation, have certain peculiarities that must be respected while calculating
the mineral reserves. In this paper, for the estimation of the dimension stone reserves on the
part of the quarry "Kanfanar-south", where the stone blocks are excavated by underground
mining, computer program GEOL_DH is being used. This program is based on the blocks
method, in which the mineral resources are divided into the blocks of the adequate
dimensions, which are then placed in the desired direction to ensure the best utilization of
mineral resources. The aim is to present the basics of optimization method for geometry of
underground exploitation that ensures optimal utilization of mineral resources in the deposits.
