Research and exploitation of carbonate raw materials in the "Vrebac" deposit near Gospić : master’s thesis

U radu je obrađen prijedlog istraživanja i eksploatacije ležišta „Vrebac“ kod Gospića u cilju proračuna rezervi karbonatne sirovine za industrijsku preradu. Obrađen je prijedlog istraživanja ležišta „Vrebac“. Opisane su geološke i druge značajke istraživanog područja. Topografske karte u rasterskom obliku su korištene kao podloga za izradu situacijske karte ležišta, vektorskog oblika. Na temelju važeće zakonske regulative i poznatih podataka o području, dan je prijedlog istražnih radova, određene su granice rezervi te visina i širina ležišta. Izrađeni su: 3D model terena i 3D model granica rezervi, koristeći program Bentley Microstation. Obrada prostornih veličina, metodom triangulacije, i generiranje podataka izvedeno je u programu Bentley Inroads. Proračun rezervi karbonatne sirovine proveden je metodom modeliranja i metodom paralelnih vertikalnih presjeka koji su generirani iz 3D modela. Napravljena je usporedba izlaznih rezultata proračuna te su izvedeni zaključci o pouzdanosti primijenjenih metoda.The paper deals with the research and exploitation of the deposit „Vrebac“ at Gospić in order to calculate the reserves of carbonate raw materials for industrial processing. The proposal for the study of the "Vrebac" deposit was elaborated. Geological and other features of the exploration area are described. Topographic maps in raster form were used as a substrate for creating a situation map of the depost, vector form. Based on valid legal regulations and well-known area data, a proposal for investigative work is given, the boundaries of reserves, the altitude and the width of the deposit are determined. Created: 3D model terrain and 3D model reserve boundaries, using the Bentley Microstation program. Spatial size processing, triangulation method, and data generation was performed in Bentley Inroads. Calculation of carbonate raw material reserves was performed by modeling method and parallel vertical section method that were generated from 3D models. A comparison of the outcomes of the budget was performed and conclusions were drawn on the reliability of the applied methods
