Optimization of bauxite surface mine L-1 using the moving slopes method : master’s thesis

Abstract

U radu je obrađena optimizacija površinskog kopa boksita „Skakavac“. Samo ležište se nalazi u BiH, u općini Jajce u županiji Središnja Bosna. Topografske karte su korištene kao podloga za izradu situacijske karte ležišta. Geološkom prospekcijom, istražnim radovima i bušotinama definirano je nalazište boksita. Izrađen je 3D model terena i 3D model rudnog tijela koristeći program Bentley Microstation. Sama obrada dobivenih podataka i njihovo generiranje, triangulacija izvedene su u programu Bently InRoads. Opisane su suvremene metode projektiranja površinskih kopova, s naglaskom na primjenu metode pomičnih kosina. Proračun rezervi boksita izrađen je metodom modeliranja. Izrađeno je više modela površinskog kopa i utvrđena je optimalna kontura kopa.This paper deals with optimization of bauxite surface "Skakavac". The bauxite reservoir is located in BiH, in the Jajce municipality in Central Bosnia. Topographic maps were used as a basis for creating a situation map of the deposit. Geological screening, exploration works and wells have been defined as bauxite sites. A 3D model of terrain and a 3D model of the mining body was developed using the Bentley Microstation program. The same processing of the data obtained and their generation and triangulation were performed in Bently InRoads. Modern design methods of surface mines are described, with emphasis on the application of the moving slope method. Budget of bauxite reserves were made by the modeling method. Several surface finishing models were developed and the optimal contour of the mine was determined
