3D MODELING OF THE ROSIA POIENI ORE DEPOSIT USING THE LEAPFROG GEO PROGRAM
Abstract
As part of the GoldenEye project with European co-financing type H2020, the Academic Leapfrog Geo licensed program was purchased, with which a 3D modeling of the deposit body was made based on open source data, geological maps of the Romanian Geological Institute, non- secret data of CUPRUMIN company and drone flights. The ore has not been modeled in 3D up to now, this work presents for the first time the first consolidated modeling that highlights the size of the ore deposit body. These modelings will allow the taking of technical decisions regarding: the mode of exploitation ( open-pit /underground, redefining the depth of the exploitation limit, the location and development of waste dumps, the geometry of the open pit, the location of underground mining works and preparation works for underground exploitation, data from structural geology). The 1:1 scale geometry of the open pit was traced through topographical measurements from the ground, drone and satellite surveys using Copernicus images. These data were correlated to check the information flow and the efficiency of the internal reporting of the project team in close collaboration with the CUPRUMIN beneficiary team. Three large monitoring campaigns were carried out in the period August 2021-May 2022-September 2022, on the current geometric model of the open pit, the drillings of thousands of meters were positioned with the initial coordinates and lengths, the main faults, the state of stability/instability of the slopes, the identification of four major categories of rock types.
