3D modeling of terrain and spatial visualization of underground facilities at the 'Crveni Breg' mine

This paper presents the process of making the 3D model of terrain, digital elevation model and orthophoto at the location of the "Crveni Breg" mine. The necessary photos were taken with a 20-megapixel digital camera attached on the DJI Phantom 4 Pro photography UAV. AgiSoft PhotoScan was used to create the 3D model of terrain. A spatial visualization of mining facilities on the second horizon of the “Crveni Breg” mine was carried out with the assistance of this 3D model of the underground facilities designed in the Autodesk Civil 3D software. Two 3D models were connected to obtain complete spatial visualization of the area. The aim of this paper is to present a general overview of the possibilities that emerge by combining digital aerial photogrammetry and 3D models of underground mines, primarily in the context of protecting infrastructure, and other objects from the impact of underground mining operations as well as serving as a quick, simple, easy and relatively reliable track for potential subsidence.
