3D MODELING OF WASTE DUMPS IN ORDER TO ECOLOGY OF MINING AREAS

Abstract

The use of geomatics technologies in the mining engineering field, presents a modern approach for the conservation and greening of the areas affected by open or underground pits. The purpose of this research is to accomplish a threedimensional model of the active waste dump of the Uricani Mine. Based on the three-dimensional model, the volumes of deposited waste ore could be determined and it could be created an overview map of the area that will be subjected to greening: landscaping and revegetation. The greening works involve the landscaping, geometry, weeding and afforestation of the landfill area that has an area of 3.68 ha. In this context, the use of modern photogrammetric (UAV) and satellite (GNSS) measurement technologies, have been the fundamental basis for data acquisition from the field with a high precision, in order to achieve the three-dimensional model of the studied area. The combination of the satellite methods with the photogrammetric ones has led to the creation of an accurate 3D model that will be fundamental in the process of greening the waste dump.
