MODERN METHODS FOR THE CALCULATION OF STOCKS VOLUMES EXISTING IN SURFACE MINING EXPLOITATIONS PUBLISHEDSilviu DOROBANTU, Larissa FILIP, Nicolae DIMA None email@example.com
The work presented in this paper consists in taking photogrammetric images with the help of drones, realizing their mosaic and georeferencing the orthophotomap resulting in the national stereographic projection system 1970. The calculating methods of volumes of materials situated inside the surface mining exploitations, based on satellite measurements and programs specific calculations, are also presented. For these measurements, a Leica GNSS system, as well as a specialized software were used. These data were combined with the cloud of points resulting from the photogrammetric flight, thus obtaining a high accuracy on the calculated volumes. The purpose of this paper is to present a modern alternative to classical topography. This is much faster and more accurate in both accessible places and areas with unsafe conditions for the human factor. At the same time, this method offers the possibility of collecting much larger number of field details, compared to an ordinary measurer.
