The importance and purpose of the study are to highlight the presence of geomatics technology in mining engineering works. Based on the research and studies carried out to obtain the extension of the mining license for the mineral aggregates and existing sand and gravel deposits in the Cicir Halta area, Arad county, the UAV technology in combination with the classic measurement technology, respectively GNSS, data acquisition and processing had. the time factor by the requirements imposed by the entity issuing the notice. The results obtained with the help of UAV technology are orthophoto planes, digital elevation models, or 3D models, which can be easily processed with dedicated software. For example, after the orthophoto maps was imported into AutoCAD, the perimeters of the studied area could be easily vectorized in detail. Once the vectorization of the aggregate quarry was completed, the final plan was obtained, following which the necessary documentation was drawn up to obtain the permit for the exploitation of the sand and gravel resources in the studied perimeter. The necessary documentation has been drawn up regarding the ability to carry out mineral resources exploitation works: useful rocks, through topography and geology works. UAV technology in combination with GNSS technology is the evolutionary step in obtaining precision measurements with a working speed.
