ABSTRACT
Purpose. To substantiate the effectiveness of digital photogrammetric surveying for determining the areas and volumes of finished product stockpiles and constructing three-dimensional models of mining objects.
Methodology. The study is based on the use of UAV aerial photography, digital image processing, and the generation of a dense point cloud with subsequent construction of a digital surface model and determination of volumetric and spatial parameters.
Results. It was found that the photogrammetric approach ensures the required measurement accuracy within a short time depending on the camera resolution and the number of acquired images. The optimal survey parameters were determined: flight height 30–50 m, number of images 25–50, resolution 12–18 MP. The obtained results showed a deviation of 0.09–0.25 % from reference tacheometric measurements, which confirms the effectiveness of the method. Additionally, variations in image processing parameters affect the accuracy of digital model construction and volume calculation.
Scientific novelty. It was established that the accuracy of determining the volumes of crushed stone stockpiles depends on the parameters of aerial photogrammetric surveying, in particular UAV flight height, camera resolution, and the number of images. The optimal survey parameters (flight height 30–50 m, number of images 25–50, resolution 12–18 MP) were substantiated, ensuring minimal deviation of the results (0.09–0.25 %) from reference tacheometric measurements. The influence of photogrammetric data processing parameters on the accuracy of three-dimensional model construction and volume calculation was determined.
Practical significance. The practical significance lies in the possibility of integrating photogrammetric technologies into the mine surveying support system of mining enterprises for operational monitoring of finished product stockpiles and digital modeling of mining objects. The proposed approach makes it possible to reduce the duration of field and office work, minimize the influence of the human factor, and increase the efficiency of stockpile volume determination.
