Analysis And Comparison Of Volumetric Calculations For Open-Cast Mines Using Two Different Surveying Techniques: Drone-Based Photogrammetry And Traditional Total Station Method

Abstract

This study presents a comparative analysis of volumetric calculations in open-cast mining using two distinct surveying techniques: drone-based photogrammetry and conventional total station methods. The primary aim is to evaluate the accuracy, efficiency, and practicality of both approaches in estimating stockpile volumes, excavation quantities, and overall site topography within open-pit mining operations. Drone surveys, leveraging advanced photogrammetric techniques, enable rapid data acquisition and the generation of nhigh-resolution 3D models, offering considerable time savings and reducing the potential for human error. Conversely, total station surveys—renowned for their precision and reliability—deliver accurate ground-based point measurements. While more labor-intensive, they remain a preferred method in the mining industry, particularly forn smaller areas where high precision is paramount. This study outlines the advantages and limitations of both techniques, focusing on parameters such as survey duration, cost-effectiveness, data processing requirements, and the accuracy of volume estimations. The findings indicate that drone surveys provide a faster and more efficient alternative, whereas total station surveys excel in confined or detail intensive environments. Ultimately, the study underscores the potential for integrating both methods to optimize volumetric assessments in open-cast mines, combining the strengths of each for more robust and adaptive mine planning.
