Accurate estimation of stockpile volumes and efficient inventory management play a critical role in ensuring efficiency and profitability in the mining industry. Businesses across the globe are using volumetric estimation processes to determine the volume of bulk commodities kept in stockpiles, such as ores, minerals, and other aggregates. In this blog, we’ll explain what stockpile volumetric estimation is, how it works, and why drone technology is needed to achieve accurate estimation.
Understanding Stockpile Volumetric Estimation
Stockpile volumetric estimation is the process of determining the size, volume or weight of material in a stockpile by creating accurate 3D models. This process provides accurate insights into the quantity of materials stored, enabling effective inventory management, cost optimization and better operational planning.
Traditional Stockpile Measurement Methods
Some of the traditional stockpile measurement methods include manual surveys, terrestrial laser scanning, and manned aircraft surveys, all with varied accuracy and use cases. Manual surveys are labour-intensive, subject to human error, and require workers to navigate through uneven and hazardous terrain. Terrestrial laser scanning, on the other hand, is slightly more accurate but requires high setup costs and is time-consuming. Similarly, manned aircraft surveys are expensive, not environmentally friendly, and less accurate than today’s technology alternatives, such as drones.
