Stockpile Survey
What is The Stockpile Survey and Volumetric Calculation
Stockpile survey are widely used in various sectors, including mining, cement plants, construction, and logistics, to facilitate efficient resource management. Their primary purpose is inventory control, where organizations need to accurately measure the amount of clinker, coal, iron ore, aggregates, or other bulk materials held in stockpiles. Additionally, these surveys assist in financial reporting by providing reliable data for valuation, audit, and taxation.
Understanding accurate stock levels improves operational planning, allowing managers to effectively schedule production, transportation, and sales. Safety is another important aspect, as surveys assess slope angles and pile stability to prevent collapse. Environmental compliance is supported by monitoring the footprint of stockpiled materials and ensuring they remain within permitted limits. By providing transparent and scientifically measured volumes, stockpiling surveys help reduce disputes between suppliers, contractors, and buyers. Overall, they are the cornerstone of modern resource management, balancing productivity, safety, and accountability in the bulk materials industry.
Modern reservoir surveys use the latest equipment and digital technologies to ensure high levels of accuracy and efficiency. Total stations are commonly used, which combine electronic distance measurements with angular calculations to obtain accurate 3D coordinates of reservoir surfaces. GPS/GNSS systems, especially RTK and PPK, provide centimeter-level accuracy, making them particularly suitable for large industrial sites. The innovation of 3D laser scanning has significantly transformed reservoir surveys by collecting 3D point cloud data and processing it into 3D models. LiDAR scanners offer even greater accuracy, effectively generating composite point clouds that penetrate all types raw materials and complex terrain.

National Line Survey Calculating Stockpile Volumes Accurate and Fast
3D laser scanning technology, GPS surveying, and drone surveying techniques offer quick and economical solutions for calculating storage volumes. This applies to storage located outdoors, inside silos, or in warehouse storage facilities. High-precision 3D laser scanners, when paired with GNSS and IMU (inertial measurement unit) equipment, can be mounted on vehicles and navigated around mine sites and stockpiles. This capability supports 3D modeling – or building information modeling – which results in accurate calculations of the volume of raw materials, crushed and ground materials, clinker, iron ore, limestone, cement plant raw materials, minerals, waste, or unprocessed ore stockpiles.
Regardless of the type of material in a stockpile survey, whether it consists of coal, asphalt, sand, clinker, iron ore, limestone, or others, we can measure the material with accuracy. The implementation of remote sensing and 3D laser scanning survey methods greatly increases on-site safety when measuring stockpile volume and significantly reduces the time required to obtain results.
