The Volume tool also measures the area of the drawing. Select the Volume tool from the Measure menu at the top of the screen.The best fit base plane is the default plane in Site Scan, and is the most robust of the three it automatically determines the most appropriate fit for the selected area.The highest point base plane works from the highest point in the selected area, and is great in cases where the area is to be filled, such as a trench or hole.This is best suited for stockpiles on a flat surface-or with walls or other stockpiles nearby-that is to be cut. The lowest point base plane finds the lowest elevation within the selected area, and creates the base plane from that point.There are three base planes available that account for the underlying terrain: lowest point, highest point, and best fit. Site Scan Manager's Volume tool is designed to estimate the volume of stockpiles, trenches, and other voids or volumes. For example, flatter stockpiles will benefit more from a high GSD than taller stockpiles.Instructions provided describe how to measure volumes using the Volume tool in Site Scan Manager. Vertically, they lower the uncertainty in Z values, which is proportional to the resolution. ![]() Horizontally, high-resolution photogrammetric results create more precise stockpile models, and thus better volume measurement accuracy than ones interpolated from certain measured points. in an open pit to estimate stockpile volumes from a Mine. A photogrammetric survey with a fine ground sampling distance (GSD, which indicates the actual distance each pixel represents) is able to better describe irregular stockpiles in detail. When it comes to stockpile volume measurements, stockpiles do not conform to a perfect shape. Why use photogrammetry for stockpile volume measurements? High-resolution images give you more details of the mapped stockpiles These top mining companies claim that by applying the photogrammetry workflow with Pix4Dmapper, they can achieve measurement accuracies of around 2-5% for their stockpile volumes. Of the biggest 40 mining companies announced in PWC’s mining report, nearly half of them use Pix4Dmapper photogrammetry software for stockpile measurement and volume comparison as part of their mining workflow.Ĭalculating and managing stockpile inventory, that is, finding a solution for accurate volume measurement and easy inventory management, is one of the biggest challenges in the mining industry. Various technologies have been used to aid in stockpile volume estimation. Large volumes of waste as well as ore is stripped in the process. In surface mining operations, overburdens need to be stripped in other to reach the ore. This is especially true when things go a bit wrong. Mining operations involve the extraction of minerals of economic value from the earth. These screenshots show the 2D (above) and 3D (below) visualisation of the stockpile. ![]() The measure tool can be used in any window where project data is displayed. Then a line between the two will be displayed with a label showing the distance. Diameter known Diameter (D) ft Angle of Repose (A) deg Height (H) ft Volume cubic ft Bulk Density lbs/ft3. Whilst keeping the M key pressed, move the mouse to the next point. To use enter the required data in the highlighted cells Conical Stockpile Capacity 1. The actual tonnage is calculated based on the bulk density of the material. Speed and accuracy: that's the reason why most of the largest mining companies use drones and photogrammetry software in their workflow. Hiring a licensed surveying company to measure and calculate stockpile volumes pays off. This form is for calculating the volume contained in a conical stockpile.
