The most common question considering using drones for stockpile volume determination is the accuracy of measurements and calculations. As an added important benefit, site working operations can continue uninterrupted. The more points that are captured, the more accurate a surface model will be and a drone can capture more points than a surveyor using traditional methods, in a fraction of the time. An alternative is using unmanned aerial vehicles (UAV), known as drone, to calculate stockpile volumes. The surveyor is also exposed to various dangerous conditions (walking near heavy equipment, climbing up unstable stockpile surfaces, etc.). Measuring all the stockpiles in a large stockyard using this method is time consuming and expensive. The models are compared against a baseline surface to calculate volume changes. Once these points have been captured, the surveyor generate surface models. The points are selected around the base of the stockpile, on top of the stockpile and along the break lines. Using traditional ground-based surveying methods to calculate the volume of aggregate stockpiles means a surveyor team must take their equipment on site and capture the coordinates and elevation of multiple points. Most of the aggregates produced are from natural resources (sand, gravel, crushed rock) in surface quarries. The Romeoville plant has the capability to produce 1800 tons per hour of crushed limestone in various sizes used in highway construction, building products and other manufacturing processes.In the mining industry the aggregates sector has an important size in terms of production quantity. With HDG all their requirements were accomplished for durability, sustainability, and environmentally friendliness. They also wanted an environmentally friendly coating. The customer had required a coating that would provide a long usable life with minimal maintenance. ![]() ![]() The abrasion resistance of the HDG coating will mean little or no maintenance for decades. The system is subject to constant moisture, being hit by limestone material, and nicked by small grains of limestone. This system processes limestone in a very harsh, wet environment. In an industrial marine development, the Romeoville plant blends perfectly with the surrounding environment making it a community friendly operation providing employment to local people. The galvanizer provided uniformity for all ladders, stairs and platforms ensuring solid connections that will remain corrosion free. The screening plant is in constant state of vibration, requiring precision for all bolt together assemblies. The cathodic protection of the zinc coating makes a strong visual statement of durability and superior protection, and more than 200 tons of screen tower, splitter feed chutes, gathering conveyors, stockpile conveyors, and walkway platforms were galvanized. In turn the manufacturer was able to deliver the finished product on time. The galvanizer offered a customized turnaround time that allowed extra time to install auxiliary motors, liners and belts. Since HDG steel is the most recycled product in the world and this plant will probably outlast the quarry, it is good to know that this project site can be reclaimed and be part of the sustainable development of the area. Additionally, the manufacturer had used HDG on previous projects that required superior corrosion protection, made the choice to galvanize this structure with the greatest confidence. Hands down, HDG was the most cost effective solution. While the initial cost was competitive with paint, the life cycle cost was miniscule in comparison to what the maintenance would be on a painted structure in this harsh environment. The manufacturer was impressed by the AGA life cycle cost calculator, which reveals the savings of hot-dip galvanized steel over the life of a project.
