Mining and coal operations often manage large stockpiles, silos, ore storage areas, and processing materials. Coal inventory solutions need to account for irregular stockpile shapes and constant material movement. RETTAR combines 3D scanning technologies with inventory software to create digital representations of stockpiles and storage areas. Automated 3D inventory mapping can help operators understand how much material is present and where it is distributed across the storage area. For silo applications, 3D radar can provide information about material level and volume, while other measurement technologies can address specific process requirements. The resulting data can support stockpile inventory management, operational planning, and material tracking. In mining environments, having an updated view of physical inventory can also help teams compare changes between measurement periods and make decisions based on current storage conditions rather than relying solely on manual surveys.
