Using OPAL laser scanners deployed around cluster of stockpiles at mine site, 3DRi™ Stockpile software automatically monitors stockpile levels and reports volumes. Dust-penetrating OPAL scanners are specifically designed for harsh, dusty environments and can be deployed without any special, air-conditioned or heated enclosures. Through 3DRi web interface, users can remotely schedule scanning events, define individual stockpiles in cluster, and customize automatic reporting.
