January 12, 2023 – Ottawa. ThreeDify is thrilled to announce the general availability of GeoMine OreController, an Open-Pit grade controller designed to create and sequence fine-grained dig-units based on 3D blast movement modeling in order to minimize dilution and ore losses for bench mining.
Traditional grade control practice usually entails determining the dig limits for bench cuts of an open-pit bench against an in-situ block model. This fails to model the reality: after a blast is fired, blocks on the bench will break, throw and mix with their neighboring blocks, invalidating the predefined dig limits for all, but trivial, cases. The dilution and ore losses have also been hard to quantify and are usually a guesstimate by experience or determined after the fact.
A better approach emerging in recent years has been to take into account the impact of 3D movements of the rock being blasted. OreController is designed specifically for this purpose. With OreController, the user only needs to specify an in-situ block model and a pair of topographical bench surfaces before and after blast. A post-blast model will be generated automatically and it can be used to create fine-grained shovel-truck dig units which can then be scheduled by iScheduler-OP against the blast model.
