Grade Control Optimizer with 3D Blast Movement Modeling & Sequencing

GeoMine OreController (OreController), is an Open-Pit grade control optimizer designed to create and sequence fine-grained truck-by-truck dig-units (TBT units) based on 3D blast movement modeling that aims to minimize dilution and ore losses for bench mining.

Traditional grade control practice usually entails determining the dig limits for the 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 the 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.

OreController Key Benefits

  • More Accurate：Controls dilution and ore losses with 3D blast movement modeling & automated dig unit generation and sequencing.
  • Performance：Models large bench cuts with fine-grained blast model within minutes
  • Easy-to-Use：Interactive WYSIWYG 3D workflow makes it easy to iterate over your modeling scenarios.
  • Flexible: Includes a powerful Visual Formula Editor for customization, plus all common surface, solid and block model manipulation tools in the Foundation module of GeoMine.
  • Supportive：Tailored training and professional services to customize our software to suit your deposit.

OreController Feature List

Foundation Feature List - included

Generates 3D blast models from an in-situ block model and a pair of topographical bench surfaces before and after blast.

Automatically generates and sequences thousands of fine-grained TBT units from the blast model. These TBT units closely follow the ore and waste delineation of the generated 3D blast model.

Option to interactively edit sequences of TBT units;

Output the statistics of the modeled dilution and ore losses.

Creates TBT activities against the blast model for scheduling with iScheduler-OP (requires an iScheduler-OP license)
