Optunimizer

Total Mine Optimization

GeoMine Optunimizer (Optunimizer) is a total mine optimization tool for economic evaluations of mining complexes. Optunimizer consists of two submodules: Optunimizer.TotalMine (to be released soon) and Optumizer.Transitioner (available now). 

Optunimizer.TotalMine can generate optimal strategies for a mine complex comprising multiple mine sites feeding to a single processing plant.  Such an optimal strategy consists of a cut-off grade policy and a combined LOM production schedule for the mining complex. Optunimizer.TotalMine depends on some or all of the following GeoMine modules: FlowPit, Stopemizer/Cavemizer, and OptimCut.

Optumizer.Transitioner is capable of determining the optimal transition zone for near-surface deposits with considerable vertical extent that has the potential to be mined by a combined method of open-pit and underground mining.  As the open-pit reserve in such a mine gets depleted, it is essential to determine the best cut-over point from open-pit to underground mining. Optumizer.Transitioner depends on two GeoMine modules: FlowPit, Stopemizer or  Cavemizer.

Optunimizer has the following key capabilities:

Optunimizer Key Benefits

  • Guaranteed Optimality: The generated transition zone is guaranteed to maximize the total profit of the entire mine.
  • Productivity: Automatically determines the optimum transition zone between open-pit and underground mining, eliminating the need for trial-and-error and thus significantly improving productivity.
  • Flexibility: Incorporates each mine's specific input and constraints easily with GeoMine's Formula Editor.

Optunimizer Feature List

Foundation Feature List - included

Transparent interface to FlowPit and Stopemize/Cavemizer so that the output of these modules (nested pit designs and stope/cave designs) can be directly used as input to Optunimizer.

Transparent interface to iScheduler-OP and iScheduler-UG so that the output of Optunimizer can be directly used as input to these two modules to generate medium or short-term schedules.

Automatic and manual dependency generation between nested pits and/or stopes in multiple mine sites.

Generates N-best cut-off grade and production rate strategies (LOM schedules); Each maximizes the NPV of the entire mining complex with optional stockpiles.

Defines the optimum transition zone from open-pit to underground mining from the generated nested pits and stope or caving design.

Enables users to decide how they want to calculate the dollar values of a block when mined as part of an open-pit and/or as part of an underground mine.

Generates tabulated yearly schedules, graphs and plots.
