Do you have a near-surface deposit with considerable vertical extent that has the potential to be mined by a combined method of open-pit and underground mining? As the reserve in an open-pit gets depleted, many medium to large open-pit mines face challenges in determining the best cut-over point from open-pit to underground mining.
GeoMine Optunimizer (Optunimizer) is an Open-pit to Underground Transition Optimizer. Optunimizer allows a mine planner to determine the optimal transition zone from open-pit to underground mining with the objective of maximizing total profit of the entire mine. Optunimizer is built on top of three ThreeDify optimizers: FlowPit for pit optimization, Stopemizer for stope optimization, and Cavemizer for caving optimization. As a result, the transition plan created by Optunimizer is optimal for both open-pit and underground mining - there is no longer a need for a trial and error design process.
Optunimizer not only determines the location of the best transition zone, but also provides the planner an option to use a crown pillar within the transition zone. Furthermore, Optunimizer is agnostic to underground mining methods: it can be applied to stoping and caving methods (including sublevel caving and block caving). Combined with iScheduler for development and production scheduling, Optunimizer has the following key capabilities:
