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 two ThreeDify's mature optimizers: FlowPit for pit optimization and Stopemizer for stope and 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 all stoping methods as well as all caving methods (including longwall, sublevel caving and block caving). Combined with iScheduler for development and production scheduling, Optunimizer has the following key capabilities:
