Stochastic open pit optimization
Orebody geological uncertainty has a significant impact on the real value of a mining project. A stochastic mine optimization approach was used for designing open pit mines based on geological uncertainty in association with stochastically simulated geological models and traditional optimization. The stochastic approach allowed to develop open pit mine designs that capture maximum upside potential whilst minimizing geological risk.

During the project, several challenges were encountered while working on the simulated orebody models using sGems software in the generation phase. The team had to overcome technical difficulties and ensure the accuracy and reliability of the orebody models before proceeding further. However, once the simulated orebody models were validated, the process of importing them into the stochastic optimizer software and conducting stochastic mine scheduling became quite straightforward.
Significant effort was placed on guiding the stochastic optimizer to develop feasible life-of-mine production sequences. This involved careful analysis of the simulated orebody models' risk profiles and thorough visualization of mine scheduling. By doing so, the team was able to gain a deeper understanding of how geological risk is considered and accounted for in the mining process.
Through this comprehensive analysis and visualization, the project team could identify potential bottlenecks, optimize production sequences, and proactively address any geological risks that could impact the mine's overall efficiency and profitability. This approach allowed for better decision-making and strategic planning, ensuring that the most effective and efficient mining operations were implemented.
Overall, the successful integration of the simulated orebody models, stochastic optimizer software, and thorough risk analysis greatly enhanced the project's outcomes. It provided valuable insights into the complex geological factors that influence mining operations and enabled the team to make informed decisions for the mine's long-term success.
Integrating geological uncertainty into life-of-mine pit optimization has proven to be highly beneficial in the mining industry. By incorporating this uncertainty into the planning process, mine operators are able to achieve higher values in the mine schedule production planning. This means that they can optimize the extraction process to maximize profits and overall productivity.
Additionally, considering geological uncertainty also helps to mitigate the risks associated with mining operations. By taking into account the various uncertainties and potential variations in the geological conditions, mine operators can develop strategies to minimize the impact of any unforeseen challenges. This ultimately leads to a reduction in geological risk over the life-of-mine, safeguarding the financial stability and longevity of the operation.
The effectiveness of integrating geological uncertainty into life-of-mine pit optimization has been demonstrated in a pre-study. This study compared the results of using a stochastic optimization approach with the traditional conventional scheduling methods. The findings confirmed that the stochastic optimization approach yielded a higher value life-of-mine plan.
Overall, the integration of geological uncertainty into life-of-mine pit optimization offers significant advantages for mining operations. It allows for better production planning, improved financial outcomes, reduced geological risk, and ultimately, a more sustainable and efficient mining operation. The results of the pre-study provide concrete evidence of the benefits and serve as a basis for adopting this approach in future mining projects.
