MINEXCELLENCE 2021: Optimizing Shaft Rehabilitation Through Sensitivity Analysis

Introduction

At MINEXCELLENCE 2021, Luiggi Sassarini presented findings on the critical role of sensitivity analysis in shaft rehabilitation projects. The research focused specifically on a case study from Peru, where sensitivity analysis was applied to optimize the project’s critical path and improve overall efficiency.

The Role of Sensitivity Analysis

Sensitivity analysis serves as a crucial tool in project management, particularly for complex mining operations like shaft rehabilitation. It helps project managers:

• Identify which variables have the most significant impact on project timelines
• Understand how changes in one area affect other project components
• Make data-driven decisions about resource allocation
• Better predict and mitigate potential delays

Case Study Findings

The presentation examined a specific shaft rehabilitation project in Peru, where sensitivity analysis was applied to various project parameters. Key findings included:

• Critical path activities were most sensitive to equipment availability
• Labor resource allocation had a significant impact on timeline variations
• Weather conditions showed minimal effect on overall project duration
• Material delivery schedules required careful monitoring due to their high sensitivity rating

Practical Applications

The research demonstrated that implementing sensitivity analysis in shaft rehabilitation projects can lead to:

• More accurate project scheduling
• Better resource allocation
• Improved risk management
• More reliable cost estimations

Conclusion

The MINEXCELLENCE 2021 presentation highlighted how sensitivity analysis can significantly enhance project management in mining operations. By understanding which variables most affect project outcomes, managers can make better-informed decisions and improve project efficiency.
