Geomechanical Modeling: Geological models provide the foundation for geomechanical modeling, which assesses the stability of pit slopes under various geological and mining conditions.
Risk Mitigation: The integration of geological models aids in identifying potential slope stability risks, enabling proactive measures to mitigate these risks and enhance overall safety.
7. Geological Controls on Mining Processes:
Blast Design: Understanding the geological structures within the pit influences blast design, optimising fragmentation and facilitating efficient material handling.
Haul Road Planning: Geological models contribute to the planning of haul roads by considering the geological characteristics that may impact road stability and maintenance.
8. Real-Time Monitoring and Updates:
Integration with Monitoring Systems: Geological models seamlessly integrate with real-time monitoring systems, allowing for continuous updates on pit conditions and geological features.
Data-Driven Decision-Making: Real-time geological information informs on-the-fly decision-making, enabling timely adjustments to mining plans based on evolving geological insights.
9. Environmental Impact Assessments:
Water Flow Modeling: Geological models aid in water flow modeling, supporting environmental impact assessments by predicting how geological structures may influence water movement within and around the pit.
Mitigation Strategies: Understanding the geological controls on water flow helps develop effective strategies for water management and environmental protection.
10. Continuous Improvement and Learning:
Data Feedback Loop: The integration of geological models creates a data feedback loop, allowing geologists and mining engineers to continuously refine models based on new geological data and mapping observations.
Improved Predictive Modeling: Continuous learning and refinement contribute to improved predictive modeling, enhancing the accuracy of future geological assessments and pit structural mapping.
