Numerical modeling is a crucial tool for improving mine design and safety by simulating the complex geotechnical conditions and the behavior of rock and soil masses (AZoMining, 2024).
It allows engineers to predict the stability of tunnels, excavations, and slopes, aiding in the design of optimal mine layouts and support systems (Pejuni).
By simulating stress distributions and deformations around mining excavations, numerical models help identify potential failure mechanisms and high-stress concentrations, enabling the design of safer and more efficient excavation spans and sequences (AZoMining, 2024).
In terms of safety, numerical modeling plays a vital role in hazard assessment by realistically simulating stress paths, rock mass yielding, and post-peak responses, which helps in predicting and preventing hazards like rock bursts and pillar failures.
It enables the evaluation of support design under various loading scenarios, ensuring appropriate sizing and optimization of rock bolts, shotcrete lining, and cable bolts (AZoMining, 2024).
Furthermore, numerical models can assess and manage risks by simulating different mining scenarios and analyzing the potential for ground instability, allowing for the development of effective risk mitigation strategies (Pejuni).
The insights gained from numerical modeling, such as predicting ground behavior and evaluating the effectiveness of support systems, contribute significantly to safer and more sustainable mining operations (ResearchGate, 2016).
