Special Issue Information

Dear Colleagues,

Computational mechanics and digital applications are constantly growing fields that impact science and industry in all engineering fields, including the mineral resources sector. In the modern era, the automation, electrification, and digitalisation of the minerals industry; the rising implementation of artificial intelligence and machine learning; and the challenges of big data management deem the use of computational mechanics and digital tools more important than ever.

Solving mining, mineral processing, geotechnical, and rock mechanics problems using numerical and analytical methods and computational power is essential for improving the mineral industry's efficiency, safety, and sustainability.

The areas of application are numerous. Computational mechanics aid in the simulation and modelling of geological structures; optimising mine layouts, extraction sequences, and scheduling; and helping researchers and engineers understand the microstructure of materials before processing or using them in applications.

Furthermore, digital simulations enable the assessment of the stability of mine structures, such as slopes, tunnels, and waste dumps. This information is vital for ensuring the safety of mining operations and preventing accidents. Digital applications enable the real-time monitoring of environmental parameters (for instance, the volume and stability of waste dumps), allowing mining companies to respond quickly to any issues and minimise their impact on ecosystems.

The data gathered can also be used to optimise mine closure plans, restoration, and post-mining land use. Furthermore, they provide realistic training simulations for miners, which improves their skills and preparedness for various scenarios and ultimately enhances safety.

Accordingly, this Special Issue investigates the importance and efficiency of computational mechanics and digital applications in several disciplines of the mineral resources sector, like mining, post-mining, mineral processing, geotechnical engineering, and rock mechanics. The focus is on introducing innovative developments, addressing advantages and bottlenecks, and demonstrating tangible outcomes through case studies worldwide.

The expected outcome of this Special Issue is to demonstrate how computational power has evolved in the mineral resources sector, how applications are optimising operations throughout a mine’s life cycle, and how this impacts the education and training of future engineers.

Please do forward this call for papers to your team members and colleagues who may also be interested in the topic.

Accurate rock mass quality classification is crucial for the design and construction of underground projects. Traditional methods often rely on expert experience, introducing subjectivity, and struggle with complex geological conditions. Machine learning algorithms have improved this issue, but obtaining complete rock mass quality datasets is often difficult due to high cost and complex procedures. This study proposed a hybrid XGBoost model for predicting rock mass quality using incomplete datasets. The zebra optimization algorithm (ZOA) and Bayesian optimization (BO) were used to optimize the hyperparameters of the model. Data from various regions and types of underground engineering projects were utilized. Adaptive synthetic (ADASYN) oversampling addressed class imbalance. The model was evaluated using metrics including accuracy, Kappa, precision, recall, and F1-score. The ZOA-XGBoost model achieved an accuracy of 0.923 on the test set, demonstrating the best overall performance. Feature importance analysis and individual conditional expectation (ICE) plots highlighted the roles of RQD and UCS in predicting rock mass quality. The model’s robustness with incomplete data was verified by comparing its performance with other machine learning models on a dataset with missing values. The ZOA-XGBoost model outperformed other models, proving its reliability and effectiveness. This study provides an efficient and objective method for rock mass quality classification, offering significant value for engineering applications. Full article
