A scientometric analysis of 2449 journal articles and a comprehensive review of 336 papers were conducted, discussing and identifying challenges and research gaps in rockburst prediction and prevention and proposing an ontology‐based framework for better decision‐making in underground excavations. Abstract With underground engineering projects becoming

Interpretable tree‐based models integrate microseismic, geological, and mining indicators to predict short‐term rockburst risk. SHAP analysis reveals the dominant role of energy‐related features and clarifies nonlinear factor interactions, enabling transparent and reliable early‐warning in deep coal mines.

Water and Artisanal and Small‐Scale Gold Mining: A Review of the Literature
This paper reviews the relationships between artisanal and small‐scale gold mining (ASGM) and water. We show the variegated impacts ASGM has on water and, thus, socio‐ecological systems and health. We conclude by identifying gaps in the scholarship.

Design of Initial Mining Pressure Relief Scheme for Large‐Size Mining Face: A Case Study
The numerical simulation analysis method is used to compare the actual mining face (315 m) with the designed mining face (200 m). The results show that the large mining height working face has larger abutment pressure peak and stress concentration factor than the general mining height working face.

With the advancement of coal mining technology driving the development of working faces toward increased mining heights and extended lengths, the enlargement of face dimensions has led to expanded overlying strata failure zones and intensified ground pressure manifestations. Consequently, traditional methods for determining hydraulic support resistance

Gas concentration prediction model for fully mechanized coal mining face
In view of problems of gas concentration prediction method based on least squares support vector machine (LS-SVM) such as easy to fall into local optimal solution, low search efficiency and easy to occur premature convergence during parameter optimization process, a gas concentration prediction model based on ACO-LS-SVM was proposed.
