Water‐Inrush Risk Assessment of Roof‐Confined Aquifer Strata Based on FAHP–RF Model in the Arid–Semiarid Ecotone: A Case Study of Zhuanlongwan Coal Mine

Geofluids, Volume 2026, Issue 1, 2026.
Water inrush poses a serious threat to the safety and sustainability of coal mining operations, particularly in arid–semiarid regions where confined aquifers overlie coal seams. Therefore, an accurate assessment of roof water inrush risk is essential to prevent water hazards on the roof.

Study on Mine Earthquake Prediction Based on Numerical Simulation of Rock Fracture Evolution

Energy Science &Engineering, Volume 13, Issue 4, Page 2082-2097, April 2025.
This study analyzes the geomechanical behavior and fracture evolution of overlying strata to prevent rock bursts and identify mine earthquake sources. By establishing a refined stope model and applying the “O–X” fracture mechanics model, combined with microseismic monitoring data, this study reveals the spatiotemporal evolution laws of strata migration
