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

Origin of Water and Hydrochemical Components of Lakes: Example From the Mu Us Desert, Northwest China

Water Resources Research, Volume 61, Issue 2, February 2025.
Abstract Desert lakes are sparsely distributed in arid/semi‐arid regions of the world and are crucial to desert hydro‐ecosystem. However, the sources of water and dissolved components in desert lakes, especially the inputs from anthropogenic activities, remain to be fully understood.

Surface Subsidence Prediction Model in Deep Composite Lithologic Gangue Backfill Mining of Under the Coupling Effect of High Ground Stress and Water Environment

Advances in Civil Engineering, Volume 2025, Issue 1, 2025.
Under the coupling action of high ground stress and water environment, the physical and mechanical properties of backfill will change to some extent, and then secondary compression will occur. In this study, a prediction model of surface subsidence in deep filling mining was established through the combination of physical tests and theoretical analysis.

Study on Overlying Rock Movement and Surface Highway Deformation Under Deep Mining–Induced Fluid–Solid Coupling Effects

Shock and Vibration, Volume 2025, Issue 1, 2025.
Current research on deep mining–induced overburden movement and highway deformation has neglected the amplification effect of fluid seepage‐rock mass deformation coupling interactions on differential settlement, while predominantly focusing on highway alignments parallel or orthogonal to underlying working faces.
