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.

Hydrogeochemical processes of groundwater system and its mining-motivated effect in mining areas of Western China

Meitan xuebao
The exploitation of coal resources will destroy the aquifer structure, disturb the groundwater system and produce a new water cycle model. As the focus of coal supply and production, the western mining area is short of water resources and fragile in ...

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.

Analysis of the Influence of Boundary Permeability Characteristics Under Fluid–Solid Coupling on Surface Subsidence in Deep Near‐Horizontal Coal Seam Mining

Shock and Vibration, Volume 2024, Issue 1, 2024.
The fluid–solid coupling effect is an important factor which cannot be ignored to study the surface subsidence of deep coal seam mining in the area with abundant underground water. To study the influence of boundary permeability characteristics on surface subsidence in deep near‐horizontal coal seam mining under the effect of fluid–solid coupling, the ...
