Analysis of the Evolution Law of Mining‐Induced Water Flowing Fracture of Composite Hard Roof in the Border Mining Area of Inner Mongolia and Shaanxi

Energy Science &Engineering, Volume 13, Issue 4, Page 1720-1731, April 2025.
Multiple research methods were employed to analyze the fracture characteristics and migration patterns of the two thick layers of pressurized water‐bearing sandstone commonly found in the mining area bordering Inner Mongolia and Shaanxi, further elucidating the evolution characteristics of mining‐induced water‐conducting fissures.

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.

Groundwater conditions and hydrogeochemistry of the shallow Benin Formation aquifer in the vicinity of Abraka, Nigeria

, 2014
Shallow borehole and dug well data are used in describing groundwater conditions in the vicinity of Abraka in the Nigerian coastal plain. Drill cuttings from ten boreholes show that the Abraka area is underlain by reddish brown unconsolidated sands ...

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 ...

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 ...
