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 ...
