Identification of the Sedimentary Sources and Origin of Uranium for Zhiluo Formation of the Tarangaole U Deposit, Northeastern Ordos Basin

Minerals
The large-sized Tarangaole uranium deposit and its neighboring Daying and Nalinggou deposits, located in the northeastern margin of the Ordos Basin, constitutes a major uranium resource base in northern China. In order to further clarify the sedimentary material source, uranium source and regional sediment–tectonic setting of the uranium-fed clastic ...

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 ...

UFLI-Based Uranium Anomaly Layer Delineation and 3D Orebody Reconstruction of the Daying Uranium Deposit Within the Northern Ordos Basin, China

Geosciences
Sandstone uranium deposits exhibit stratabound mineralization and strong vertical heterogeneity in geological space, which complicates the identification of uranium anomaly layers and their integration into deposit-scale 3D models using borehole datasets.
