Land Degradation Pathways of Open‐Pit and Underground Mining in Karst Regions: A Spatial Indicator Assessment

ABSTRACT Mining in the karst regions of southwest China threatens ecosystem stability and accelerates land degradation. Regional evaluation rarely distinguishes between degradation pathways in open‐pit and underground operations, due to spatial heterogeneity and geomorphological...

Water and salt migration model of solidified sulfate-contaminated soil by full solid waste cementitious materials

The limitations of the research on the water-salt migration of sulfate-stained soil using solid waste as the sole binding material, such as the difficulty in characterizing the hydration reaction products over time, were addressed in this study. The research focused on different...

Simulation study on the mechanical evolution law of double-arch tunnel construction without middle drift

The construction method without middle drift can simplify the construction organization process of double-arch tunnels, thereby improving construction efficiency. However, the mechanical evolution of the surrounding rock and support system, as well as the working mechanism of the...
