Abstract

Abstract

En 中文
• Weakening coefficient and UCS–inclination regression quantify inclination-dependent strength degradation. • SEM-based descriptors clarify how pore–crack networks and hydrate bonding control interfacial coalescence. • FLAC3D stope-scale models show inclined interfaces amplify shear concentration and lateral deformation. • FLAC3D stope-scale models show inclined interfaces amplify shear concentration and lateral deformation.
