Investigation of the Mechanical Properties and Strain-Displacement Field Evolution of the Rock-like Backfill Composite Structure Under Biaxial Loading

In the subsequent backfilling mining method, the composite structure formed by the ore pillar and the backfill is the key element in ensuring the stability of the working face. Its mechanical behaviour directly affects mining safety and ore recovery rates. In order to elucidate the mechanical response and failure mecha...

Dynamic Mechanical Properties and Damage Constitutive Model of Layered Cemented Backfill Under Blasting Disturbance

In this study, we explore the static and dynamic mechanical responses of layered cemented backfill subjected to blasting loads. Variable-rate uniaxial compression tests and Split Hopkinson Pressure Bar (SHPB) numerical simulations were performed on specimens with three different interlayer cement-to-tailings ratios. Al...

Mechanical properties and damage constitutive model of tuff under stress–seepage coupling during low-temperature curing

Given the challenging conditions of high-alpine and high-altitude metal mining, complex factors affecting rock mass quality, and the intricate mechanisms of slope instability, this study focuses on the tuff from the high-alpine and high-altitude region of China. The deformation, strength, and failure characteristics of...
