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...
