Numerical investigation of geomechanical responses of pillar during sequential stope-and-fill operations in squeezing rock
R Wang, Shichen Song, L Liu, Jie Yang et autres
Mechanical performance of the intervening pillar critically influences extraction efficiency and operational safety in multiple stope-and-fill mining operations. However, the time-dependent interactions between backfill and creeping rocks and the resulting impact on pillar behavior remain poorly quantified, posing significant challenges in scheduling …
