| Description | Direct shear tests were carried out with planar interfaces between cemented backfill and rock to obtain cohesion and friction angle. Triaxial compressive tests with the same backfill were used to reveal proportions of shear parameters between interface and backfill. Nonplanar interfaces with different roughness were shear tested for further comparison. A constitutive model for interface was modified based on Mohr Coulomb criterion, which could used to investigate interaction between backfill and rock mass. Numerical simulated shear stress strain were used to validate the model. Book Name: Minefill 2020-2021 |
