Improved Strength Assessment for Cemented Backfill by ehess is a document available to read on EtoBox.
This paper presents an improved method for assessing the required strength of cemented backfill in underground stopes with an open face, addressing limitations in existing solutions. The authors propose a new limit equilibrium solution based on three-dimensional numerical simulations, which shows better agreement with experimental results compared to the previously established Mitchell solution. The findings indicate that the proposed solution effectively predicts the required strength and factor of safety
