The main objectives of backfilling in underground stopes are to improve ground stability and reduce ore dilution (Li and Aubertin, 2014). Consequently, the placed backfill in an open-face stope must possess a minimum backfill strength to remain self-standing during mining of an adjacent stope. Meeting specific backfill strengths requirements is essential for ensuring the effectiveness and safety of the operation. The purpose of this example is to evaluate the behavior of the backfill in an underground stope following mining adjacent block and exposing the end wall. Another simulation is performed to evaluate the factor of safety associated with mining underneath the backfill. Author: Nawfal El Mkadmi Link to download |
