The aim of this thesis is to contribute to the understanding of the hangingwall failure process and its relationship with the ground surface subsidence. Results from numerical analysis using continuous methods indicate that the first tension cracks are formed ...
Molycorp, Inc.’s Questa Mine plans to switch from gravity draw in Block 1 to a load-haul-dump (LHD) draw system in the East and West blocks of the D Orebody. Changes in mining method require modifying the support design. This paper summarizes the numerical ...
