Open Pit Wall Control Analysis using Photogrammetry

Back-break induced from blasting is a concern in open pit metal mining because it compromises the conditions of the pit’s final walls. Final walls that have excessive blast induced damage commonly require extra attention and can often lead to increased cycle times. Most importantly however, the safety conditions of a back-broken region can be significantly compromised and it must be addressed to prevent injury and/or damage to equipment. This occasionally results in the necessity to alter mine plans to prevent an incident from occurring in a back-broken region which can be costly to the mine.
