Context 1
... Electronic initiation technique with multiple initiation points should be adopted where possible to move ore into ore and waste into waste ( Figure 11). ...
Context 2
... blast timing can achieve highly efficient separation between ore and waste. Figure 11 shows the results from blast 310_003. The audit also identified that there has been significant blast movement into the pit void causing the berms to be filled (reducing the catch bench capacity) and loss of ore (in the case of ore blasting). ...
