Flyrock & Mandatory Exclusion Radius
Lithology Change - Pull Efficiency Impact
Uses your current Drill & Load design (actual powder factor) to estimate how well the round/pattern would pull if the face changes into a different rock type. Green = full pull expected, Yellow = marginal, Red = redesign before firing.
