Method & governance

Built for transparent engineering review.

Pattern quantities

Geometry, charge, rock volume, tonnage and powder factor update from the entered bench design.

Vibration screening

Square root scaled distance relation. Replace K and n with site regression from monitored data.

Fragmentation

Kuz-Ram estimate with entered rock factor and relative weight strength. Treat outputs as comparative.

India compliance

Review current DGMS directions, approved danger zone and site permissions. A competent blaster remains responsible.
