Prediction of Blast-Induced Backbreak Using Burden, Spacing, Powder Factor, And Geometric Stiffness

Back break, defined as rock fracturing that extends beyond the last row of blastholes into the intended final wall or the next bench, is a persistent problem in open-pit mining and quarrying that compromises slope stability, increases dilution, and raises downstream costs. This study develops an empirical multiple line...
