A hybrid RF–PSO–BiLSTM model for blast fragmentation prediction
Blast fragmentation is a key indicator for evaluating blasting performance, but its accurate prediction remains challenging because of the nonlinear coupling among blasthole geometry, explosive energy input, and rock-mass properties. In this study, a hybrid RF–PSO–BiLSTM model was developed using 90 field blasting case...
