vibration was established based on grey relational analysis and gene expression programming (GRA-GEP) with the theory of grey correlation degree and MyEclipse development tool. Based on blasting data... formula (the average error is 30.6%) and the BP neural network (the average error is 13.3%). Key words: blasting vibration; blasting-vibration-peak-speed; GRA-GEP; gene expression program; forecast......
