Monitoring and Analyses on Blasting Vibration of a Thousand-ton Charge Level Long-hole Casting Blasting Project

摘要

Design of a thousand-ton charge level long-hole casting blasting project and vibration monitoring were conducted in this paper. Through blasting vibration record in different direction, the effect of presplit crack of vibration reduction was discussed, the application of millisecond hole-byhole blasting was studied, and the features of blasting vibration wave of the large scale long-hole casting blasting were also analyzed. Above research are helpful for further optimization of blasting parameters.
