Study on Distribution Characteristics of Damage Range along Smooth Blasting Hole Based on PPV

Study on Distribution Characteristics of Damage Range along Smooth Blasting Hole Based on PPV

The damage range of surrounding rock has an important influence on optimization of blasting parameters. This study, based on the vibration attenuation law near the blasting source and the characteristics of the load acting on the wall of the smooth blasting hole, derives the distribution formulas of...
