Abstract

In this paper，the calculation formula of blasting vibration velocity was analyzed and generalized. Based on similarity theory, the formula to estimate the blasting vibration velocity had been derived. In the same terrain, geological conditions and explosives，the ground vibration velocity depends on Maximum amount of primary explosive（Q），distance from Explosion source to measuring point（R） and blasting action index（n）. The calculation formula which was put forward by previous USSR scholar is useless unless standard throw blasting and concentrated cartridge. Finally, according to equivalence principle ，linear charge was assumed to be numerous equivalent concentrated charge，the equation of deep-hole blasting was derived，and it was successful in practical engineering applications
