Abstract: With the blasting production of Muliashy Open Pit Mine as engineering background，the vibration formula about elevation amplification effect was obtained via dimensional analysis on the physical quantities that affects the attenuation of blasting vibration velocity.By twice checking on the blasting production test data and the comparative analysis，it is founded that the error about vibration velocity calculated through the traditional Sodev′s empirical formula is large when the terrain elevation in the blasting monitoring test varies obviously，with the average error of 40.7%.The error of the calculated velocity through the improved formula of the dimensional analysis is smaller，with average error of 13.3%.The results indicated that the improved formula of blasting vibration velocity via dimensional analysis method can more accurately reflect the elevation magnifying effect of propagation medium on blasting vibration velocity，and its regression result are more realistic.
