Abstract

This article examines the relationship between the velocity of detonation (VOD) of explosives and the p-wave velocity of rocks. The correlation between these two parameters plays a significant role in the utilization of explosive energy in rock blasting. While there's a general consensus that matching the VOD with the p-wave velocity can lead to favorable blasting results, differences between these velocities are not uncommon in practical applications. Using Huygens' principle as a foundation, the article explores how these differences affect crater formation in rock blasting.
