Study of the Effect of Particle Size Distribution on the Detonation Velocity of Modified ANFO

摘要：

In order to ascertain the relationship between the detonation velocity and the particle size distribution of modified ANFO, the modified ANFO are chosen as an object of this paper. By means of the time measurement method, and in light of the detonation velocity with different particle size distributions and charge densities, modified ANFO are tested under the same experimental condition. The experimental results showed that particle size distribution has an obvious effect on the detonation velocity of modified ANFO, the detonation velocity increases with the increment of the mass percentage of tiny particles (d<0.074 mm) in the same charge density, besides, the detonation velocity decreases with the increment of the charge density in a certain range of density.
