In order to obtain a better understanding of the non-ideal detonation behaviour of ammonium nitrate based explosives, detonation
velocities of ANFO (ammonium nitrate and fuel oil) prepared with different kinds of ammonium nitrate (AN) were measured in
steel tubes. In this series of test six kinds of AN were used and the influence of the pore diameter, the pore volume and the particle
diameter of the AN particle on the detonation velocity of ANFO was investigated.
