摘要：

In order to obtain a better understanding of the non-ideal detonation characteristics of ANFO explosive (ammonium nitrate and fuel oil mixture), detonation velocity and pressure were measured in steel tubes simultaneously with ionization probes and piezo-resistive manganin gauges. Observed detonation velocity and peak pressure were compared with the theoretically predicted values made by the thermohydrodynamic CHEETAH code. Experimentally observed detonation parameters were determined as 60 to 72 % of the calculated detonation velocity and 42 to 58 % of the calculated detonation pressure. Furthermore the fraction reacted at the detonation front was estimated as 57 to 73 % of the ideal detonation calculated values.
