Channel Effect of the Modified Powdery Mixture of Ammonium Nitrate and Fuel Oil
The modified powdery mixture of ammonium nitrate and fuel oil (MPANFO) is a new breed of industrial explosives, which was developed years ago in China. As one of the important properties of an industrial explosive, the channel effect of MPANFO is reported for the first time here in China. A series of experiments was conducted to determine the channel effect of MPANFO. The blasthole diameter range was estimated to avoid the channel effect of MPANFO. Three empirical formulas for predicting the detonation length of MPANFO were provided in terms of the channel effect Experiments and theoretical analysis indicate that the channel effect of MPANFO is very serious. The reason why the channel effect of MPANFO is worse than that of other industrial explosives was explained at a theoretical leveL In addition, some properties of it, such as the sympathetic distance, the detonation velocity and the brisance, were determined.
