Abstract

Small-scale experiments were carried out using a model of an underground magazine in an explosion chamber. The propagation characteristics of the blast wave of the exterior of the magazine model resulting from an explosion within the magazine model were investigated. The main points of interest are the angle variation and the spatial attenuation of the blast wave overpressures. The experimental results show that the blast wave overpressures diminished with the distance from the exit of the magazine model and with an increasing azimuth angle measured from the centerline of the exit. Interestingly, the lowest blast overpressure did not appear at the rear of the magazine model. These results are useful for the design of safer storage facilities for explosives.
