A Re-Assessment of an Existing Underground Explosives Storage Facility in the UK,
Abstract
A series of trials using 1/24th linear scale models of buried magazines have been carried out to determine the distance at which an air-blast peak overpressure of 50 mb, normally identified with the Inhabited Building Distance, would be produced on detonation of the stored explosive. This paper presents the methods by which the magazines and explosives stores were modelled and summarises the results obtained by investigating both structural and overstrong models. The paper concludes that the 50 mb overpressure region occurs at a maximum distance of 6 Q1/3 for a structural model and 16 Q1/3 for an overstrong model, where Q is the weight of explosives in kilogrammes. This is in a direct line with the adit from the magazine and is considerably lower than the ESTC prescribed distance of 30 Q1/3. (Author)
