Prediction of Fragment Range for Responding Magazines Based on the Bakhtar Explosives Safety Criteria
Abstract
An innovative and cost effective method is presented for prediction of hazardous fragment range resulting from accidental detonation in an underground explosives storage magazine. The approach is unique in terms of its formulation and data requirements. It is formulated by defining two new terms namely; dynamic response factor (R) and load capacity factor (C) describing the characteristics of the engineered and geologic systems. The required site specific data are obtained by performing non-destructive index tests on the geologic and engineered systems in the field. This work is an extension of the Bakhtar Explosives Safety Criteria developed for storage of explosives in underground structures. The verification of the empirically formulated approach has been done through a series of scaled model tests conducted under the normal gravity (1-g). The research was sponsored through the Department of Defense SBIR Phases I and II programs under contract with the United States Air Force. The formulated criteria and associated characterization methodology can also be used for siting, loading density optimization, site selection, site investigation to determine communication between adjacent magazines, estimation of required depth of rock cover for a given loading density, safe design and construction of underground munitions storage magazines.
