Recent studies of airblast from buried charges, for environmental charges, for environmental protection from HEST events
Characteristics of blast waves from explosions in simple geometries and containment media have been well defined by hydrodynamic models and verified by experiment. A large class of useful explosions, those only partially contained by the close surrounding medium, are less-adequately understood. This report addresses the problem of airblast emitted into the atmosphere from explosions buried in the ground at less than containment depth. Examples of such explosions have arisen in cratering excavation, mining and quarrying, ordnance disposal, and military High Explosives Simulation Tests (HEST). Some recent HEST data have been assembled here to help define an empirical approach to airblast predictions, for operational safety as well as for controlling environmental impact on neighboring communities.
