Accidental Detonation in Underground Munitions Storage Magazines: Prediction of Cover Rupture Overpressures

Abstract

The Shallow Underground Tunnel/Chamber Explosion Test provides the only known airblast overpressure data produced by venting of the overburden cover from a decoupled high explosive detonation in a large-scale underground munitions storage chamber. A limited amount of overpressure data are available from fully-coupled underground high explosive detonations in alluvium (Buckboard 11 and 12, Stagecoach II and III, and Scooter events (Snell et al, 1971)) , two recent tests in a recompacted soil media (Midnight Hour I and II), and small-scale Norwegian model tests in sand (Jenssen, 1979). This paper describes procedures used to develop prediction curves for overpressures produced by airblast venting through the rupture of the cover rock over an accidental explosion in an underground magazine.
