Abstract : This study investigates the potential performance of self sealing chambers in rock as a means of containing the blast effects from an accidental explosion in an underground ammunition storage complex. The work was performed as part of the Joint U.S./ROK R&D Program for New Underground Ammunition Storage Technologies. A coherent method for modeling of self sealing systems is presented. This method illustrated that observations made during field investigations can be incorporated into simulation models for realistic prediction of the behavior of storage chambers during an accidental explosion. The modeling approach incorporated a thermodynamic/numeric technique using a distinct element numerical code (UDEC). Three self sealing scenarios were modeled: a sliding block a weak wall exhaust drift, and a single weak wall. The performance of the weak wall exhaust concept was superior to the other designs evaluated. The analysis indicated that this self sealing design was most successfull for reduction of the escaping gas pressure.
