Abstract:

Relationships are outlined which permit the calculation of safe distances for prevention of propagation of detonation due to fragment impact between adjacent, potentially mass-detonating systems, for any assumed degree of risk and degree of acceptor shielding. These relationships permit prediction of probability of propagation in an existing situation, as well as calculation of necessary changes in acceptor shielding andor separation distances for any other degree of tolerable risk. All that is necessary to develop the specific relationship for a given situation is knowledge of properties of the explosives involved and geometries of the explosive systems. A simple method for graphically representing the relationships is presented.
