The radius of an air-filled cavity in hard rock required to decouple an underground nuclear explosion has been previously estimated to be about 25 meters W1/3 (KT). For yields of 10 KT and larger, the cavity size appears prohibitively large to mine in hard rock, both for economic and perhaps construction reasons. As a result, several test programs and theoretical effort have been conducted to investigate the use of heat absorbers to reduce the cavity size required. The principal problems associated with a heat absorber technique are in achieving adequate and rapid mixing of the explosive gases and the absorber material. The DIAMOND DUST , DIAMOND MINE and PRE-MINE DUST were test programs to study heat absorber concepts for quenching an explosion in a cavity.
