He attended the University of Arizona, graduating in 1939. He served in the Army in World War II and retired as a Lt. Col. in 1977. Rabb worked in mining and metallurgy. In addition to working at the Lawrence Livermore National Laboratory, he worked for the Army Inspector General’s Office, Battelle (Columbus); Arizona Bureau of Mines; and the University of Arizona. Abstract: Recent underground nuclear tests in tuff, alluvium, salt, and granite have yielded data essential to the evaluation of mining applications of contained nuclear detonations. The data indicated that for these media the cavity radius is predictable within +/- 20% without regard to the properties of the rock in the immediate shot environment. Properties of the chimney of broken rock resulting from collapse of the cavity, on the other hand, are found to be related to the properties of the rock and its preshot structural weaknesses. Seismic effects and radioactivity distribution are sufficiently documented to serve as a basis for predicting the safety conditions associated with detonations for a variety of yields. Condition: Good / No dust jacket issued.
