Studies of the phenomenology of crater formation have been conducted at Duke University for many years with emphasis on the problems of large-scale excavation. This report reviews the findings of those studies, but with emphasis on their relevance to the concept of quarrying with large-yield explosions at relatively deep burial depths. Some simple rules are established for correlation of small-scale events under sloped terrain to analogous events under level terrain. Analyses are made of known cratering experiments in basalt and granite using the authors incremental approach as opposed to the conventional scaled depth approach. The results of these analyses are applied to the analysis of a proposed nuclear quarrying event at a hypothetical site in a granitic medium. Author
