Résumé du livre
The report presents the results of preshot and postshot geologic and engineering properties investigations performed in conjunction with the Project Pre-Gondola I cratering experiment series. The Pre-Gondola I series consisted of the detonation of four 20-ton HE charges at varying depths of burst in highly over-consolidated Bearpaw clay shale at Fort Peck, Montana. Detailed surface and subsurface postshot investigations were conducted at the Bravo crater. Surface postshot investigations only were conducted at the other crater sites. (Author).
