Project Sergius Narrows - Summary of Tests on Liesnoi Island, Alaska, 1970

Abstract

Project SERGIUS NARROWS, Liesnoi Island Tests, was executed during the period 8 June through 8 July 1970 in a granite medium on Liesnoi Island, Alaska. The tests consisted of attempts to spring fifty-seven small diameter drill holes to accept cratering charges, then detonating the holes sprung successfully as cratering charges. The spring tests indicated that hole springing in an intermediate to high strength rock is not economical due to the high probability of hole failure. The cratering results are sketchy but tend to indicate that the cratering criteria developed for high strength rock is valid for the granitic medium of Sergius Narrows, Alaska.
