DERIVATION OF GUIDELINES FOR BLASTING FLOATING ICE

Empirical prediction curves for ice blasting are given, and their derivation and use is explained. Alternative forms of the curves, which relate more closely to conventional underwater explosion technology, are developed and examined. Results of experiments with gas blasting devices are summarized and discussed in relation to the cratering effects of conventional explosives. There is a brief discussion of the energetics of ice fragmentation, effects of surface charges are outlined, and penetration by shaped charges is described. Some test data that were not previously available are given in an appendix.
