Split-second blasting on st. Lawrence seaway
Technique requires detonation of holes of multiple hole blast to defined pattern at time intervals measured in milliseconds; first charge or group of charges initiates build-up of pressure within rock structure, and impact of succesive charges produces disintegrating action by striking rock at moment that formation is under stress; description of work on various sections of seaway.
