Chapter 8 BLAST DESIGN - National Park Service

To obtain well-fragmented rock by blasting, explosive energy must be well distributed throughout the rock. To be effective in rock blasting, this energy must be applied at the proper millisecond delay interval to allow for optimum rock movement. The type and cost of explosives will vary from one operation to another, dependent upon many conditions.
