Chapter 8 BLAST DESIGN National Park Service
The economic analysis of the use of explosives is an important part of blasting operations in mining and construction. Explosives are energy, and the efficient use of this energy is a major factor in keeping rock blasting costs under control. Highenergy explosives enhance fragmentation, which ultimately produces a positive effect on production costs.
