  • Chapter 8 BLAST DESIGN

    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. High-energy explosives enhance fragmentation, which ultimately produces a positive effect on production

    Oct 12, 2012· In construction and in surface mining, millisecond delays are used between charges in a blast. There are several basic reasons for doing so: To assure that one or more free faces progress through the shot, providing a consistent burden. To enhance fragmentation between adjacent holes. To reduce ground vibration and airblast.
