      Stone fortifications materials (riprap or jetty stone and coarse rock) required for coastal protection structures under the Black Sea Coastal Highway Construction Project are supplied from quarries applying mostly coyote blasting (gallery blasting) method. Coyote blasting offers dangerous environment (fly rock, ground vibration, etc.) in terms of job security and structural damage in nearby residences. Therefore, an environmentally secure blast based excavation is required both to produce desired category stone fortifications materials and to minimize environmental problems.

      The results obtained from the bench blasting to produce the stone fortifications materials have provided the desired categorical distribution for the coastal protection structures. Materials produced from the above quarries are understood to be used as stone fortifications materials in the coastal protection structures and thus are suitable to the standards. Vibration parameters (peak particle velocity, acceleration, displacement, etc.) induced from coyote blasting is fairly high values and has shown the potential damages to the structures. Bench blasting for minimizing environmental problems and for the safety of workers and equipment was understood to be the most appropriate production method. Finally, the proposed bench blasting design according to the Kuz-Ram model was determined to ensure the production of desired category stone fortifications for the Black Sea Coastal Highway Construction.
