ABSTRACT

The full impact of coyote blasting on the environment includes ground
vibrations, air blast, fly rock and dust, and these are unavoidable in quarry
operations if they are not controlled. The detonation of explosives for rock
breakage induces a seismic disturbance that propagates in all directions from the
explosion epicentre. In addition to the seismic disturbance, the detonation of
explosives causes a transient pressure pulse that is propagated through the
atmosphere. This phenomenon has been described in the literature as air blast. Fly
rock in rock blasting has been a series problem since blasting began several
hundred years ago. These hazards are greatest in urban areas. In this study, authors
attempt to discuss the problems of quarries operated to produce riprap or jetty
stone and coarse rock material filling sea for Black Sea Coastal Highway
Construction Project in terms of environmental effects mentioned above.
Therefore, it is mainly aimed at discussing the quarry production method
employed and monitoring a series of blast events to asses the damage/nuisance
potential of each blast, and persuading quarry owners to use cautious blasting
system with a number of benches and therefore decreasing the amount of
explosive per delay and investigating of non-explosive applications for excavation
to reduce the environmental effects of the quarries under running undesirable
conditions.
