      The full impact of rock blasting on the environment includes ground vibrations, air blast, fly rock and dust, and unavoidable in quarry operations if they are not controlled. The detonation of explosives for rock breakage induces a seismic disturbance which propagates in all directions from the explosion epicenter. Ground-borne vibrations from blasting are readily perceived in nearby residences and sometimes result in legal action alleging structural damage. However, in addition to the seismic disturbance, the detonation of explosives causes a transient pressure pulse which is propagated through the atmosphere. This phenomenon has been described in the literature as an air blast. Fly rock in rock blasting has been a series problem since blasting began several hundred years ago. Men have been killed; building, equipment, and material destroyed. These hazards are greatest in urban areas. The need for large coarse rock material, along with increased loaded/unloaded vehicle weight, higher travel speeds, and the movement of rock by blasting can create a fertile environment for greater dust generation. Additionally, blasted rocks are transferred from face to the final dumping place by haulage trucks using existing highways under hazardous (uncontrolled) conditions such as falling coarse rock on roads, bringing about traffic jam, etc.

      In this study, it is discussed the problems of Bulak Quarry in Trabzon - Bulak Village 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 owner to use cautious blasting system with a number of benches and therefore decreasing the amount of explosive per delay to reduce the environmental effects of the quarries under running undesirable conditions.
