      Blast induced ground vibration may cause damage to the structures in the surrounding area. Thus, the environmental problems caused by ground vibrations and air blasts have been frequently encountered in the industries such as mining, construction and quarrying where blasting is often used as a mode of operation. Therefore, the prediction of the magnitude of ground vibration to be induced is of great importance to prevent the damages to the structures close to the point of blasting.

      From the statistical analysis of the results, the general peak particle velocity equation PPV= 7236.7 SD^(-2.2616) was constructed with a correlation coefficient of 0.68 to predict the ground vibrations in the quarry for the blasting operations. High correlation coefficients were obtained when the data pairs evaluated for each bench. This suggested that the evaluation of the data for each bench should be treated separately. It was also found that 3.2%, %83.8 and 13% of blast induced ground vibrations had a frequency of 5-12 Hz, 13-40 Hz and higher than 40 Hz, respectively. These high frequencies have prevented structures from resonance and minimized the potential damage to the buildings. The intensity of the air blast in all measurements was recorded below 140 dB, which is the level of human annoyance. To minimize the damage to the building structures such as school, mosque, historic place and village houses located close to the quarry, different blasting design methods were proposed and the limit of operation area was determined.
