Özet: This study focuses on a relatively neglected topic of the effect of the blast induced vibrations on humans. The vibration monitoring was performed in an Istanbul region quarry. Nine different predictor equations were created for ground vibration. Absolute errors, percentage errors and scaled errors were applied to determine the most successful equation. The equation, which relies on cube root scaled distance concept, was determined as most successful predictor. The blast vibration was estimated by the selected equation considering the measurement distance. Human response to ground vibration was evaluated based on the predicted values. The criterion, which considers particle velocity, frequency and vibration duration together, was found to be reliable for evaluation. Additionally, a criterion proposed for pile driving was suggested for evaluation of blast induced ground vibration. The amount of maximum instantaneous explosive charge was calculated to meet the requirements of the vibration limits for the studied quarry.
