Certain vibrational waves are formed as a result of open quarry blasts. The peak particle velocity occurred by these waves provides that structures and people present around the blast point are negatively affected. Thus it is very important that the peak particle velocity is minimum value. In this study, a new laboratory blast technique has been presented for reducing the peak particle velocity formed by vibrational waves occurring as a result of the blast. Two different experiments were carried out in the laboratory. In the first experiment, three peak particle velocities were measured normally. But, in the second experiment, the peak particle velocity value was measured by using the laboratory technique proposed. After that two experiments are compared each other. As a result of the study, it is realized that the proposed technique has considerably reduced the peak particle velocity values.
