Abstract

Vibration measurements for 3 types of quarry rock at a number of sites in Thailand have been carried out and analyzed. The dominant vibration parameters in bench blasting are based on the peak particle velocity and the blast frequency. These readings are evaluated using the threshold limit of damage and the probability method. Results indicate that the damage possibility is low and within the acceptable limit. A further step of evaluation is to predict the safe distance from vibration by utilizing the modified trend line. This paper also describes steps taken in the planning stage to determine the optimal design model for a particular quarry area.
