Abstract: 

Ground vibration due to blasting is the research subject of many investigations. A lot of works have been done in order to estimate the quality and quantity of this blasting outcome. Mathematical models proposed by various investigators are a noticeable result of these investigations. In this paper, the origin of these mathematical models are studied and the short comes are pointed out. With aid of real data a new empirical model has been proposed. This model is some modification of the previous ones with some different parameters. This investigation is based on analyzing the data obtained by operating 14 blasts in Sarcheshmeh Copper Mine whose data have been collected by seismographs installed in the area. In the proposed model, instead of the amount of charge exploded in each delay the amount of charge the vibration due to which is received in a certain time is concerned. This certain time has been determined to be 10ms for this mine. The application of the proposed model is compared with that of the previous models and with the real data. This comparison shows that the applicability of the new model is by far better than that of the previous ones.
