ABSTRACT

Peak particle velocity is the most important criterion for analyzing dangers
resulted from ground vibration. According to the investigations, this parameter
can independently indicate the possible damage and is proportional to it. Up
to now, investigators have proposed many different formulas to calculate this
parameter, but none of them are applicable for all areas and based upon regional
conditions such as geological, technical, geotechnical, rock mechanical and so
on, only one of these equations can be adopted. Karoun3 Project is located in
southwest of Iran, in an area with Asmary and Pabdeh formations. Peak particle
velocity criterion is used to predict blast effects on the structures of this project.
For this purpose, some blasts are carried out and in each blasting sequence,
peak particle velocity, charge weight per delay and distance from blast centre
have been measured. In the next step, two equations for prediction of peak
particle velocity are developed using curve fitting. The optimum drilling and
blasting patterns can be designed using these equations.
