"One of the most recent developments in blasting practice is that of applying the principle of short period delay electric blasting. In this type of electric blasting, instead or having all holes fire at one time, each hole or group of holes is a shot in itself. To provide a short period delay, of a few thousandths of a second, between each hole or group of holes, either millisecond (split

Blasting operations create significant problems to residential and other structures located in the close proximity of the mines. Blast vibration is one of the most crucial nuisances of blasting, which should be accurately estimated to minimize its effect. In this paper, an attempt has been made to apply various models to predict ground vibrations due to mine blasting. To fulfill this aim, 112
