We have compared a special character(pressure of explosion, gas volume, energy of explosion, temperature of explosion, strength) of different three emulsion explosives which is different velocity by Nitrodyn program that is calculated explosion reaction. We have analyzed the character of the vibration from a vibration data which is a result from test blasting in different velocity of detonation for three emulsion explosives of the same size(17mm) in the same rock. As a result, the vibration is decreased when the velocity of detonation is decreased within 40m from origin of explosion but it is familiar character over 40m, so there isn't much affect the velocity of detonation in decreased vibration over 40m.
