In the explosive processing using the underwater shock wave generated by underwater detonation of an explosive, it is very important to control the underwater shock wave for a purpose of the processing. Therefore, a new control technique of the underwater shock wave using the 2-dimensional spiral detonating cord was developed. The pressure of underwater shock wave generated from 2-dimensional spiral detonating cord was measured by the pressure sensor. From the result of the pressure measurement, it was found that the maximum pressure and the impulse could be control by varying the distance between the spiral center and the pressure sensor.
