Direct control Explosion Method suppresses the vibration at blast while insulting auxiliary material which controls the vibration. As this method lets explosion in the perforation on the bedrock, the shock waves occurred at the explosion concentrate at the planned area of excavation in order to destroy the bedrock. To prevent shock waves for unnecessary area of excavation the stronger blocking material which stainless or carbon fiber is insulted is used.
This method lets shock waves at the explosion in the certain direction to excavate the planned area only. Therefore, the shock wave is blocked in the unplanned direction by the Direction Control Device, so it prevents propagating the blasting vibration. It is known as non-vibration explosion method.
