Abstract
A passive detonation cut-off device for a solid line of explosives operates by directionally controlling the detonation pressure of an accidental detonation wave of an explosives line and by using this directionally controlled detonation pressure to sever the explosives line to prevent further propogation of the detonation wave. The device comprises a body having two through holes extending through the body and at least one blast hole connecting the through holes and extending from one of the through holes to the outside of the body.
