DETONATION TRIODE (VERSIONS) Russian patent published in 2014 - IPC F42B3/10 F42C19/00 F42C15/34 

FIELD: blasting operations.

SUBSTANCE: in the first embodiment of the detonation triode, consisting of the detonation channel with two inputs and the partition adjacent to it, separating the channel from the triggered explosive charge, the partition is a separator made in the form of stick of the explosive composition of less sensitivity than the explosive composition of the channel, with dimensions insufficient to trigger the stick at unilateral passage of the detonation along the channel within the size of the stick. In the second embodiment of the detonation triode, consisting of the detonation channel with two inputs and the partition adjacent to it separating the channel from the triggered explosive charge, the partition is a separator made in the form of a package of perpendicular to the axis of the channel alternating plates of the explosive composition and of the inert material. The thickness of each plate of the explosive composition is insufficient to trigger it at unilateral passage of the detonation along the channel, and the thickness of each inert plate is sufficient to trigger detonation in adjacent plates of the explosive composition in collision in front of its end of the detonation waves coming from the inputs of the channel.

EFFECT: increase in reliability, reduction of time of transmission of detonation, increase in accuracy of the calculation of time of the detonation triode through the use of a single detonation physico-chemical process.
