DIAGRAM OF CONTROLLED DETONATION LOGIC CHAIN Russian patent published in 2012 - IPC F42D1/04 F42B3/10 

FIELD: blasting operations.

SUBSTANCE: invention refers to blasting operations, and namely to detonation systems intended for controlled detonation distribution from one or more initiating agents and initiation of several explosive charges or several places of one charge. It can be used in several spheres of blasting engineering to reduce the hazard of preparation of different explosive charges or devices containing them for explosion. The diagram of the controlled detonation logic chain consisting of the main channels on the basis of at least one AND logic element having at least two inputs and one output brought into action at least with one initiating agent connected to inputs of AND logic element also includes one controlled channel branching as per the number of AND logic elements. The controlled channel connects two points of one of the main chain channels led to each AND logic element so that its length is less than length of section of the main channel between those points.

EFFECT: improving reliability, shortening the time required for detonation transfer, improving the accuracy of calculation of detonation logic chain operating time owing to maintaining the integrity of the main chain channels.
