Hybrid shock tube/LEDC system for initiating explosives

摘要: In a non-electric system for initiating explosives, shock tube is initiated by the detonation of low-energy detonating cord (LEDC) whose wall has been placed adjacent to an initiation-sensitive region thin membrane in tube, or capping member open end detonator itself, wherein inner surface bore end-capping coated with reactive composition explosive deflagrating compound. The fits over and seals without it, acting as itself. accepts from LEDC, whereby relays pressure pulse affixed thereto. Novel tubes, tube/detonator units, use hybrid tube/LEDC are disclosed.
