| titleOfInvention | Tunnel face full-section smooth blasting initiation system network |
| abstract | The invention discloses a full-section smooth blasting initiation system network for a tunnel face, and provides a safe and reliable full-section smooth blasting initiation network for the tunnel face. The detonation network comprises an electric detonation device and a non-electric millisecond differential detonation device; the electric initiation device comprises an exploder and an electric detonator connected with the exploder through a booster lead; the non-electric millisecond differential detonating device comprises a plurality of non-electric millisecond differential detonating units, each non-electric millisecond differential detonating unit comprises a first plastic detonating tube, a non-electric millisecond delay detonator and a plurality of second plastic detonating tubes, the first plastic detonating tubes are connected with the input ends of the non-electric millisecond delay detonators, and each second plastic detonating tube is connected with the output end of the non-electric millisecond delay detonator in a cluster manner; each first plastic detonating tube is connected with an electric detonator in a cluster mode, and each non-electric millisecond differential detonating unit is connected in parallel. The invention combines the advantages of electric detonation, non-electric detonation and millisecond differential detonation systems, and is beneficial to improving the safety and reliability of blasting. |
