Delay booster assembly |
摘要 |
A nonelectrically initiated delay booster assembly includes a booster shell containing an explosive material, a cap well extending through one end of the booster shell into the explosive material, a nonelectric delay cap in the well and a detonating cord tunnel surrounded by a shock absorbing material affixed to the side of the booster shell or enclosed inside the booster shell. A signal carrier extends from a point within the cap to a point adjacent a detonating cord extending through the detonating cord tunnel, and a sensor member is affixed to that end of the signal carrier that is external to the booster shell in such a manner that it is in initiating relationship with the detonating cord extending through the detonating cord tunnel. A plurality of these boosters can be affixed to a single detonating cord downline when conducting multi-deck blasting operations.
