DETONATING DEVICE

摘要

CIL 599 An improved cord-like detonating device is provided for use in non-electric blasting methods. The device comprises a substantially standard detonating cord length wherein a central longitudinal core of the cord consists of a hollow, low energy shock wave conductor. The device has particular utility in long hole blasting with toe priming. Initiating energy can be transmitted down the hole to the toe primer charge through the low energy shock wave conductor. The detonating primer initiates the outer detonating cord sheath which transmits energy to set off additional primer charges attached thereto.
