ABSTRACT:
A low-energy blasting initiation system, method and surface connection is disclosed for low-noise, time controlled transmission of an initiation signal from a signal initiation source to a plurality of remote blasting elements. A connector block of the system comprises a housing having a channel formed therein for receiving a low energy detonator. A tube engaging member is formed on an end of the housing for holding transmission tubes adjacent an end of the channel. Tabs are formed in the channel for snap-fit retention of the detonator, and positioning cleats are formed in the channel for positioning of the detonator with an explosive end of the detonator in juxtaposed energy communicating relationship with a side of the transmission tubes. Non-directional signal transmission is initiated in the transmission tubes in response to activation of the detonator for time-controlled transmission of the initiation signal to the remote blasting system elements.
