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-direction 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.

A low energy blasting initiation system surface connector block for retaining a low energy detonator having an explosive end and used to initiate non-directional signal transmissions in one or more transmission tubes having respective transmission tube longitudinal axes and outside diameters, the connector block comprising: a housing having a channel formed therein, the channel having a longitudinal axis and being dimensioned and configured for receiving the detonator as defined above with the explosive end of the detonator adjacent one end of said channel; a resiliently deformable segment having a first end and an opposite end and being fixed at said first end to said housing, at least a portion of said segment being of a reduced thickness relative to the thickness of said housing; a tube engaging and gripping member fixed to the opposite end of said segment to form a slot between said housing and said member, said slot being disposed at said one end of said channel, said slot being of arcuate cross section and being dimensioned and configured to receive and retain therein the one or more transmission tubes disposed within said slot adjacent said one end of said channel, with the longitudinal axes of at least those portions of the one or more transmission tubes disposed within said slot being retained perpendicularly to respective lines taken parallel to the longitudinal axis of said channel and intersecting respective transmission tube longitudinal axes, said segment deforming in response to force exerted on said member for positioning the one or more transmission tubes in said slot; and positioning means on said housing for positioning the detonator within said channel with the explosive end of the detonator in juxtaposed energy communicating relationship with the slot whereby activation of the explosive end of the detonator so positioned in said channel initiates non-directional signal transmission in the one or more transmission tubes retained in said slot.
