(57) Abstract : Disclosed is an electronic detonator delay
assembly (24), having an associated detonator (12), that can be
pre-programmed on site with a time delay and installed in a
borehole to carryout a blast operation. The assembly is first
coupled to a programming unit (50) to program the desired
time delay, and then to a blasting unit (100), by means of a
magnetic coupling device (24) in the electronic delay assembly
and to a single pass of a conductive wire (22) through the
magnetic coupling device. The programmed time delay in the
electronic delay assembly can be double checked through a
wireless communication link (6) between the electronic delay
assembly and the programming unit.
