Claims6
A detonator assembly (10) which includes a detonator (28), a holder (14) which comprises a spool (14), a flexible elongate element (40) which is coiled on the spool (14), an energy storage device (26) on the spool (14), a communication device (30B) which is mounted to the spool, a secondary inductive coil (32) which is mounted to the spool wherein the spool is movable relative to a magnetic field thereby to induce current into the coil which current is used to charge the energy storage device wherein initially the energy in the energy storage device is inadequate for firing the detonator and wherein movement of the coil through the magnetic field transfers adequate energy into the energy storage device to enable the detonator assembly to become operative and to fire the detonator.
