Title: DETONATOR LEAD PROTECTOR
Abstract:
A detonator lead protector comprises an applicator and an in-situ sheath. The applicator houses the sheath and in use applies the sheath to the detonator lead within a blast hole. The sheath is applied to the detonator lead as the applicator runs down the detonator lead along at least a portion of a length of the blast hole. The applicator has a first aperture through which the detonator lead is able to move, and may have a second aperture through which the sheath is able to pass as the sheath is applied to the detonator lead. The applicator also forms a separation between explosives and stemming material in the blast hole.
