P/8815/LIN 23 ABSTRACT Explosive Arrangement An explosive arrangement includes an explosive charge 22 which is detonated simultaneously from each end to produce opposing detonation fronts in the explosive. When the fronts meet, an outward force results which is used, for example, to cut through drills which have become jammed in a bore hole. The simultaneous detonations are produced by transmitting an electrical pulse along a stripline 35 via two EFI initiators 33 and 34 connected electrically in series by the stripline. An end plate 32 is located adjacent to one end of the charge 22, being clamped in use on a central shaft 24. The end plate 32 is movable to allow variable lengths of charge to be used. Another plate 38 is also movable on the shaft 24 and by suitable adjustment enables one length of stripline to be used for different length charges. Figure 2.
