FIRING ARRANGEMENTS

摘要

2076017 9210718 PCTABS00013 A firing arrangement for detonating secondary explosives includes charge storage means (2) a switch and a initiator (3) for producing a high energy pulse and transforming it into a form suitable for detonating secondary explosive, with at least two of the components being contained in a common unit suitable for hand-held use. This eliminates the need to use a conventional detonator containing primary explosive and also enables a particularly compact arrangement to be produced. In one particular embodiment of the invention, the initiator (3) is replaceable and included in a unit (29) which also houses the power supply, a capacitor and a switch.
