ARRANGEMENT FOR EFFECTING DETONATION OF EXPLOSIVE MATERIALS

摘要

The invention relates to an arrangement for effecting detonation of a mass of explosives material comprising an electrical supply source (11), conductor means (12) for conducting electrical signals from said supply source to a detonator (15) and a programmable electronic device (13) in the electrical path between said electrical supply source (11) and said detonator. The programmable electronic device (13) is adapted to receive and to store a programme relating to the desired detonation of the explosive mass and the arrangement includes means for applying a signal to the electronic device (13) to initiate the desired stored programme. In one described embodiment the electronic device (13) includes means (13e) for testing the electrical circuit from the device (13) to the detonator (15) and for transmitting information relating to the programme and said electrical circuit to a signal receiving device via the said conductor means (12).
