Abrégé
There is disclosed an explosive cartridge that is self deactivating if detonation does not take place as intended. The explosive cartridge comprises: an outer shell surrounding an explosive composition; a deactivating agent that is capable of desensitising the explosive composition and that is provided in a form that is rendered mobile on contact with water; and a barrier element that is provided between and prevents contact between the explosive composition and the deactivating agent. The cartridge is adapted to allow water from the environment to enter, or be delivered into, the cartridge and come into contact with the deactivating agent, thereby rendering the deactivating agent mobile. The barrier element is adapted to be breached or at least partially removed when the deactivating agent has been rendered mobile by contact with water from the environment that enters or is delivered into the cartridge so that the deactivating agent will come into contact with the explosive composition. When mobile, the deactivating agent will contact the explosive composition and will render the explosive composition insensitive to detonation after a predetermined period of time by which detonation of the explosive cartridge should have occurred but has not occurred. The present explosive device advantageously self-disarms when contacted with water.

Method of blasting multiple layers or levels of rock
A method of blasting plural layers of material (38, 40, 42, 44) in a blastfield (16) that reduces the amount of mechanical excavation required to expose a lower layer of material. The method includes using rows of equally spaced blastholes (18, 20, 22, 24) that pass through all of the layers and additional intermediate rows of blastholes (26, 28) that pass down only through top layer (40). Each blasthole is capped with stemming material and includes one or more decks of explosives material (46) and detonators (48), with air decks or inert stemming (45) separating adjacent explosives decks (46). The detonators in layer (40) are detonated first in order from row (18) rearwards to throw a substantial amount of the blast material from layer (40) forwardly of free face (12) onto floor (34). In the same blasting cycle and within seconds of the throw blast, explosives material in layers (42, 44) is detonated in a stand-up blast in which material in layers (38, 42, 44) is broken up but otherwise minimally displaced or thrown forwardly. Layers (38, 44) may be coal seams which are separated by interburden layer (42) and covered by overburden layer (40).

Fire, arm, and disarm signals are typically transmitted to electronic detonators via signal transmission lines. Traditionally, such signal transmission lines include wires wherein one end of each wire is soldered directly to printed circuit boards and/or other signal processing components retained within the shell of a detonator. Other ‘modular’ blasting apparatuses of the prior art provide means to connect signal transmission lines to detonators in the field. Signal transmission line/detonator contacts are susceptible to disruption, particularly when the signal transmission lines are subject to inadvertent tugging or tensile forces at the blast site. The present application discloses an electrical connector that enables secure connection between a signal transmission line and any detonator adapted to receive and optionally process electrical signals from the signal transmission line. Specifically, the electrical connector can be affixed to the signal input end of a detonator, and includes at least one bridge element to provide electrical contact between a signal transmission line, and internal electrical component(s) of the detonator.
