| A method for initiating a low-sensitivity explosive charge includes initiating a booster explosive charge within an explosive charge cavity in a booster housing, and generating a planar detonation wave. Generating the planar detonation wave includes directing a detonation wave through the booster housing along a first waveshaper surface of a detonation waveshaper. The detonation wave is directed around the first waveshaper surface toward a second tapered waveshaper surface. After progressing around the first waveshaper surface, the detonation wave is directed along the second tapered waveshaper surface. The detonation wave changes into a planar detonation wave as the detonation wave moves along the second tapered waveshaper surface, the planar detonation wave includes a planar wave front. The planar detonation wave strikes a flyer plate coupled over the explosive charge cavity of the booster housing, and the planar wave front makes planar contact along an inner face of the flyer plate. | ||||||

| 164 | METHOD AND APPARATUS FOR CONTROLLED SMALL-CHARGE BLASTING OF HARD ROCK AND CONCRETE BY EXPLOSIVE PRESSURIZATION OF THE BOTTOM OF A DRILL HOLE | EP96935776 | 1996-08-02 | EP0842391A4 | 2001-03-14 | WATSON JOHN DAVID; MICKE BRIAN P |
| Rock and other hard materials, such as concrete, are fragmented by a controlled small-charge blasting process. A cartridge (200) containing an explosive charge is inserted at the bottom of a short hole (240) drilled in the rock. The explosive charge is configured to provide the desired pressure in the hole bottom, including, if desired, a strong shock spike at the hole bottom to enhance microfracturing. The cartridge (200) is held in place or stemmed by a massive stemming bar of high-strength material such as steel. The cartridge (200) incorporates additional internal volume designed to control the application of pressure in the bottom hole volume by the detonating explosive. The major features of the method and apparatus are the relatively low-energy of the flyrock and the relatively small amount of explosive required to break the rock. | ||||||

| A cartridge (1) comprises a cartridge case (3) in the base of which an ignition chamber (5) containing a detonating agent (6) is arranged, a pressure cartridge (7) which forms a high-pressure chamber (8) filled with a cartridge propellent, and a projectile (2) lodged in the case (3). The high-pressure chamber (8) of the cartridge (7) communicates via an ignition channel (9) with the ignition chamber (5) and via at least one gas outlet opening (10) covered by an insulating insert (13) with a low-pressure chamber (11) between the projectile (2) and the case (3). To ensure uniform pressure and combustion conditions in the high-pressure chamber and thus to ensure more accurate aim, the ignition channel (9) extends axially through the high-pressure chamber (8) as far as the gas outlet openings (10) and the outlets from the ignition channel (9) are directed radially and/or directed onto a radial deflecting surface. | ||||||

| An explosive booster (10) shaped to fit into a blasthole adjacent a main explosive charge is provided. The booster (10) comprises a body (12) containing a charge of an explosive substance (22) with a passage (24) extending inwardly of the body (12) to receive a detonator (26) therein. The booster (10) is configured to alter the shape of a detonation wave generated upon initiation of the detonator (26). In an embodiment, the booster (10) includes a first (32) and a second explosive substance (34), with the first explosive substance (32) being shaped and selected to cause an outer portion of the detonation wave to accelerate relative to the remainder of the wave thereby altering the shape of the wave from a generally spherical wave to a generally planar wave. In an embodiment, the booster includes an internal member capable of altering the shape of the detonation wave. | ||||||

| A cost-effective solution is proposed to improve explosive transfer between booster (50) and warhead that is compatible with the existing base of general purpose warheads and flexible to work with new warhead configurations. A booster lens (52) is placed in the fuze well (20) that concentrates the pressure wave to penetrate the fuze well with a peak pressure that exceeds the detonation threshold and detonate the warhead explosive (24). The booster lens can be configured to control the direction of the concentrated lobe to penetrate the fuze well where the barriers are low. | ||||||

| A gas generator (10) is provided, comprising an initiator (48) including an initiator charge, a gas generant insert (52) spaced apart from the initiator (48), and a fluid-impermeable blast director (42) interposed between the initiator (48) and the gas generant insert (52). The blast director (42) provides a barrier between the gas generant insert (52) and a blast resulting from ignition of the initiator charge when the initiator charge is ignited. The blast director (42), when used with particular gas generant configurations, reduces the effects of the initiator blast and reduces the amount of gas generant exposed to the blast, enabling the structural integrity of the gas generant (52) to be maintained. | ||||||
