Abstract: Technology for in situ remediation of undetonated explosive material. An explosive apparatus contains an explosive material in close proximity with a carrier containing microorganisms and with nutrient for the microorganisms. An explosive mixture capable of self remediation includes an explosive material that is intermixed with or lies proximate to the carrier. The microorganisms are either mobile or temporarily deactivated by freeze drying until rehydrated and remobilized. The microorganisms are capable of metabolizing the explosive material. Examples of such microorganisms include Pseudomonas spp., Escherichia spp., Morganella spp., Rhodococcus spp., Comamonas spp., and denitrifying microorganisms. If the explosive material fails to detonate, the explosive is remediated by the action of the microorganisms. Remediation includes both disabling of the explosive material and detoxification of the resulting chemical compositions.

Abstract: Technology for in situ remediation of undetonated explosive material. A bioremediating apparatus in the form of a storage chamber houses in moist condition type of microorganisms capable of metabolizing the explosive material. Examples of such microorganisms include Pseudomonas spp., Escherichia coli, Morganella morganii, Rhodococcus spp., Comamonas spp., and denitrifying bacteria. The bioremediating apparatus is joined with an explosive apparatus that houses a charge of explosive material. A solution released into the storage chamber by opening a first valve hydrates the microorganisms. The explosive assembly has an actuation means for opening the first valve and a second valve that releases the microorganisms from the storage chamber to begin metabolizing the explosive material, when the explosive apparatus is joined with the bioremediating apparatus. If the explosive material fails to detonate, the explosive is remediated by the action of the microorganisms.

Abstract: A slider (36) has a base fixture (40) and a shielding tube (42). The slider (36) is used to operably couple a detonator (44) to a detonating cord (62) that passes through a booster device (10), i.e., to prevent the detonating cord (62) from directly initiating or fracturing the booster (10). The base fixture (40) includes input lead-retaining means for disposing the input lead (47) of a detonator (44) in signal transfer relation to the detonating cord (62). Optionally, the slider (36) has a detonator retainer (38) for carrying the detonator (44) on the slider (36). Preferably, the detonator retainer (38) is able to hold detonators of various lengths in proper position to initiate the booster device (10). By disposing the shielding tube (42) on the slider (36) a booster device (10) can be used with various detonating cords (62) and a slider (36) having a shielding tube (42) suitable for the chosen detonating cord (62) can be inserted into the booster device (10).

Abstract: A booster for high efficiency initiation of an explosive material comprising a body portion having substantially tapered sides and a substantially flat interface surface at the larger end of the body portion extending generally laterally thereof for contacting the explosive material. A plurality of passageways may be formed in the booster to receive a means for detonating same. When compared with traditional cylindrical boosters of either equal weight or equally sized interface surfaces, the disclosed booster resulted in shorter run-up distance and a more effective release of explosive energy. Although numerous geometric configurations of the booster are disclosed, a presently preferred embodiment thereof takes the shape of a conical frustum, the larger planar surface of which is to be oriented as the interface surface toward the explosive material to be detonated.
