    摘要： A support device (10) in the form of a plastics plug for supporting material comprising stemming (46) in the form of crushed stone and an explosive charge (48) in a blast drill hole (40) at a position wherein the material is spaced above a bottom wall (42) of the drill hole (40). The support device (10) comprises a cup-shaped material supporting portion (16) in which the material is supported and an elongate shank portion (18) which extends from the material supporting portion ( 16). The shank portion (18) has a tapering hollow conical configuration and is releasebly connected to the material supporting portion(16) in an arrangement permitting separation of the material supporting portion (16) from the shank portion (18) so that the material supporting portion (16) can be used separately in a mid-hole decking application.

    摘要： A mobile manufacturing and delivery platform that is adapted to provide in a blasthole an explosive composition comprising a liquid energetic material and sensitizing voids, the sensitizing voids being present in the liquid energetic material with a non-random distribution. The platform comprises a storage tank for the liquid energetic material; at least two delivery lines for conveying respective streams of the liquid energetic material from the storage tank; a void delivery system for producing sensitizing voids in at least one of the streams of liquid energetic material; a mixer for mixing the streams of liquid energetic material to produce the explosive composition; and a blasthole loading hose. The mixer may be provided at the end of the loading hose. A blasting method employs the platform to manufacture and deliver the explosive composition into a blasthole, which composition is subsequently detonated.

    摘要： A method of blasting rock, in mining for recoverable material, comprising drilling blastholes in a blast zone loading the blastholes with explosives and then firing the explosives in the blastholes in a single cycle of drilling, loading and blasting. The blast zone comprises a high energy blast zone in which blastholes are partially loaded with a first explosive to provide a high energy layer of the high energy blast zone having a powder factor of at least 1.75 kg of explosive per cubic meter of unblasted rock in the high energy layer and in which at least some of those blastholes are also loaded with a second explosive to provide a low energy layer of the high energy blast zone between the high energy layer and the adjacent end of those blastholes, said low energy layer having a powder factor that is at least a factor of two lower than the powder factor of said high energy layer. The high energy blasting method provides improved rock fragmentation through increased explosive energy concentration while simultaneously alleviating deleterious environment blast effects.

    摘要： A method of blasting rock, in mining for recoverable material, comprising drilling blastholes in a blast zone (1), loading the blastholes with explosives and then firing the explosives in the blastholes in a single cycle of drilling, loading and blasting. The blast zone comprises a high energy blast zone in which blastholes (2) are partially loaded with a first explosive (5) to provide a high energy layer of the high energy blast zone having a powder factor of at least 1.75 kg of explosive per cubic metre of unblasted rock in the high energy layer and in which at least some of those blastholes are also loaded with a second explosive (6) to provide a low energy layer of the high energy blast zone between the high energy layer and the adjacent end of those blastholes, said low energy layer having a powder factor that is at least a factor of two lower than the powder factor of said high energy layer. The high energy blasting method provides improved rock fragmentation through increased explosive energy concentration while simultaneously alleviating deleterious environment blast effects.
