Abstract (en)
[origin: WO2015198282A1] 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.
