Abstract
865,761. Fluid-pressure blasting cartridges. AUSTLAND Ltd. Jan. 8, 1958 [Jan. 21, 1957], No. 2134/57. Class 9(1). A fluid-pressure blasting device as described in Specification 865,760 contains a column of liquid such as water between the reservoir 5 and the outlet ports 8. The liquid may be confined between rupturable partitions 6, 9 or may be pumped into the tube 1 after the device has been sealed in a borehole through a connection 10. The membrane 9 may be replaced by a rubber membrane placed over the parts 8, which are inclined rearwardly so that the fluid discharge tends to retain the device in the borehole. Some of the ports may be radial and may be spaced along a substantial length of the tube 1, the ports then being arranged along a line parallel to the axis, so that the discharge may be applied in a given angular direction. Pivoted claws, not shown, may be used to secure the device in the borehole.
