摘要：A rock-breaking cartridge (10) includes a casing (16) of deformable materialthat forms an internal cavity (22) and a tapered part (82). A seal (90) extends around theoutside of the tapered part (82) and a piston (92) inside the cavity (22) butts against theinside of the tapered part (82) to seal against the inside of the casing (16). A charge (46) isprovided inside the cavity (22) on the side of the piston (92) that is opposite from anarrow end of the tapered part (82) and when the charge (46) is ignited, it causes thepiston (92) to slide towards the narrow end and to force the tapered part (82) and seal(90) to expand. The expansion causes the seal (90) to seal against the inside of a hole inwhich the cartridge (10) has been placed and the seal (90), tapered part (82) and piston(92) form a sturdy plug to contain gasses generated by detonation of the charge (46).
