    Abstract: An anchoring cartridge for use in anchor bolting in a rock substrate such as an underground mine roof comprises a frangible casing formed from a liquid-impermeable material, the casing containing a particulate liquid-settable solid component, such as a hydraulic cement, which is in contact with a longitudinally extending absorbent material preferably both ends of which communicate with, or are adapted to communicate with, the exterior of the cartridge so that when the cartridge is immersed in an activating liquid for the solid component, such as water, the liquid is drawn into the cartridge by the absorbent material and thereby comes into contact with the solid component over its whole length within the casing. This helps to assist in the formation of a self-setting grouting composition of substantially uniform strength when the cartridge is used in a borehole drilled in the substrate.

    Abstract: Reinforcing or fixing elements such as anchor bolts are anchored in a borehole drilled in a substrate such as an underground mine roof with an anchoring cartridge in which a particulate liquid-settable solid component, for example a hydraulic cement, is contained in a liquid-impermeable casing, the solid occupying a volume which is less than the normal free volume of the casing and the cartridge being at least partially evacuated so as to cause the casing to be in contact with the solid component over substantially its whole length within the casing. This ensures that when the cartridge is immersed in an activating liquid, for example water, and the casing perforated, the activating liquid is drawn rapidly into the evacuated space adjacent the solid component over its whole length thereby helping to ensure the formation of a self-setting grouting composition of uniform strength when the cartridge is used.
