Abstract

A frangible cartridge for anchoring a reinforcing element such as a rock-bolt in a borehole in rock strata, for example an underground mine roof, contains as separate components (A) a hydraulic substance mixed with a non-aqueous water-miscible liquid which is inert with respect thereto to form a paste-like mass and (B) an aqueous liquid, preferably water, which is capable of reacting with the hydraulic substance in component A on being brought into contact therewith when in use a reinforcing element is caused to break the cartridge and mix together components A and B within the borehole so as to form a cementitious grout around the reinforcing element, said grout serving when hardened to anchor the reinforcing element in the borehole. This cartridge is safer for use in coal mines and the like than the conventional resinous cartridges and is more reliable than cartridges in which the hydraulic substance is present in a dry form.
