Abstract
A rock bolt (Fig. 1) is in the form of a pipe (11), which is spaced within a borehole (10) of greater diameter than the outer diameter of the pipe. Chemical anchoring material, for example a two-component adhesive, is pumped into the end of the pipe at the face (10a) of the working so as to pass along the inside of the pipe and at the inner end of the pipe to move outwards (10b) and back along the length of the pipe to fill the space between the pipe and the borehole. The anchoring material may be a two- component adhesive, and the components may be mixed by a pipe- like mixer(13) at the outer end (11a) of the pipe and having fixed guide walls (15) for causing a mixing motion of the components. For keeping the rock bolt pipe equally spaced from the wall of the bore hole before chemical anchoring, the pipe may have coil springs (20, 30) increasing in diameter along the length of the pipe. Fingered gripping means may be mounted within, to only partially obstructed, the inner end 11b of the pipe for gripping the wall of the borehole.
