Abstract
According to an embodiment thereof, the stabilizer set comprises a first, basic, friction rock stabilizer for insertion into a bore formed within an earth structure, and a second, supplementary, friction rock stabilizer, having an annulus for supporting a roof plate, for insertion into the first stabilizer for frictional engagement therewith to provide (a) yieldability of the roof plate and/or (b) reinforcement of the first stabilizer. The methods of the invention, then, comprise inserting a supplementary friction rock stabilizer into a first-inserted friction rock stabilizer in order to reinforce the first, or to provide a necessary yieldability when it is anticipated that the roof plate may become unduly loaded.
