ABSTRACT:
Broadly, the invention comprises defining a friction rock stabilizer with a configuration which will allow its insertion into an earth structure bore with minimal thrust force, and then deforming the inserted stabilizer, for instance, by forcing an insert thereinto to cause radial expansion of the stabilizer to increase its frictional engagement with the bore surface and produce a high anchorage thereof. The stabilizer set of the invention comprises a stabilizer and at least one oversized expansion insert therefore.
