ROCK BOLT

A rock bolt (1), particularly for use in mining, having an axial conduit (3), an anchor nut (14), and an anchor plate (15) supported by the anchor nut (14) for the purpose of placement on the rock (28), should be able to expand sufficiently and possess sufficient tensile strength, and should also be...

Beschreibung
Zusammenfassung:	A rock bolt (1), particularly for use in mining, having an axial conduit (3), an anchor nut (14), and an anchor plate (15) supported by the anchor nut (14) for the purpose of placement on the rock (28), should be able to expand sufficiently and possess sufficient tensile strength, and should also be able to be cut for the purpose of simplified separation of excavated pieces of the rock bolt (1). This problem is addressed in that the axial conduit (3) is at least partially, and particularly entirely, made of metal and plastic, and the at least one component of the axial conduit (3) made of metal and plastic serves to receive tensile forces.
