Abstract

A method for providing a rock bolt ( 2 ) for rock bolting, wherein a rock bolt ( 2 ) having a tubular bolt portion ( 4 ) with a closed cross section is inserted and expanded for bearing contact in a bore hole ( 3 ) in a rock structure ( 1 ). The length of the tubular bolt portion ( 4 ) is determined such that maximum frictional force at pulling inside a bore hole ( 3 ) of a rock bolt with a tubular bolt portion with this length is below a predetermined maximum value. The invention also concerns a rock bolt.
