Abstract (en)
[origin: WO2005113939A1] 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.
