Abstract

The invention relates to a jointed self-drilling rock bolt (2) comprising at least two sections (4,6,32) joined together, where at least one of the sections (4,6,32) comprises an expandable part (10,26,36), and where the rock bolt (2) is self-drilling, the sections (4,6,32) are threaded together, and expanding fluid (40) for expanding the expandable part (10,26,36) is conveyed through at least one fluid passage (62,63,70,72) within a joint (58,59,60) between two sections (4,6,32) independent of the relative angle of rotation between the respective sections (4,6,32).
