Abstract: A system and method with a self-drilling chemical rock anchor bolt, specifically for use in the mining industry and a device for moving the rock anchor bolt, said rock anchor bolt comprising an anchor tube which encloses an interior, a fixation substance arranged within the interior for bonding the anchor tube on rock, a moveable piston arranged inside the interior for moving the fixation substance outside the anchor tube if the anchor tube is arranged in a borehole inside the rock, a boring head at one back end of the anchor tube, a rinsing channel to supply rinsing fluid, in particular rinsing water to the boring head, an expression channel to supply power fluid, in particular power water to the piston, is to be able to supply both rinsing water as well as power water into an interior of the rock anchor bolt with minor technical expenses.

Abstract: A pot-shaped chuck, which is designed to cooperate with a percussion mechanism (2) of a percussion power tool (3) and an empty space of which is open at a working tool side of the chuck for receiving a working percussion tool (5), includes guide elements (4) coaxial with a percussion axis (A) and in which the working tool (5) is received for joint rotation with the chuck (1) and for a limited axial displacement relative thereto, and a flushing liquid conduit (6) extending along an inner surface (7) forming the pot empty space of the chuck (1).
