A manipulator for providing drilling expendables to a drill head of an underground drill rig includes a gripper that is arranged to selectively grip and release the drilling expendables and to move the gripper between a first position facing a supply magazine and a second position facing the drill head. The manipulator is also arranged to automatically take and return expendables to and from the magazine and drill head. A supply device provides the expendables to a drill head of an underground drill rig having the supply magazine, and to an underground drill rig, as well as an underground mining vehicle.
