Abstract: A support bracket for use in supporting overhead cables in mines comprising a post having a first end and a second end with means whereby it can be secured to a support. The second end has limbs extending from either side of the second end which constitute support arms of the bracket to support a cable or hose. The support arms being movable from a cable support position to a cable release position when the cable is subjected to a load in excess of a predetermined level and to return the arms to a cable support position when the excess load has been removed.

Abstract: Integrated drilling and rock bolting member having a threaded end and a distal end with the threaded end connectable to a rotational drive device and the distal end having formed therein a transverse slot which extends longitudinally through the distal end and terminates adjacent the threaded end. The bolt member having opposed inclined wedge faces along a portion of the slot adjacent the distal end. A drilling element having opposed wedge shaped faces which mate with the wedge shaped faces of the bolt member. The drilling element being connected in the slot. In the drilling mode the connection transmits torque and prevents axial displacement between the bolt member and the drill element and in the anchoring mode permits relative axial displacement between the drilling element and the bolt member in response to a predetermined threshold axial force component applied to the bolt member whereby the relative axial displacement secures the bolt member within the hole.
