Abstract: Devices, systems, and methods for securing a wall are disclosed herein. A wall can be secured by attaching a support system to the wall. The support system can include a channel support, an affixation plate, and one or several securement features. The channel support can include a bearing surface that is divided into two portions by a rigidity structure. The rigidity structure can include two rigidity members that together form an M shape. The bearing surface of the channel support can be held against the wall by the affixation plate and the one or several securement features.

Abstract: Devices, systems, and methods for securing portions of a tunnel are disclosed herein. Portions of a tunnel can be secured via attachment of a truss system to the portions of the tunnel. The truss system can include a threadbar, a bearing plate, a tie rod, a first anchor nut, a second anchor nut, and a truss eye. The threadbar can extend through both the truss eye and the bearing plate, and the truss eye and the bearing plate can be separated by the first anchor nut that can be located on the threadbar and between the bearing plate and the truss eye. The first anchor nut can hold the bearing plate against the wall of the tunnel, and the second anchor nut can hold the truss eye against the first anchor nut.

The truss system can include a threadbar, a tie rod, and a truss eye. The truss eye can include a base portion having a base aperture and an eye portion defining an eye. The tie rod can be received and secured in the base aperture of the base portion of the truss eye and the threadbar can be connected to the eye portion of the truss eye.

Abstract: A mine roof and rib support includes a support member comprising a roof support arm and a rib support arm, the roof support arm provided at an angle to the rib support arm, wherein the roof support arm defines an aperture for receiving a mine roof bolt; a bearing plate defining a through-hole, the bearing plate being positioned on the surface of the roof support arm, wherein the bearing plate through-hole is operatively aligned with the roof support arm aperture; and a mine roof bolt extending angularly through the through-hole of the bearing plate and the roof support arm aperture, the mine roof bolt being configured to compress the bearing plate against the support member. The bearing plate is positioned on the surface of the roof support arm away from the angled junction of the roof support arm and the rib support arm.
