Abstract

A rib support system, a rib support device, a rib support method, a method for manufacturing a rib support device, and a computer readable medium are provided as described herein. The rib support device is configured to support a mine or tunnel rib (or wall) or roof to prevent spalling, and to provide safety and long term protection of tunnel (or open) areas. The rib support device may be made from a high density polyethylene (HDPE) material, or the like, that is resistant to corrosion, has superior overall performance and strength, has few (or no) sharp edges, is light weight, and is easy to handle.

Claims (44)

1. A rib support system for supporting a rib to prevent spalling of the rib and to provide safety and long term protection of a mine, a tunnel or an open area, the system comprising:

a rib support device that is made of a high density polyethylene (HDPE) material, the rib support device being provided in the form of a substantially, longitudinal strap comprising a cross-sectional angle of curvature throughout the length thereof; and

a fastener that is configured to fasten the rib support device to the rib.

2. The rib support system of claim 1 , wherein the longitudinal strap comprises:

the length thereof.

3. The rib support system of claim 1 , wherein the fastener comprises at least one of:

a bolt;

a nut;

a clip;

a clamp;

a pin; and

a rod.

4. The rib support system of claim 1 , wherein the one or more slots comprise at least two slots that are positioned about 48 inches apart.

5. The rib support system of claim 2 , wherein the one or more slots are configured to receive at least one of:

a fastener;

a gas input or output line;

a vacuum line;

an electrical supply line; and

a water line.

6. The rib support system of claim 2 , wherein the one or more slots on the rib support device comprise one or more of:

a circular shape;

a square shape;

a rectangular shape;

an elliptical shape;

an oval shape; or

a triangular shape.

7. The rib support system of claim 2 , wherein the one or more slots comprise a longitudinal length of about 4 inches and a width of about 1.5 inches.

8. The rib support system of claim 1 , wherein the angle of curvature comprises an angle of about 45 degrees.

9. The rib support system of claim 1 , wherein the rib support device is attachable to a tunnel wall or a tunnel roof.

10. The rib support system of claim 1 , wherein of the rib support device comprises:

the substantially longitudinal strap includes two slots positioned along the length thereof,

wherein the longitudinal strap comprises a cross-sectional angle of curvature, and

wherein at least one of the two slots comprises an oval shape.

11. A method for supporting a rib in a mine, a tunnel, or an open area to prevent spalling of the rib and to provide safety and long term protection of the mine, the tunnel or the open area, the method comprising:

providing a high density polyethylene rib support device that includes a predetermined length, a predetermined width, and a predetermined cross-sectional angle of curvature throughout the length thereof;

positioning the rib support device in a location on a rib or a roof;

providing a fastener that is configured to attach the rib support device to the rib or the roof; and

affixing the rib support device to the rib or the roof by means of the fastener.

12. The method of claim 11 , further comprising:

providing another fastener that is configured to further secure the rib support device to the rib or the roof; and

securing the rib support device to the rib or the roof by means of said another fastener.

13. A method of claim 11 , wherein:

the rib support device comprises a substantially longitudinal strap that includes one or more slots positioned along the length thereof; and

the one or more slots are configured to receive a portion of the fastener.
