## Abstract

The present invention is a manually bendable rebar bolt for use in ground reinforcement, particularly in mining operations. The rebar bolt is a steel rod having a length and a width. The cross-sectional area of the bolt taken along the width generally perpendicular to said length has a long axis and a short axis. The bendable rebar bolt can be manually bent in a direction generally perpendicular to said long axis.

## Claims

### Claim 1

A manually bendable rebar bolt for use in ground reinforcement, said rebar cable bolt comprising:
a steel rod having a length and a width and a cross-sectional area taken along said width generally perpendicular to said length, said cross-sectional area having an oval or elliptical shape including a long axis and a short axis;
whereby said oval or elliptical shape of said cross-sectional area allows a user to manually bend said steel rod in a direction generally perpendicular to said long axis;
wherein a ratio of said short axis to said long axis is at least about 0.6 and less than 0.8;
wherein a length of said long axis is less than or equal to 0.9 inches and a length of said short axis is greater than or equal to 0.6 inches.

### Claim 2 (depends on 1)

The manually bendable rebar bolt of claim 1, wherein the length of said short axis is about 0.6 inches and the length of said long axis is 0.9 inches.

### Claim 3 (depends on 1)

The manually bendable rebar bolt of claim 1, wherein said rebar is #6 grade 40.

### Claim 4 (depends on 1)

The manually bendable rebar bolt of claim 1, wherein said long axis is less than 0.9 inches and said short axis is greater than 0.6 inches.

### Claim 5

A manually bendable rebar bolt for use in ground reinforcement, said rebar cable bolt comprising:
a rod having a cross-sectional area, said cross-sectional area having an oval or elliptical shape including a long axis and a short axis, said rebar bolt having a width along said long axis and a width along said short axis;
a ratio of said short axis to said long axis is at least about 0.6 and less than 0.8;
wherein a length of said long axis is less than or equal to 0.9 inches and a length of said short axis is greater than or equal to 0.6 inches;
whereby said oval or elliptical shape of said cross-sectional area allows a user to manually bend said rod in a direction generally perpendicular to said long axis.

### Claim 6 (depends on 5)

The manually bendable rebar bolt of claim 5, wherein the length of said short axis is about 0.6 inches and the length of said long axis is 0.9 inches.

### Claim 7 (depends on 5)

The manually bendable rebar bolt of claim 5, wherein said rebar is #6 grade 40.

### Claim 8 (depends on 5)

The manually bendable rebar bolt of claim 5, wherein said long axis is less than 0.9 inches and said short axis is greater than 0.6 inches.

### Claim 9

A manually bendable rebar bolt for use in ground reinforcement, said rebar cable bolt comprising:
a rod having a length a width and a cross-sectional area taken along said width generally perpendicular to said length, said cross-sectional area having an oval or elliptical shape including a long axis and a short axis, a ratio of said short axis to said long axis is at least about 0.6 and less than 0.8, a length of said long axis is less than or equal to 0.9 inches and a length of said short axis is or equal to 0.6 inches;
whereby said oval or elliptical shape of said cross-sectional area allows a user to manually bend said rod in a direction generally perpendicular to said long axis.

### Claim 10 (depends on 9)

The manually bendable rebar bolt of claim 9, wherein said rebar is #6 grade 40.

### Claim 11 (depends on 9)

The manually bendable rebar bolt of claim 9, wherein said long axis is less than 0.9 inches and said short axis is greater than 0.6 inches.
