## Abstract

A feed rail for a rock drill is composed of two segments, a first beam defining a first rail segment and a second beam defining a second rail segment. The second beam may be detachably connected to the first beam so that the second beam can be removed altogether from the first beam. This invention enables the feed rail to be shortened, thereby making the feed rail much easier to manoeuvre in mines.

## Claims

### Claim 1

A method of operating a hydraulic feed system for a rock drill, the method comprising:
assembling a feed rail by connecting a first beam defining a first rail segment to a second beam defining a second rail segment;
locking the second beam to the first beam to ensure alignment of the first and second rail segments;
operating the feed system to displace the rock drill along the first and second rail segments of the feed rail; and
drilling rock using the rock drill.

### Claim 2 (depends on 1)

The method as claimed in claim 1 further comprising, when rock drilling is complete:
unlocking the second beam from the first beam;
detaching the second beam from the first beam; and
transporting the hydraulic feed system to a new location.

### Claim 3

A hydraulic feed system for rock drilling, the system comprising:
a first beam defining a first rail segment;
a second beam defining a second rail segment having a channel shape substantially identical to the first rail segment, wherein the second beam is detachably connected to the first beam such that the second beam can be disconnected and removed from the first beam;
a rock drill; and
a hydraulic feed system connected to the rock drill for hydraulically feeding the rock drill along the first and second rail segments.

### Claim 4 (depends on 3)

The system as claimed in claim 3 wherein the second beam is shorter than the first beam.

### Claim 5 (depends on 3)

The system as claimed in claim 3 further comprising a locking mechanism comprising a threaded fastener for locking the first and second beams together.

### Claim 6

A method of installing ground support, the method comprising:
providing a feed rail having a first rail segment and a second rail segment for feeding a rock drill for drilling rock;
disconnecting the second rail segment from the first rail segment to shorten the feed rail; and
installing rock bolts for ground support using only a first rail segment of the feed rail of a hydraulic feed system.

### Claim 7 (depends on 6)

The method as claimed in claim 6 wherein installing rock bolts comprises loading rock bolts from a rock bolt magazine attached to the feed rail.
