Abstract

A drilling and bolting tool includes a drill feed for driving a bit to form a hole in a rock surface, a cable feed system, and a resin system. The drill feed includes a frame and a drill head supported on the frame. The cable feed system is coupled to the drill feed, and the cable feed system includes a cable drive for driving a cable into the hole. The resin system includes a hose in fluid communication with a resin supply. The resin system further including a hose drive system for selectively extending the hose into the hole and retracting the hose from the hole.

Claims (38)

1 . A drilling and bolting tool supported by a boom of a mining machine, the drilling and bolting tool comprising:

a drill feed for driving a bit to form a hole in a rock surface, the drill feed including a frame and a drill head supported on the frame;

a cable feed system coupled to the drill feed, the cable feed system including a cable drive for driving a cable into the hole; and

a resin system coupled to the drill feed, the resin system including a hose in fluid communication with a resin supply, the resin system further including a hose drive system for selectively extending the hose into the hole and retracting the hose from the hole,

wherein the cable feed system further includes a tensioning device for applying tension on the cable and a cutter configured to cut the cable while under the tension at a position outside of the hole while leaving a portion of the cable within the hole.

2 . The drilling and bolting tool of claim 1 , wherein the tensioning device includes a hydraulic actuator for applying the tension on the cable.

3 . The drilling and bolting tool of claim 2 , wherein the hydraulic actuator is a hollow hydraulic actuator, wherein the cable extends through the hollow hydraulic actuator, wherein the hydraulic actuator includes a first portion and a second portion extendable relative to the first portion, and wherein the first portion is configured to engage the cable such that extension of the second portion applies the tension on the cable.

4 . The drilling and bolting tool of claim 1 , further comprising a consumables magazine supported on the frame, the consumables magazine configured to store at least one of a drill bit, a bolt, and an adaptor.

5 . The drilling and bolting tool of claim 1 , further comprising a lock plate storage magazine supported on the frame, the lock plate storage magazine storing a plurality of lock plates, each of the lock plates configured to be positioned adjacent the cable.

6 . The drilling and bolting tool of claim 1 , wherein the resin system includes a hose guide for directing the hose into the hole as the hose is extended.

7 . The drilling and bolting tool of claim 1 , wherein the drill head includes a chuck for engaging a drill bit, the drill head being supported for translational movement relative to the frame along an axis.

8 . The drilling and bolting tool of claim 1 , wherein at least a portion of the hose is supported on a reel, wherein the reel is supported on one of a chassis and the boom of the mining machine.

9 . The drilling and bolting tool of claim 1 , further comprising a screen handling device coupled to the frame.

10 . A drilling and bolting tool supported by a boom of a mining machine, the drilling and bolting tool comprising:

a drill feed for driving a bit to form a hole in a rock surface, the drill feed including a frame and a drill head supported on the frame, the drill head including a chuck for engaging a drill bit and a motor for rotating the chuck, the drill head supported for movement relative to the frame along an axis;

a resin system coupled to the drill feed, the resin system including a hose in fluid communication with a resin supply;

a cable feed system coupled to the frame, the cable feed system including a cable drive for driving a cable into the hole, a hydraulic actuator for applying tension on the cable, and a cutter configured to cut the cable at a position outside of the hole while leaving a portion of the cable within the hole; and

a drill tool supporting the drill feed, the resin system, and the cable feed system, wherein the drill tool is movable to selectively align the resin system with the hole in the rock surface without repositioning the boom supporting the drill tool after forming the hole via the drill feed.

11 . The drilling and bolting tool of claim 10 , further comprising a consumables magazine supported on the frame, the consumables magazine configured to store at least one of a drill bit, a bolt, and an adaptor.

12 . The drilling and bolting tool of claim 10 , further comprising a lock plate storage magazine supported on the frame, the lock plate storage magazine storing a plurality of lock plates, each of the lock plates configured to be positioned adjacent the cable.

13 . The drilling and bolting tool of claim 10 , further comprising a hose guide coupled to the drill feed, the hose guide configured to direct the hose into the hole as the hose is extended.

14 . The drilling and bolting tool of claim 10 , further comprising a screen handling device coupled to the frame, the screen handling device including an actuator for engaging a portion of a screen.

15 . A method of operating a drilling and bolting tool, the drilling and bolting tool including a boom supporting a drill tool that includes a drill feed, a cable feed system, and a resin system, the method comprising:

positioning the drill tool adjacent to a work surface such that the drill feed is substantially aligned with a desired location;

operating a drill head of the drill tool to drive a drill bit into the work surface to form a hole at the desired location;

moving the drill tool without repositioning the boom such that the resin system is substantially aligned with the hole;

operating the resin system to inject resin into the hole;

operating the cable feed system to drive a cable into the hole;

engaging a portion of the cable outside of the hole with a tensioning device of the cable feed system to apply tension to the cable; and

actuating a cutter of the cable feed system to cut an exposed end of the cable while under the tension.

16 . The method of claim 15 , wherein moving the drill tool without repositioning the boom comprises rotating the drill tool.

17 . The method of claim 15 , wherein moving the drill tool without repositioning the boom comprises indexing the drill tool.

18 . The method of claim 15 , wherein operating the resin system to inject resin into the hole further comprises:

operating a hose driving device of the resin system to extend a hose having a nozzle into the hole;

injecting resin into the hole via the nozzle; and

retracting the hose from the hole,

wherein the resin mixes with a curing agent either prior to or after being ejected from the nozzle.

19 . The method of claim 15 , wherein the drill tool further comprises a lock plate storage magazine retaining a plurality of lock plates, each lock plate configured to be positioned adjacent the hole.
