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.
Claims19
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.
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.
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.
