Abstract
A rock drilling and bolting system comprises a drill feed slidable on a drill feed rail for drilling a hole, a bolter feed slidable on a bolter feed rail, the bolter feed having a main bolt driver for driving a rock bolt, a side-mounted bolt driver mounted to the bolter feed rail, the side-mounted bolt driver being disposed rearwardly of the main bolt driver to receive the rock bolt when there is insufficient space to load the rock bolt in the main bolt driver and to drive the rock bolt partially into the hole, and an indexing mechanism for rotating the main bolt driver into alignment with the rock bolt that is partially driven into the hole, wherein the main bolt driver drives the rock bolt fully into the hole.
Claims17
A rock drilling and bolting system comprising:
- a frame supporting a movable drill feed rail and a movable bolter feed rail;
- a drill feed slidable on the drill feed rail for drilling a hole;
- a bolter feed slidable on the bolter feed rail, the bolter feed having a main bolt driver for driving a rock bolt;
- a side-mounted bolt driver mounted to the bolter feed, the side-mounted bolt driver being disposed rearwardly of the main bolt driver to receive the rock bolt when there is insufficient space to load the rock bolt in the main bolt driver and to drive the rock bolt partially into the hole;
- and
- wherein the main bolt driver is rotatable into alignment with the rock bolt that is partially driven into the hole, wherein the main bolt driver drives the rock bolt fully into the hole.
A method of installing ground support using a rock drilling and bolting system having a drill feed rail and a bolter feed rail, the method comprising:
- drilling a hole in a rock;
- retracting the drill feed rail while advancing the bolter feed rail to position the system in a bolt-loading position;
- loading a rock bolt into a side-mounted bolt driver that is spaced further rearward from the rock than a main bolt driver;
- driving the rock bolt partially into the hole using the side-mounted bolt driver;
- indexing the main bolt driver into alignment with the rock bolt;
- and
- driving the rock bolt fully into the hole using the main bolt driver.
A rock drilling and bolting system comprising:
- a frame supporting a movable drill feed rail and a movable bolter feed rail that are connected together via first and second L-shaped pivot arms such that the drill feed rail and bolter feed rail rotate together relative to the frame;
- a drill feed slidable on the drill feed rail for drilling a hole in a rock;
- a bolter feed slidable on the bolter feed rail, the bolter feed having a main bolt driver for driving a rock bolt;
- a side-mounted bolt driver mounted to the bolter feed, the side-mounted bolt driver being disposed rearwardly of the main bolt driver such that the side-mounted bolt driver is further from the rock than the main bolt driver;
- and
- wherein the main bolt driver is rotatable into alignment with the rock bolt after the side-mounted bolt driver has partially driven the rock bolt into the hole, wherein the bolter feed causes the main bolt driver to drive the rock bolt completely into the hole.
