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.

Arrangement (10) for a rock grouting equipment for positioning at least one cartridge (11) is described. The arrangement incorporates at least one magazine (12), arranged around an axis (15). The magazine (12) incorporates at least one space (13), in which space (13) a plurality of said cartridges (11) is stored. The arrangement further incorporates at least one, radially extending, catching device (3, 14), arranged and formed such that it catches at least one cartridge (11) between itself and the inner surface (4) of the magazine body (12), when it performs a rotating movement around the axis (15). The invention also relates to a method.

The invention relates to a method pertaining to a bolting configuration (299) where a drilling unit and a bolting unit are arranged to be supported by a bottom carriage (330) via a respective top carriage (271; 272), wherein said bottom carriage (330) is arranged to be supported by a feed beam (230), relative to which said bottom carriage (330) is displaceable, wherein said top carriages (271; 272) are arranged to alternately be supported by said bottom carriage (330) to alternately be brought into operative engagement and hereby alternately be locked relative to said bottom carriage (330). The method comprises the step of: said locking being performed by a locking configuration (350; 351) comprising at least one hydraulically, pneumatically or electrically displaceably arranged locking pin (350) adapted to be inserted into a locking hole (351) during locking, wherein said locking pin (350) is supported by said one top carriage (271; 272) and said locking hole (351) is arranged in said bottom carriage (330), or vice versa. The invention also relates to a computer program product comprising program code (P) for a computer (200; 210) to implement a method according to the invention. The invention also relates to a bolting configuration and a vehicle equipped with the bolting configuration.

A drilling apparatus including a drill is disclosed for use with a mine roof bolter. The apparatus includes a support adapted to rotate the drill about two different axes. The first axis may be a vertical axis and the second axis may be a horizontal axis. The drilling apparatus includes a mast for supporting the drill and allowing relative movement of the drill with respect to the mast. The drilling apparatus additionally includes an element for longitudinally moving the mast with respect to the support. The drilling apparatus may further include a mesh aligner for aligning the mesh with respect to the drill. A drill guide with a small footprint may also be included which is capable retracting within a housing to avoid interference with a face of the mine when positioning the drilling apparatus.

The present invention relates to a method, and an arrangement for mounting bolts in a material. The method comprises: storing actual data representing the actual positions of bore holes having been bored in the tunnel wall by a drill rig (300), a control unit (800) instructing a bolting device (200) to mount bolts in the bore holes based on the stored actual data.
