Abstract: A machine for installing cable bolts, the machine including a drill for drilling a bore into a rock wall, a grout delivery system for delivering grout into the bore, a cable dispensing arrangement for dispensing cable into the bore, an attachment device for attaching a bore anchor to the leading end of the cable prior to the cable being fed into the bore, and a severing device for severing the cable to form a trailing end thereof. A method of installing a cable rock bolt into a bore is also provided.

Abstract: The invention relates to drilling or rockbolting machines, for the execution of underground works, in particular in mining operations. The carrier vehicle comprises a chassis and four wheels, all driving wheels, with two wheels situated on the right-hand side of the chassis of the vehicle and two other wheels situated on the left-hand side of the chassis. The four wheels are of the independent suspension type, having a jack-controlled height, and each comprise rotation-drive means, especially hydraulic motors. The chassis receives, at the front and at the rear, working equipment, such as drilling arms with respective guides, the basic position of which is horizontal and transverse to the direction of displacement of the vehicle. This carrier vehicle is applicable to the realization of a machine, which can be used in mine galleries of low height.

Abstract: The drilling and bolting head (7) of compact structure, is designed for use in mine galleries of small height. It comprises: a transverse table (8) connected to the carrying vehicle, preferably with a device (9 to 12) for lifting this table (8); a slide (13) displaceable along the table (8); an intermediate support (16) displaceable vertically on the slide (13); a vertical beam (21) mounted pivotally on the intermediate support (16); a vertical slideway (23) guided vertically on the beam (21); a drill (26), with a device (33, 34) for the drilling and setting of bolts, which is guided vertically on the slideway (23); motorized device (14, 18, 30) for controlling the various movements. The intermediate support (16) possesses an upper part (20) which can be used as a prop, in combination with a jack (18) arranged along the vertical pivot axis (19) of the beam (21).

Abstract: The invention relates to drilling or rockbolting machines, for the execution of underground works, in particular in mining operations. The carrier vehicle comprises a chassis (2) and four wheels, all driving wheels, with two wheels (4) situated on the right-hand side of the chassis (2) of the vehicle and two other wheels (5, 6) situated on the left-hand side of the chassis. The four wheels are of the independent suspension type, having a jack-controlled height, and each comprise rotation-drive means, especially hydraulic motors. The chassis (2) receives, at the front and at the rear, working equipment, such as drilling arms (25, 26) with respective guides (27, 29), the basic position of which is horizontal and transverse to the direction of displacement (F) of the vehicle. This carrier vehicle is applicable to the realization of a machine which can be used in mine galleries of low height.
