The bolt-setting apparatus for fastening bolts by means of a binding or cementing agent in bore holes which are drilled in the rock contains a drilling device (2) for drilling a hole in the rock, a feed device (3) for pouring a binding or cementing agent into the bore hole, and a displacing device (4) for advancing a bolt into the bore hole. The drilling device (2) is a sectional bar drill for drilling a hole which is longer than the length of the bolt-setting apparatus in the drilling direction. The displacing device comprises a displacing mechanism (20) for advancing a bolt (25) further than the length of the bolt-setting apparatus into the bore hole. The bolt material is preferably a material which is delivered from a strand or roller (34) and is cut to length by means of a cutting device (27) after it has been pushed down to the bottom of the hole. …<IMAGE>… |
