Abstract
Boring guide for drilling a slot in a rock, the drilling arrangement being used to drill a row of pilot holes in the rock at a distance from one another, and the neck between the holes being drilled by means of the boring guide 6 to form a slot, which boring guide comprises a drill-rod support sleeve 7 and, fastened thereto, a drilling support 8 supported on the pilot hole next to the neck, which support consists of a tubular wall support 9. Fastened on the outer surface of the wall support, on the opposite side to the support sleeve are holding or guiding plates or ribs 16 which are parallel both to one another and to the support sleeve and the wall support. The lower edge of the wall support also comprises an indentation 18, via which drilling sludge can drain into and out through the wall support. <IMAGE>
