| description | PCT No. PCT/SE79/00223 Sec. 371 Date Jul. 3, 1980 Sec. 102(e) Date Jun. 23, 1980 PCT Filed Nov. 1, 1979 PCT Pub. No. WO80/01003 PCT Pub. Date May 15, 1980.Disclosed is a method for marking out drill holes in accordance with a predetermined drill hole pattern. A direction reference beam (c) is projected in a direction defining the direction of the tunnel and part of a beam (e) is deflected from the reference beam, the part of the beam is passed to a beam derivating means (d2) by means of which the part beam is directed in accordance with a predetermined drill hole pattern onto the rock surface (4) to present thereon images of the part beam at locations of intended drill holes. Correspondingly, a device for executing said method comprises means (d1) for deflecting at least part of a direction reference light beam (c) to form part of a beam (e), and means (d2) to direct the part of the beam onto locations of drilling holes for explosives in accordacne with a predetermined pattern. |
