Title (EN) METHOD AND APPARATUS IN TUNNELLING
(FR) METHODE ET APPAREIL DE CONSTRUCTION DE GALERIES DE MINE
Abstract: front page image
(EN)Method in tunnelling 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 a part beam (e) is deflected from the reference beam, the part beam then being 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 a part beam (e), and means (d2) to direct the part beam onto locations of holes to be drilled in accordance with a predetermined pattern.
(FR)Methode de construction de galeries de mine pour marquer les trous de mine selon une configuration predeterminee. Un faisceau de reference de direction (c) est projete dans une direction definissant la direction du tunnel et un faisceau partiel (d2) qui dirigent le faisceau partiel selon une configuration de trous de mine predetermines sur la surface de la roche (4) pour y presenter des images du faisceau partiel en des endroits ou l"on projette la construction de trous de mine. Un dispositif de mise en application de cette methode comprend des moyens (d1) pour devier au moins une partie d"un faisceau lumineux de reference directionnel (c) pour former un faisceau partiel (e) et des moyens (d2) pour diriger le faisceau partiel sur des endroits de trous a perforer selon une configuration predeterminee.
