Abstract

A method for drilling long holes in rock using a guide arrangement 5 - 8 comprising, on the one hand, an elongate guide element 6 which is intended to be lowered and guide the arrangement in axial displacement in a first previously drilled hole H1 and, on the other hand, a holder element 5 which is connected to the guide element and parallel with it and in which a drilling rod 2 is mounted so as to rotate, which drilling rod is provided with a drill crown 4 intended to drill a second hole H2 next to and parallel with the first hole, which has the same diameter as the second hole. The second hole H2 is drilled at a centre distance from the first hole H1 exceeding the hole diameter, which distance is chosen so that the wall between the holes is razed in conjunction with the drilling. The invention also concerns a guide arrangement for carrying out this method. <IMAGE>
