Abstract
A roadway support (1) is introduced in parallel to the face advancement of a gallery(1) by means of a selective cut heading machine (2) by providing lagging mats (18, 19) in the form of rolled mats (20, 21) downstream of the cutting tool (3) of the selective cut heading machine (2) in two transverse planes (14, 15) that are arranged behind one another in the longitudinal heading direction in circumferential offset relationship. The lagging mats (18, 19) are then unrolled simultaneously to the face advancement in the longitudinal heading direction so as to overlap laterally and are instantly aligned upon the rock. Once the lagging mats (18, 19) have been entirely unrolled, the working steps are successively repeated in accordance with the length of the face advancement with new lagging mats (18, 19) that adjoin the lagging mats (18, 19) previously laid. The roadway support (7) is introduced at a distance to the cutting tool (3) while fixing the lagging mats (18, 19).
