Abstract
1522687 Mine and tunnel linings RUHRKOHLE AG 19 Dec 1975 [24 Dec 1974] 52015/75 Heading E1F In a method of supporting a mine or tunnel driven by shotfiring, a crown segment canopy is preassembled from segments 4, 5 of crowns 16-20, distance pieces 13, 14 and at least one lagging mat 21, preferably made from wire mesh. After assemblage e.g. at A 3 and using an erector, the canopy is conveyed into freshly advanced drift A 1 and lifted to the position indicated by chain lines so that distance pieces 25, 26 and lagging mats 22 can be connected between the canopy and the previously set assembly in drift A 2 . The canopy is then further raised into contact with the roof (the position indicated by solid lines), and additional segments 6 and legs 3 are positioned, adjustment being made so that the cross-section of each individual support adapts to the local crosssection of the drift, the periphery of each support contacting the rock at several points, and no backfilling being necessary. As shown, the adjustment for each support is provided by a hydraulic leg 3 acting through a butt cap 2. Alternatively the length of overlap between segments may be varied or the legs and additional segments may be hinged to the canopy and straightened until the supports make tight contact with the rock.
