The 1-2-3-layer support system is often used in deep mines and underground caverns of large span, such as underground machine halls in hydropower plants. This support system is characterised by its flexibility in order to adapt to the prevailing rock condition. In civil tunnels, cable bolting is less used than in mining excavations.
This includes the Proceedings of the international symposium, Abisko, Sweden, 28 August-2 September 1983. Rock bolts today represent the dominant support system in mines and underground structures. Some results and experiences are discussed to give a better understanding of the strength of individual rock bolts and systems of bolts, and the interaction …
Fixed length, dynamic type cables have also been successfully installed using the cable bolting rig. A dynamic cable bolt refers to a cable where a portion of the bolt length is encased in a plastic tube so that it is not in contact with the grout and can stretch along this length in response to ground movement. STEP 1: A hole is
