Mine-roadway or tunnel-roadway lining for the evacuation of, preferably, rock water

摘要

In water-bearing strata in mining and tunnelling, a layer of elastically highly extensible and corrosion-resistant material with rib-shaped reinforcement serves as permanent lining or as part of the permanent lining in order uniformly to evacuate the water in place or pressing forward. In addition to the elastic, highly extensible, corrosion-resistant, rib-reinforced layer, a buffer layer is provided, for example as a flow material, in order to protect the water-evacuating layer from deformations. The layer or layers are connected via bolts or similar devices to the adjoining rock or to the placed concrete layer. <IMAGE>
