Abstract
951,210. Tunnels. KOPALNIA WEGLA KAMIENNEGO PAWEL. Aug. 2, 1961, No. 28091/61. Heading E1F. A roof support comprises a steel network 2 resting on cross members 1, the major dimension of the meshes of the network extending along the length of the tunnel. The members I are of channel section, and the network is expanded metal sheeting which is fixed to the members at the ends of the support. Joints 3 in the sheeting are formed by overlapping adjacent sheets, inserting projections 6 of a member 5 through overlapping meshes, and moving the sheets so that they tend to separate. In a modification the member 5 may be replaced by a series of waisted pins which may be fixed to a common base.
