A mining mesh comprises successive undulated transverse links (1,2,3,4), which are interconnected together at the bent portions of the links, whereby each pair of successive undulated links (1,2), (3,4), . . . forms a row of adjacent rectangular or square meshes (5) having four sides. The mesh is characterised in that at least at one border of the mesh, for each pair of successive links, the last side of the first link (1) is bent upwardly and backwardly over a sharp angle, whereby the end of this last side is hooked around the penultimate (last but one) side of the second link (2) and that the last side of the second link (2) is bent downwardly and backwardly over a sharp angle, whereby the end of this last side is hooked around the penultimate (last but one) side of the first link (1). The advantage is a stronger mining mesh where the overlap between two adjacent rolls can be limited.
