1. A panel system to contain landslides due to partial collapse and “rockbursts” for use as reinforcement structures in mine tunnels, slopes and roads together with anchor bolts and plates, the panel system comprising:
a mesh made of metal straps or other tensile or tear resistant material along the length of the strap, wherein each node of the mesh where straps cross is firmly attached with a buckle; and
a frame secured to said mesh, wherein the frame includes flat tension wires near the perimeter of the panel, the wires attached to flat plates with ear flaps or with flat connectors adapted to be placed underneath the plates,
wherein the buckle comprises a plate having two pairs of bendable tabs on each of the opposed sides, wherein the buckle is configured to be placed between the strap surfaces where the two straps meet, one strap perpendicular to the other, a first pair of tabs for wrapping the two edges of one strap in one direction and the second pair of tabs for wrapping the edges of the other strap in the opposite direction, and wherein the four tabs are flattened to trap both perpendicular straps for securing the node, and wherein the node is secured due to friction between the buckle and the node can preserve all the capacity for creep resistance, maximum resistance, and elongation of the straps forming the mesh.
