摘要： A polymer mesh for skin control in hard rock mining conditions is provided. The polymer mesh is manufactured using a knitted or woven design that further includes one or more pairs of solid cut-resistant bands. The bands are positioned in pairs, each band in a pair having a width of at least about 2.5″ and being generally parallel with the other band. The bands are spaced from one another at a distance of between about 1.5″ and about 4″ to create a reinforced aperture between the bands. One or more reinforcement bolts are installed within the aperture with the bands on opposing sides of each bolt buffering the edges of the steel plates associated with the bolts to prevent the plates from tearing the polymer mesh.

摘要： An integral polymer grid with a plurality of interconnected, oriented polyethylene terephthalate strands and an array of openings therein is made from a polyethylene terephthalate sheet-like starting material having holes or depressions therein that form the openings when the sheet-like material is uniaxially or biaxially stretched. The grid has a higher tensile strength to weight ratio and a higher creep reduced strength to weight ratio than corresponding ratios associated with a grid made from a non-polyethylene terephthalate starting material.

摘要： An integral geogrid includes a plurality of interconnected, oriented strands having an array of openings therein that is produced from a coextruded multilayer polymer sheet starting material. By virtue of the construction, the coextruded multilayer sheet components provide a crystalline synergistic effect during extrusion and orientation of the integral geogrid, resulting in enhanced material properties that provide performance benefits to use of the integral geogrid in soil geosynthetic reinforcement.

摘要： An integral polymer grid with a plurality of interconnected, oriented polyethylene terephthalate strands and an array of openings therein is made from a polyethylene terephthalate sheet-like starting material having perforations or indentations therein that form the openings when the sheet-like material is uniaxially or biaxially stretched. The grid has a higher tensile strength to weight ratio and a higher creep reduced strength to weight ratio than corresponding ratios associated with a grid made from a non-polyethylene terephthalate starting material.
