Abstract
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.
Claims14
A polymer mesh for securing to a mine strata for skin control, said polymer mesh comprising:
- a plurality of polymer strands spaced from and substantially parallel with one another extending in a machine direction;
- a plurality of polymer strands spaced from and substantially parallel with one another extending in a cross-machine direction and intersecting the plurality of machine direction polymer strands to create a mesh structure;
- and
- at least one pair of substantially parallel solid bands having a length that extends in both the machine direction and the cross-machine direction, the at least one pair of solid bands being separated by a distance of at least a diameter of an applicable bolt to create an elongated reinforced aperture between the solid bands, said reinforced aperture being traversed by the plurality of polymer strands that run transverse to the direction of the solid bands.
A polymer mesh formed as a roll to be secured to a mine roof or side wall for skin control, said polymer mesh comprising:
- a plurality of polymer strands spaced from and substantially parallel with one another extending in a machine direction;
- a plurality of polymer strands spaced from and substantially parallel with one another extending in a cross-machine direction and intersecting the plurality of machine direction polymer strands to create a mesh structure;
- and
- a plurality of pairs of reinforcing bands in spaced relationship in both the machine direction and the cross-machine direction, a spaced interval between pairs corresponding with a bolt pattern spacing for installing the polymer mesh and securing a roof or side wall in a hard rock mining application.
A polymer mesh for securing in a mine strata for skin control with bolts and associated steel plates, said polymer mesh comprising:
- a plurality of polymer strands spaced from and substantially parallel with one another extending in a machine direction;
- a plurality of polymer strands spaced from and substantially parallel with one another extending in a cross-machine direction and intersecting the plurality of machine direction polymer strands to create a mesh structure;
- and
- at least one pair of substantially parallel solid bands having a length that extends in both the machine direction and the cross-machine direction, the pair of solid bands each having a width and being separated by a distance, both of which are sized to accommodate a size of the associated steel plates such that at least two opposed sides of said plates rest on top of the bands.
