Mining Systems

75% Max. Reduction in Installation Time
MSHA Compliant
  • Ideal for underground mining applications like roof and rib control as well as long-wall shield recovery screens
  • Inby-outby stiffness for production installation from miner/bolters
  • Rib-rib flexibility allowing continous roof-to-rib reinforcement for securing entry corners
  • Strength equivalent to 8 gauge, welded wire modules, but 1/7 the weight
  • White, reflective color for increased entry brightness
Solution Overview

Primary roof and rib control of underground openings is traditionally accomplished by metallic supports that may have a variety of configurations. Perhaps the most common are steel roof and rib bolts, which are generally spaced on a regular pattern within the roof, and sometimes ribs of the entry. These primary support devices are intended to prevent catastrophic failure of the openings. They are generally not suited to prevent spalling between their isolated locations.

Tensar's heavy-duty polymer geogrid can provide supplemental roof and rib skin control for the most demanding conditions. Tensar's Mining Systems are a family of polymeric grid products that are lightweight and easy to handle. They are impervious to acidic environments and have very similar strength characteristics to steel, but at a fraction of steel's weight. These properties add up to a drastic reduction in back, hand, and facial installation injuries, due to product weight and flexibility. Compared with metal reinforcement, Tensar Mining Systems can reduce installation and material handling time up to 75%.

SKUs

Tensar's Mining Systems include BX3326, TX196FR, Minex Rock Mesh, and UX3340 roof mats.

Flame Retardant

The flame-retardant additive is injected during the batching stage of production and complies with Mine Safety and Health Administration (MSHA) CFR30, Part 7, for permanent installations. Further, the polymer grid structure will not corrode in a damp environment and is totally impervious to acidic conditions.

Roof and Rib Control

Tensar geogrid, teamed with Minex Rock Mesh, provides effective roof and rib control for soft minerals as well as the most demanding hard rock and tunneling applications. Tensar mining grid meshes are impervious to acidic environments and have very similar characteristics to steel, but at a fraction of steel's weight. These properties add up to a drastic reduction in back, hand, and facial installation injuries, due to product weight and flexibility. Lightweight, easy-to-handle Tensar Mining Systems easily reduce installation and material handling time by up to 75%.

Longwall Screening

Moves that traditionally took weeks several years ago have been reduced to days, enabling customers to save thousands of dollars working in the most brutal of conditions. Flame-retardant Minex Rock Mesh maintains similar weight characteristics to Tensar mining grid, yet is over eight times stronger with increased flexibility.

Resistive Unrolling Tensar TriAx®  Geogrid

Resistive unrolling allows TriAx mining grid to be installed from miner/bolters and bolting machines without the need for brackets that cause downtime and needless maintenance. TriAx mining grid rolls are injected with expandable foam or secured with cable ties that allow the roll to be suspended from a bolter or miner/bolter and installed with a predetermined amount of resistance, which prevents the roll from undoing itself during installation and keeps TriAx mining grid tight against the roof. The benefits include reduced entry development time, increased driveage, reduced worker injuries, and eliminating the need for screen rehabilitation.
