Longwall Mine Strata Support
Longwall mining integrates hydraulic ceiling supports to prevent caving and control subsidence of the strata above tunnel mines however, smaller rock fragments slip through openings between these supports jeopardizing mine workers lives and disrupting the flow of material extraction. Flexible, fire retardant coated ACEGrid® FR systems create a stable, fire resistant shield along tunnel faces, protecting miners and shearing equipment from imminent rock fragment collapse, and diminish the incidence of underground hazards.
