Conveyor Tunnel In A Coal Mine

We install concrete floors, spray shotcrete on exposed roof and walls (ribs), place steel sets, and then backfill over the arches for mine conveyor transfer points. This work can be more challenging due to working around moving conveyors and in confined space. The other challenges are regularly presented by the extreme pumping distances for concrete and backfill-often as much as 5,000 LF from the surface.
