After initial installation by surveyors, the unique QCD single
rockbolt mount allows the miners to take the unit down and
re-install it in only a few seconds, maintaining a constant line
orientation. Horizontal and vertical tangenting. Very
rugged. Reduced survey time, increased accuracy, smoother
haulageway cross sections, lower tunnel and equipment maintenance
costs, superior miner performance, and decreased ventilation costs
pay for the "mine-laser" many times over each year.
