Abstract： There is an iron mine goaf below the K7+715-K7+747 section of the Benhuan Expressway. The distribution of thegoaf isdetectedusingthree-dimensional（3D）laserscaning.Thethree-dimensionallaserscanningofthetargetgoafis dividedintotwostages：thefirststageisscanedusingahandheld3Dlaserscanner，andthesecondstageisscanedusinga drilingtype3Dlaserscaner.ThroughtheuseofLASresultsdatanoiseremovalandredundantdataeliminationwerecaried outinthegoafareainthelaterstage.Modelingandencapsulationwerecariedouttogeneratecross-sectionaldiagrams， providingreliableguarantees foron-siteconstructionsafety.Theresearchresultshavecasereferenceandguidancesignificance forsimilar engineering problems.
