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.

礦山資源開采后遺留下采空區(qū)，采空區(qū)的形成容易引發(fā)地表呈現(xiàn)連續(xù)性或非連續(xù)性的沉降變形，存在地表塌陷和頂板冒落的隱患，給采空區(qū)上方的施工人員與設(shè)備帶來極大的安全隱患[1-2]。（剩余3754字）
