AbstractConsidering the hidden danger in the finished stopes in underground metal mines in China, a new cavity data acquisition method based on 3D laser scanning technology is proposed in Dahongshan mine district. This technology uses contactless measurement mode, by which not only the geometric parameter of cavity such as length, area, volume, deformation of roof and wall rock can be gained accurately, but also the security and efficiency of
